Given the following information:Mass of the system, m = 20 kg.Damping coefficient, b = 6 Ns/m.Force, F = 90 N.Frequency of applied force, f = ?Applied force angular frequency, w = 6 rad/s.Forced vibration equation:F(t) = F0 sin(wt)where F0 = 90 N and w = 6 rad/s.Under the action of the force F, the mass m will oscillate.The equation of motion for the mass-spring-damper system is given by:$$\mathrm{m\frac{d^{2}x}{dt^{2}}} + \mathrm{b\frac{dx}{dt}} + \mathrm{kx = F_{0}sin(\omega t)}$$where k is the spring constant.x(0) = 0 and x'(0) = 0.As we have the damping coefficient (b), we can calculate the damping ratio (ζ) and natural frequency (ωn) of the system.Damping ratio:$$\mathrm{\zeta = \frac{b}{2\sqrt{km}}}$$where k is the spring constant and m is the mass of the system.Natural frequency:$$\mathrm{\omega_{n} = \sqrt{\frac{k}{m}}}$$where k is the spring constant and m is the mass of the system.Resonant frequency:$$\mathrm{\omega_{d} = \sqrt{\omega_{n}^{2}-\zeta^{2}\omega_{n}^{2}}}$$At resonance, the amplitude of the system will be maximum when forced by a sinusoidal force of frequency equal to the resonant frequency.Resonant frequency:$$\mathrm{\omega_{d} = \sqrt{\omega_{n}^{2}-\zeta^{2}\omega_{n}^{2}}}$$$$\mathrm{\omega_{d} = \sqrt{(6.57)^{2}-(-2.88)^{2}} = 6.98 rad/s}$$Hence, the frequency of applied force at which resonance will occur is 6.98 rad/s.

The frequency of the applied force at which resonance will occur is ω = 2√5 rad/s.

To determine the frequency of the applied force at which resonance will occur, resonance happens when the frequency of the applied force matches the natural frequency of the system. The natural frequency can be determined using the formula:

ωn = √(K / M),

where ωn is the natural frequency, K is the spring constant, and M is the mass of the system.

Substituting the given values of K = 400 N/m and M = 20 kg into the equation, we can calculate the natural frequency ωn.

ωn = √(400 N/m / 20 kg) = √(20 rad/s²) = 2√5 rad/s.

Therefore, the frequency of the applied force at which resonance will occur is ω = 2√5 rad/s.

The correct question is given as,

M= 20kg

Fo = 90 N

ω = 6 rad/s

K = 400 N/m

C = 125 Ns/m

Explanation:

The main answer for amplitude is as follows:

(a) The spring constant of the given system can be found using the following formula: k= 4π²m/T²Where k is the spring constant, m is the mass of the block, and T is the period. Substituting the given values: k= 4π²(20.0 g)/(1.50 s)²k = 8.38 N/m

(b) The speed of the block can be found using the conservation of energy, which states that the initial potential energy of the spring must be equal to the kinetic energy of the block when it is compressed by 0.180 m. mgh = (1/2)mv²The mass cancels out, so we can solve for v:v = √(2gh)Where h is the compression of the spring. Substituting the given values: v = √(2(9.81 m/s²)(0.180 m))v = 1.66 m/s

(c) The magnitude of the force can be found using Hooke's law, which states that the force exerted by the spring is proportional to the amount it is compressed or stretched. F = -k x Where x is the displacement from the equilibrium position. Substituting the given values: F = -(8.38 N/m)(0.180 m)F = -1.51 N The negative sign indicates that the force is in the opposite direction of the displacement, so it is to the left.

(d) The frequency of oscillation can be found using the following formula: f = 1/T Substituting the given values: f = 1/1.50 sf = 0.667 Hz Therefore, the frequency of oscillation of the block is 0.667 Hz.

Answer:

All living organisms store genetic information using the same molecules DNA and RNA. Genes are maintained over an organism's evolution, however, genes can also be exchanged or "stolen" from other organisms.

Yes, we have paired data because each specimen was tested using both procedures (Test 1 and Test 2).

(i) Null hypothesis (H0): The mean difference between Test 1 and Test 2 is not 0.1 units less.

(ii) Alternative hypothesis (Ha): The mean difference between Test 1 and Test 2 is 0.1 units less.

To test this claim, we will use a one-sided 95% confidence interval.

Mean difference = 0.1 units

Standard deviation of the difference = Standard deviation of Test 1 - Standard deviation of Test 2

Mean of Test 1 (M1) = 1.3

Mean of Test 2 (M2) = 1.6625

Standard deviation of Test 1 (S1) = 0.207

Standard deviation of Test 2 (S2) = 0.2774

Sample size (n) = 8

Standard deviation of the difference:

SD_diff = \(\sqrt{(S1)^{2} /n+ (S2)^{2}/} n\\\\)

SD_diff =\(\sqrt{(0.207)^{2}/8 +(0.2774)^{2}/8 }\)

SD_diff = 0.1727

Standard error (SE) of the difference:

SE_diff = SD_diff / sqrt(n)

            = 0.1727 / sqrt(8)

SE_diff = 0.0611

The one-sided 95% confidence interval for the mean difference is calculated as follows:

Lower limit = Mean difference - (1.645 * SE_diff)

Upper limit = Mean difference

Lower limit = 0.1 - (1.645 * 0.0611)

Lower limit = 0.1 - 0.1004

Lower limit = -0.0004

Since the lower limit of the one-sided 95% confidence interval (-0.0004) is greater than 0, we fail to reject the null hypothesis at a 0.05 level of significance. There is insufficient evidence to support the claim that Test 1 generates a mean difference 0.1 units less than Test 2.

(v) Assumptions required to develop the confidence interval:

1. The data follows a normal distribution.

2. The paired observations are independent of each other.

3. The standard deviations of Test 1 and Test 2 are representative of the population standard deviations.

Answer:

The first historical account of muscular dystrophy appeared in 1830, when Sir Charles Bell wrote an essay about an illness that caused progressive weakness in boys. Six years later, another scientist reported on two brothers who developed generalized weakness, muscle damage, and replacement of damaged muscle tissue with fat and connective tissue. At that time the symptoms were thought to be signs of tuberculosis. In the 1850s, descriptions of boys who grew progressively weaker, lost the ability to walk, and died at an early age became more prominent in medical journals. In the following decade, French neurologist Guillaume Duchenne gave a comprehensive account of 13 boys with the most common and severe form of the disease (which now carries his name—Duchenne muscular dystrophy). It soon became evident that the disease had more than one form, and that these diseases affected people of either  and of all ages. Muscular dystrophy (MD) refers to a group of more than 30 genetic diseases that cause progressive weakness and degeneration of skeletal muscles used during voluntary movement. The word dystrophy is derived from the Greek dys, which means "difficult" or "faulty," and troph, or "nourish.

The first person who regularly turned a telescope to astronomical observations and published his findings was Galileo Galilei, an Italian astronomer, physicist, and mathematician. Born in 1564, Galileo played a significant role in the scientific revolution during the 17th century.

His use of the telescope revolutionized the field of astronomy by enabling him to observe celestial bodies with unprecedented detail and accuracy.

Galileo began his astronomical work in 1609, inspired by the invention of the telescope in the Netherlands. He quickly improved the design, increasing its magnification capabilities. This allowed him to make several groundbreaking discoveries, such as the craters and mountains on the moon, the phases of Venus, and the four largest moons of Jupiter (later named the Galilean moons).

Galileo's observations contradicted the prevailing geocentric model of the universe, which placed Earth at the center. His discoveries supported the heliocentric model proposed by Nicolaus Copernicus, where the planets revolve around the sun. This sparked significant controversy, as it challenged the established teachings of the Catholic Church.

Galileo published his findings in several works, including "The Starry Messenger" in 1610 and "Dialogue Concerning the Two Chief World Systems" in 1632. His commitment to sharing his observations and promoting scientific inquiry laid the foundation for modern astronomy and contributed to a more accurate understanding of our place in the universe.

The pressure transmitted in the hydraulic fluid is 4000 Pa and the mass of the load is 40.82 kg.

To determine the pressure transmitted in the hydraulic fluid, we can use the formula:

Pressure = Force / Area

Given that a force of 20 N is applied to the small piston and the cross-sectional area of the small piston is 0.005 m², we can calculate the pressure as follows:

Pressure = 20 N / 0.005 m²

Pressure = 4000 Pa

Therefore, the pressure transmitted in the hydraulic fluid is 4000 Pa.

To determine the mass of the load, we need to consider the equilibrium of forces in the hydraulic system. The force applied to the small piston is transmitted to the larger piston. Since the system is in equilibrium, the force exerted by the larger piston must balance the force applied to the small piston.

Using the formula:

Force = Pressure × Area

The force exerted by the larger piston can be calculated as follows:

Force = Pressure × Area (large piston)

Force = 4000 Pa × 0.1 m²

Force = 400 N

Therefore, the force exerted by the larger piston is 400 N.

Since force is equal to mass multiplied by acceleration (F = m × a), and the acceleration due to gravity is approximately 9.8 m/s², we can calculate the mass of the load:

400 N = mass × 9.8 m/s²

Solving for the mass:

mass = 400 N / 9.8 m/s²

mass ≈ 40.82 kg

Fcd = 23.09 ft (tension)

Fcj = 11.54 ft (compression)

Fdj = -10 ft (compression)

To determine the forces in members cd, cj, and dj, we need to analyze the truss and solve for the reactions at the supports.

First, we can find the reaction at support A by taking the sum of the vertical forces to be zero

RA + RB - 20 = 0

RA + RB = 20

Next, we can take moments about point B to find the reaction at support A

RA * 5 + 10 * 7 - 15 * 3 = 0

RA = 3

RB = 17

Now that we have found the reactions at the supports, we can use the method of joints to solve for the forces in the members. Starting at joint C, we can write the equations of equilibrium for the horizontal and vertical forces

Horizontal Fcd * cos(60) - Fcj = 0

Vertical  Fcd * sin(60) + Fdj = 3

Solving for Fcj and Fdj in terms of Fcd, we get

Fcj = Fcd * cos(60)

Fdj = 3 - Fcd * sin(60)

Next, we can move to joint D and write the equations of equilibrium for the horizontal and vertical forces

Horizontal Fdj = 0

Vertical Fcd * sin(60) - Fdj - 20 = 0

Solving for Fcd and plugging in the values for Fdj, we get

Fcd = 20 / sin(60) = 23.09 ft

Finally, we can use the equations we found earlier to solve for Fcj and Fdj

Fcj = Fcd * cos(60) = 11.54 ft

Fdj = 3 - Fcd * sin(60) = -10 ft

Therefore, the forces in members cd, cj, and dj are

Fcd = 23.09 ft (tension)

Fcj = 11.54 ft (compression)

The frequency at which the current in the circuit will be greatest is approximately 2239.44 Hz. The current amplitude at the resonant frequency will be approximately 0.0149 A. The current amplitude at an angular frequency of 399 rad/s will be approximately 0.0152 A. The source voltage will lag the current.

To determine the frequency at which the current in the circuit will be greatest, we can calculate the resonant frequency of the series circuit. The resonant frequency is the frequency at which the impedance is minimum, resulting in maximum current.

The resonant frequency (fr) can be found using the formula:

fr = 1 / (2π√(LC))

Where L is the inductance and C is the capacitance of the circuit.

Given:

Resistance (R) = 205 Ω

Inductance (L) = 0.397 H

Capacitance (C) = 5.08 μF = 5.08 x \(10^{-6}\) F

Converting the capacitance to Farads:

C = 5.08 x \(10^{-6}\)  F

Now we can calculate the resonant frequency:

fr = 1 / (2π√(LC))

= 1 / (2π√((0.397 H) * (5.08 x \(10^{-6}\)  F)))

≈ 2239.44 Hz

Therefore, the frequency at which the current in the circuit will be greatest is approximately 2239.44 Hz.

To find the current amplitude at this frequency, we can use the formula for the current amplitude in a series RLC circuit at resonance:

I = V / R

Where V is the amplitude of the source voltage and R is the resistance.

Given:

Amplitude of the source voltage (V) = 3.06 V

Resistance (R) = 205 Ω

Substituting the values:

I = (3.06 V) / (205 Ω)

≈ 0.0149 A

Therefore, the current amplitude at the resonant frequency will be approximately 0.0149 A.

To find the current amplitude at an angular frequency of 399 rad/s, we can use the formula for the current amplitude in a series RLC circuit:

I = V / √(\(R^{2}\) + \((wL - 1 / wC)^{2}\))

Given:

Angular frequency (ω) = 399 rad/s

Resistance (R) = 205 Ω

Inductance (L) = 0.397 H

Capacitance (C) = 5.08 μF = 5.08 x \(10^{-6}\)  F

Substituting the values:

I = (3.06 V) / √(\((205 ohm)^{2}\) + ((399 rad/s) * (0.397 H) - 1 / \((399 rad/s * (5.08* 10^{-6} F))^{2}\)

Calculating the expression:

I ≈ 0.0152 A

Therefore, the current amplitude at an angular frequency of 399 rad/s will be approximately 0.0152 A.

Facilitated diffusion differs from ordinary diffusion in that (E) the rate of molecular movement is limited by the number of available carrier molecules. In contrast, ordinary diffusion does not rely on carrier molecules, so the rate of diffusion is not limited by their number.

Facilitated diffusion is a process in which a substance moves through a cell membrane without the requirement for energy. Facilitated diffusion requires membrane transport proteins to assist in the diffusion of certain molecules and ions throughout the cell membrane. The cell membrane proteins are known as transporters or carriers.

Molecules such as glucose, amino acids, and nucleotides can be transported using facilitated diffusion, which is the movement of molecules across the cell membrane down their concentration gradient. How does facilitated diffusion differ from ordinary diffusion? Facilitated diffusion differs from ordinary diffusion in the sense that the rate of molecular movement is limited by the number of available carrier molecules.

While ordinary diffusion occurs spontaneously, facilitated diffusion does not occur spontaneously but rather needs carrier proteins to help in the transport of molecules. In the case of facilitated diffusion, the carrier molecules aid in the movement of molecules from an area of high concentration to an area of lower concentration. Facilitated diffusion is a process that takes place across a semi-permeable membrane, where larger and more charged molecules must pass through protein channels to reach their final destination.
