A two-slit pattern is viewed on a screen 1.50m from the slits.If the two third-order minima are 23.5cm apart, what is the width of the central bright fringe?
Answers
The width of the central bright fringe is 0.50 m.
In a double-slit experiment, the distance between adjacent bright or dark fringes is given by:
dsinθ = mλ
where d is distance between the slits, θ is the angle, m is the order of the fringe (m = 0 for the central bright fringe), and λ is the wavelength of light.
Since screen is 1.50 m from the slits. If two third-order minima are 23.5 cm apart, then the distance between third-order minima and the central bright fringe is:
y = mλL/d
where L is the distance between the slits and the screen. For m = 3, λ = (2/3)*d = 2d/3, L = 1.50 m, and d is unknown.
Substituting these values and solving for d, we get:
23.5 cm = 3*(2d/3)*(1.50 m)/d
23.5 cm = 3*(1.50 m)*2/3
23.5 cm = 3*1.00 m
Therefore, the distance between adjacent bright fringes is 1.00 m.
The width of the central bright fringe is determined by the distance between the two adjacent dark fringes, which is half the distance between adjacent bright fringes.
Therefore, the width of the central bright fringe is:
w = (1/2)*(1.00 m) = 0.50 m
So the width of the central bright fringe is 0.50 m.

A race car is moving with a speed of 280 Km/hr around a circular track with a radius of 320 m. The car and driver have a combined mass of 820 kg. What is the magnitude of the centripetal force that is acting on the car and driver?
Answers
The determine the magnitude of the centripetal force acting on the car and driver, we can use the formula Fc = mv^2/r, where Fc is the centripetal force, m is the combined mass of the car and driver, v is the speed of the car, and r is the radius of the circular track.
The First, we need to convert the speed from Km/hr. to m/s by dividing 280 by 3.6, which gives us 77.78 m/s. Then, we can plug in the values into the formula: Fc = (820 kg) x (77.78 m/s) ^2 / (320 m). Simplifying this equation gives us a centripetal force of approximately 15,066 N. This means that the track is exerting a force of 15,066 N towards the center of the circular path, keeping the car and driver moving in a circular motion. It is important to note that the determine the magnitude of the centripetal force increases as the speed or radius of the circular path increases. This force is also necessary for any object moving in a circular path, and without it, the object would move in a straight line instead.

compared to when the cosmic microwave background was first released, the radiation of the cosmic microwave background today is _____ and has most of its photons at _____ wavelengths.
Answers
Compared to when the cosmic microwave background (CMB) was first released, the radiation of the CMB today is more redshifted and has most of its photons at longer wavelengths.
The cosmic microwave background radiation is residual radiation from the early universe, specifically from the time when the universe became transparent to light. At that time, known as recombination, photons were able to travel freely through space, and the CMB was released.
Since the time of recombination, the universe has been expanding, causing the wavelengths of the CMB photons to stretch or redshift. This redshift has shifted the radiation from its initial high-energy, short-wavelength state to a lower-energy, longer-wavelength state.
Today, the CMB is observed as microwave radiation, which has longer wavelengths compared to the original release. The majority of the photons in the CMB are now found in the microwave part of the electromagnetic spectrum, with peak wavelengths around 1 mm.
In summary, the radiation of the cosmic microwave background today is more redshifted, with most of its photons at longer wavelengths, specifically in the microwave region of the electromagnetic spectrum.

When any object is launched in the air, it moves up to the maximum height where the velocity of the object becomes zero, or we can say the total energy becomes potential. if air friction is neglected, what are the forces acting on the object after it is released
Answers
After an object is launched in the air and it reaches its maximum height, the forces acting on the object are the force of gravity and the normal force.
The force of gravity is pulling the object downward towards the Earth, while the normal force is pushing the object upward to counteract the force of gravity.
These forces are equal and opposite, so they cancel each other out, causing the object to remain at a constant height until another force acts on it. This is known as the principle of equilibrium.
If air friction is neglected, there are no other forces acting on the object. It will continue to move at a constant velocity until another force, such as air resistance or a collision with another object, changes its motion.
In summary, the forces acting on the object after it is released are the force of gravity and the normal force, which are equal and opposite, causing the object to remain at a constant height until another force acts on it.

What is the ratio of the orbital velocity of a terrestrial planet orbiting at 5.00 AU from its star to that of a giant planet orbiting at 19.00 AU? NOTE: You may assume circular orbits.
Answers
The ratio of the velocities of the two planets is 0.482
The velocity v of the planet in its circular orbit can be calculated using the following formula: v = 2πr/T
So, v = 2πr/ T
Where T is the time period of revolution of the planet around the star, r is the radius of the circular orbit, and v is the velocity of the planet in its orbit.
Since we can assume circular orbits, we have v ∝ r^-1/2.
Therefore, the ratio of velocities of the two planets is given as follows:
V1 / V2 = (r1 / r2)^(1/2)
Where, V1 is the velocity of the terrestrial planet orbiting at 5.00 AU, r1 is the radius of the orbit of the terrestrial planet around the star, V2 is the velocity of the giant planet orbiting at 19.00 AU, and r2 is the radius of the orbit of the giant planet around the star.
Therefore, substituting r1 = 5.00 AU, r2 = 19.00 AU, we get the ratio of the velocities of the two planets as:
V1 / V2 = (5/19)^(1/2)
V1 / V2 = 0.482

a 72.9-kg base runner begins his slide into second base when moving at a speed of 3.93 m/s. the coefficient of friction between his clothes and earth is 0.693. he slides so that his speed is zero just as he reaches the base.(a)how much mechanical energy is lost due to friction acting on the runner?
Answers
The mechanical energy lost due to friction acting on the runner is 1095.7 J.
What is Energy?
Energy is a fundamental concept in physics that refers to the ability of a system to do work. In simpler terms, energy is the capacity of an object or system to perform work, move, or cause changes in matter.
To account for this, we can use the work-energy principle, which states that the work done on an object is equal to the change in its kinetic energy:
W = ΔK
where W is the work done on the runner by friction and ΔK is the change in the runner's kinetic energy.
The work done on the runner by friction is given by:
W = μkmgd
where μk is the coefficient of kinetic friction (0.693), d is the distance over which the runner slides (assumed to be the same as the distance between the bases, 15.24 m), and the other variables are as defined above.
W = (0.693)(72.9 kg)(9.81 m/\(s^{2}\))(15.24 m)
W = 1095.7 J
The change in the runner's kinetic energy is given by:
ΔK = \((1/2)mvf^{2}\) - \((1/2)mvi^{2}\)
where vf is the final speed of the runner (zero) and vi is the initial speed of the runner (3.93 m/s).
ΔK = (1/2)(72.9 kg)\((0 m/s)^{2}\) - \((1/2)(72.9 kg)(3.93 m/s)^{2}\)
ΔK = -1041.9 J
The negative sign indicates that the runner's kinetic energy has decreased, as expected.
Therefore, the actual mechanical energy lost due to friction is:
ΔE = W = 1095.7 J

Answer:
Explanation:
a) From the diagram, the load will be expressed in newton. The load will be the weight of the box on the inclined plane.
Load = mass * acceleration due to gravity.
Given the mass of the object = 100kg
acceleration due to gravity = 9.8m/s²
Load (in Newton) = 100*9.8
Load (in Newton) = 980N
b) The formula for calculating the velocity ratio of an inclined plane is expressed as VR = 1/sinθ where θ is the angle of inclination.
Given θ = 30°,
VR = 1/sin30°
VR = 1/0.5
VR = 1/(1/2)
VR = 1* 2/1
VR = 2
The velocity ratio is 2.
c) Length of the inclined plane can be calculated using the SOH, CAH, TOA trigonometry identity.
According to SOH, sinθ = opposite/hypotenuse
sin30° = 1/2 = opp/hyp
This shows that the opposite side of the triangle is 1 and the hypotenuse is 2. The length if the inclined is the length of the longest side i.e the hypotenuse. Hence the length of the inclined plane is 2m
d) Mechanical Advantage is the ratio of the load to the effort applied on an object.
Given the Load = 980N and the effort applied to the load on the incline plane = 400N
MA = Load/Effort
MA = 980/400
MA = 2.45
e) Efficiency = MA/VR * 100
Efficiency = 2.45/2 * 100
Efficiency = 122.5%
