which famous scientist is associated with the force of gravity?

The potential drop across \(R_2\) is 7.455 V.  

The potential drop across  \(R_2\), we need to know the voltage drop across \(V_2\)  and the current flowing through  \(R_2\).

The voltage drop across \(R_1\) can be calculated using Ohm's law:

\(V_1\)  = I *  \(R_1\)

here \(V_1\) is the voltage drop across  \(R_1\), I is the current flowing through  \(R_1\), and \(V_2\) is voltage and the resistance of  \(R_1\).

The current flowing through  \(R_1\) is given, so we can calculate the voltage drop as follows:

\(V_1\) = (11.38 A) * (0.02899 m)

= 3.125 V

The current flowing through  \(R_2\) can be calculated using Ohm's law:

I * \(R_2\) = \(V_2\)  /  \(R_2\)

here \(V_2\)  is the voltage across  \(R_2\),  \(R_2\) is the resistance of  \(R_2\), and I is the current flowing through  \(R_2\).

We know that the potential difference between the ends of  \(R_2\) is 2.70 V, so we can calculate the current flowing through  \(R_2\) using the equation:

I = \(V_2\)  /  \(R_2\)

I = 2.70 V / 0.02899 m

= 92.28 A

Therefore, the potential drop across \(R_2\) is:

\(V_2\) = I *\(R_2\) *  \(R_2\)

= (2.70 V) * (0.02899 m)

= 7.455 V

Therefore, the potential drop across  \(R_2\) is 7.455 V.

In Conclusion, By evaluating the electric field and magnetic field at the surface of the long transmission cable, we can use the expression s~ = (1/μ₀) * (E × B) to find the electromagnetic energy flux. This flux represents the rate at which energy is flowing through the cable's surface due to the current.

To evaluate the electromagnetic energy flux, denoted by s, at the surface of a long transmission cable carrying the current i(t), we can use the expression s~.
The expression for s~ is given by

s~ = (1/μ₀) * (E × B),

where E represents the electric field and B represents the magnetic field.
To evaluate s~, we need to find the electric and magnetic fields at the surface of the cable.
1. Find the electric field (E) at the surface of the cable:
  - Apply Gauss's law to a cylindrical surface around the cable.
  - Since the cable is long, the electric field is radial and has the same magnitude at any point on the surface.
  - Use the formula

E = V/ℓ,

where V is the voltage across the cable and ℓ is the length of the cable segment.
  - In this case, the voltage V can be obtained using Ohm's law:

V = i(t) * R,

where R is the resistance of the cable segment.
2. Find the magnetic field (B) at the surface of the cable:
  - Apply Ampere's law to a circular loop surrounding the cable.
  - Due to the symmetry of the cable, the magnetic field will form concentric circles around it.
  - Use the formula

B = (μ₀ * i(t))/(2π * r),

where μ₀ is the permeability of free space and r is the distance from the center of the cable.
3. Substitute the values of E and B into the expression for s~:
  - Multiply the electric field (E) and magnetic field (B) vectors together.
  - Divide the result by μ₀, which is a constant equal to 4π × 10⁻⁷ T·m/A.
  - The resulting value will give us the electromagnetic energy flux (s) at the surface of the cable.
In Conclusion, By evaluating the electric field and magnetic field at the surface of the long transmission cable, we can use the expression s~ = (1/μ₀) * (E × B) to find the electromagnetic energy flux. This flux represents the rate at which energy is flowing through the cable's surface due to the current.

Considering the fact that we ave been given an angle of inclination here, we best use it! That means that the velocity of 23 m/s is actually NOT the velocity we need; I tell my students that it is a "blanket" velocity but is not accurate in either the x or the y dimension of parabolic motion. In order to find the actual velocity in the dimension in which we are working, which is the y-dimension, we use the formula:

\(v_{0y}=v_0sin\theta\) and filling in:

\(v_{0y}=23sin(25)\) which gives us an upwards velocity of 9.7 m/s. So here's what we have to work with in its entirety:

\(v_{0y}=9.7m/s\)

a = -9.8 m/s/s

t = 2.8 seconds

Δx = ?? m

The one-dimensional motion equation that utilizes all of these variables is

Δx = \(v_0t+\frac{1}{2}at^2\) and filling in:

Δx = \(9.7(2.8)+\frac{1}{2}(-9.8)(2.8)^2\) I am going to do the math according to the correct rules of significant digits, so to the left of the + sign and to 2 sig fig, we have

Δx = 27 + \(\frac{1}{2}(-9.8)(2.8)^2\) and then to the right of the + sign and to 2 significant digits we have

Δx = 27 - 38 so

Δx = -11 meters. Now, we all know that distance is not a negative value, but what this negative number tells us is that the ball fell 11 meters BELOW the point from which it was kicked, which is the same thing as being kicked from a building that is 11 meters high.

Yes, descending intervals are calculated differently from ascending ones.

When calculating ascending intervals, you start with the lower note and count the number of letter names and accidentals to reach the higher note. However, when calculating descending intervals, you start with the higher note and count backward the number of letter names and accidentals to reach the lower note. This is because the direction of the interval affects the size of the interval. For example, a major third ascending from C to E is made up of four semitones, while a major third descending from E to C is made up of three semitones.

The minus 12000 N force acts on the 1800 kg object for 1.95 seconds in order to bring it to a stop from an initial velocity of 13 m/s.

Stationary refers to a state of rest or lack of motion.

We can use the following kinematic equation to solve for the time (t) that the force acts on the object:

vf = vi + at

Where

Using Newton's second law, we can find the acceleration (a) of the object:

F = ma

Where

a = F/m = -12000 N / 1800 kg = -6.67 m/s^2 (the negative sign indicates that the acceleration is in the opposite direction of the force)

Substituting the values into the kinematic equation:

0 = 13 m/s + (-6.67 m/s^2) × t

Solving for t:

t = 13 m/s / 6.67 m/s^2 = 1.95 s

Therefore, the minus 12000 N force acts on the 1800 kg object for 1.95 seconds in order to bring it to a stop from an initial velocity of 13 m/s.

Explanation:

Acceleration is your changing Velocity. An object that is ACCELERATING is experiencing a change in velocity. usually positive. if an object such as a car reduces velocity, it is called deceleration

The acceleration of the car at the top of the hill is 6.6 m/s²

acceleration: the rate at which the speed and direction of a moving object vary over time. A point or object going straight ahead is accelerated when it accelerates or decelerates. Even if the speed is constant, motion on a circle accelerates because the direction is always shifting.

The third kinematic equation is applied to determine the car's tangential acceleration, as illustrated below: v2 = u2 + 2as, where a represents the vehicle's acceleration.

2x50 a = -5.25 m/s²;

2as = v² - u² a

= v²-u² / 2s

a = 102 - 252

At the summit of the hill, the car's centripetal acceleration is given as ac=v²/r

ac=10²/25

ac=4 m/s2.

At the summit of the hill, the car's net acceleration is computed as follows: a net = a2 + ac

a net = (-5.25)2 + 42

Suppose you walk across a carpet with socks on your feet. When you touch a metal door handle, you feel a shock because, c. Excess negative charges build up in your body while walking across the carpet, then jump when attracted to the positive charges in the door handle.

When you walk across a carpet with socks on your feet, the friction between the carpet and your socks causes the transfer of electrons. Electrons are negatively charged particles. As you move, the carpet rubs against your socks, stripping some electrons from the atoms in the carpet and transferring them to your socks. This results in your body gaining an excess of negative charges.

The metal door handle, on the other hand, contains positive charges. When you touch the metal door handle, there is a sudden flow of electrons from your body to the door handle. This movement of electrons is known as an electric discharge or a static shock. The excess negative charges in your body are attracted to the positive charges in the door handle, and this attraction causes the sudden discharge of electrons, resulting in the shock that you feel.

It's important to note that the shock occurs due to the difference in charges between your body and the metal door handle. The friction between your socks and the carpet allows for the buildup of static electricity, and the shock is a result of the equalization of charges when you touch the metal object. Therefore, Option E is correct.

To calculate the magnitude of the force F, we can use Newton's second law of motion, which states that the net force acting on an object is equal to its mass multiplied by its acceleration.

1. Force F: The force F can be broken down into its horizontal and vertical components. The horizontal component of the force F can be calculated using the formula F_horizontal = F * cos(20°). Since the force is being applied to the right, the horizontal component will be positive.

2. Frictional force: The frictional force can be calculated using the formula f_friction = μ * N, where μ is the coefficient of kinetic friction and N is the normal force. In this case, the frictional force is given as 3 N.

3. Normal force: The normal force is the force exerted by the surface on the crate perpendicular to the surface. In this case, the normal force is equal to the weight of the crate since it is on a horizontal surface. The weight can be calculated as the mass of the crate multiplied by the acceleration due to gravity (9.8 m/s^2).

4. Acceleration of the crate: The net force acting on the crate is the force F_horizontal minus the frictional force. The net force divided by the mass of the crate will give us the acceleration of the crate.

To draw a labeled free-body diagram, we need to include the following forces:

- Force F: labeled as F and shown in the direction of the force at an angle of 20° to the horizontal.

- Weight of the crate: labeled as mg and shown downward.

- Normal force: labeled as N and shown perpendicular to the surface.

- Frictional force: labeled as f_friction and shown opposite to the direction of motion.

Please note that without specific numerical values for the force F, it is not possible to calculate the exact magnitudes of the forces and acceleration. The provided information allows us to set up the equations but requires specific values for the force F to find the solution.

The breaking of chemical bonds can either absorb or release energy, depending on the type of chemical reaction. Some chemical reactions release energy when bonds are broken, while others absorb energy. So the correct answer is option: 4.

In exothermic reactions, the energy released by the breaking of chemical bonds is greater than the energy required to break the bonds. Therefore, the excess energy is released in the form of heat, light, or sound.

In endothermic reactions, the energy required to break the bonds is greater than the energy released. Therefore, energy must be absorbed from the surroundings in order to break the bonds. Correct option is 4.

In order to reach the maximum height of 2 meters, Kangaroo should jump with an initial speed of 6.26 m/s.

The three equations of motion are -

first law → v = u +at

second law → S = ut + 1/2 at²

Third law → v² - u² = 2aS

Given is a kangaroo who jumped 2 meters high.

Assume that the kangaroo jumped with an initial velocity of 'u' m/s.

The maximum height achieved is 2 meters.

Acceleration due to gravity will be -9.8 m/s²

At maximum height, the velocity will be zero. Therefore, the final velocity 'v' will be zero. Using third law →

v² - u² = 2aS

- u² = - 2gS  

u² = 2gS

u² = 2 x 9.8 x 2

u² = 39.2

u = 6.26 m/s

Therefore, in order to reach the maximum height of 2 meters, Kangaroo should jump with an initial speed of 6.26 m/s.

Meiosis is divided into two main phases, each with its own set of subphases:

1 Meiosis I:

a. Prophase I: This is the longest and most complex phase of meiosis. During this phase, homologous chromosomes pair up and form bivalents, and crossing over occurs between the homologous chromosomes. The nuclear envelope breaks down, and spindle fibers form from the centrioles at opposite poles of the cell.

b. Metaphase I: During this phase, the homologous chromosomes line up along the metaphase plate, with one chromosome from each homologous pair facing each pole of the cell.

c. Anaphase I: During this phase, the spindle fibers contract and pull the homologous chromosomes towards opposite poles of the cell.

d. Telophase I: During this phase, the chromosomes reach the poles of the cell and the nuclear envelope reforms around each set of chromosomes. The cell then undergoes cytokinesis, resulting in two daughter cells.

2. Meiosis II:

a. Prophase II: During this phase, the nuclear envelope breaks down, and spindle fibers form from the centrioles at opposite poles of the cell.

b. Metaphase II: During this phase, the chromosomes line up along the metaphase plate, with sister chromatids facing opposite poles of the cell.

c. Anaphase II: During this phase, the spindle fibers contract and pull the sister chromatids towards opposite poles of the cell.

d. Telophase II: During this phase, the chromosomes reach the poles of the cell and the nuclear envelope reforms around each set of chromosomes. The cell then undergoes cytokinesis, resulting in four haploid daughter cells.
