In an experiment in space, one proton is held fixed
and another proton is released from rest a distance
of 2.00 mm away.
What is the initial acceleration of the proton after it is released?

Gravity is the only force that is active. The overall mechanical energy is preserved since it is an inner or conservative force. As a result, each location has the 100 J of initial mechanical energy. So, 50 J is the KE for A.

The KE is 50 J because the PE at the exact same stairstep is Fifty J (C) (D).

The PE is 0 J at zero height (F and I). As a result, there is 100 J of velocity just at bottom of the hill (G and J).

The velocity may be calculated as 7.07 m/s for B and E as well as 10 m/s for H and K using the formula KE = 0.5*m*v2.

The answers provided here for the speed numbers are based on the assumption that 100% of the ball's kinetic energy is present as translational kinetic energy. The kinetic energy really would take some of the form of rotating kinetic energy. The real speed figures would thus be a little bit lower than those reported.

The net charge within the sphere's surface is 2.36 x 10^-7 C and it can be deduced that the charge within the spherical shell is positively charged and uniformly distributed on its surface.

(a) To ascertain the net charge enclosed within the boundaries of the spherical shell of radius 0.730 meters, we must delve into the intricacies of the electric field and its correlation with the charge distribution on a conductor.

The electric field on the surface of a conductor can be mathematically represented as E = kσ, where k stands for the Coulomb constant and σ symbolizes the surface charge density.

The surface area of a spherical shell can be calculated as 4π[tex]r^2[/tex], where r signifies the radius of the sphere. By fusing these two equations, we can determine the surface charge density as follows:

σ = E / (k) = (875 n/C) / (9 x 10^9 Nm^2/C^2) = 9.72 x 10^-10 C/m^2

The charge contained within the sphere can then be computed as:

Q = σ * 4πr^2 = (9.72 x 10^-10 C/m^2) * 4π * (0.730 m)^2 = 2.36 x 10^-7 C

(b) The electric field, exhibiting a radially inward direction, implies that the charge within the spherical shell is positively charged.

The proportionality between the electric field's magnitude and the net charge within the spherical shell suggests that the charge is distributed uniformly on the surface of the sphere.

In conclusion, it can be deduced that the charge within the spherical shell is positively charged and uniformly distributed on its surface.

Answer:

The distance traveled by train in 12 seconds is 66.72 meters.

Explanation:

The acceleration rate given is in meters per second squared, so we need to convert the velocity of the train to meters per second.

20 km/hr = (20 x 1000)/(60 x 60) = 5.56 m/s

Now we can use the formula for displacement with constant acceleration:

d = v₀t + 0.5at²

where

v₀ = initial velocity = 5.56 m/s

t = time = 12 s

a = acceleration = 0.5 m/s²

Substituting the values, we get:

d = 5.56 x 12 + 0.5 x 0.5 x 12²

d = 66.72 m

A car is traveling southward as its speed decreases from 18 m/s to 12 m/s have an acceleration that is directed due north.

What is acceleration?

If an object's velocity changes, it is said to have been accelerated. An object's velocity can alter depending on whether it moves faster or slower or in a different direction. A falling apple, the moon orbiting the earth, and a car stopped at a stop sign are a few instances of acceleration. Through these illustrations, we can see that acceleration happens whenever a moving object changes its direction or speed, or both.

The magnitude of the electric field due to the disk at the point x = 15 cm along the x-axis is approximately 2.99 x 10⁶ N/C. Rounded to two significant figures, the answer is 3.0 x 10⁶ N/C.

The magnitude of a physical quantity is a measure of the size of that quantity, and is usually expressed using an appropriate unit of measurement. Magnitude is a way of expressing the size of something without specifying its exact size. For example, when referring to the magnitude of an earthquake, one might say "it was a magnitude 7 earthquake".

To calculate the electric field at a point on the x-axis due to a uniformly charged disk, we can use the formula:

[tex]\mathrm{E = (1/4\pi \p \epsilon_0) \times Q / r^2 \times sin(\theta)}[/tex]

where ε₀ is the permittivity of free space,

Q is the total charge on the disk, r is the distance from the center of the disk to the point where we want to calculate the electric field,

and θ is the angle between the normal to the disk and the line connecting the center of the disk to the point where we want to calculate the electric field.

In this problem, the disk is oriented in the yz-plane, so the normal to the disk is in the x-direction. The distance from the center of the disk to the point where we want to calculate the electric field is 15 cm.

The angle θ is the angle between the normal to the disk and the line connecting the center of the disk to the point where we want to calculate the electric field.

Since the disk is centered at the origin, the line connecting the center of the disk to the point on the x-axis is also in the x-direction, so θ = 0.

We can therefore simplify the formula to:

[tex]\mathrm{E = (1/4\pi \p \epsilon_0) \times Q / r^2 }[/tex]

Substituting the given values, we get:

[tex]\mathrm{E = (1/4\pi \p \epsilon_0) \times (3\mu C) / (0.15)^2 }[/tex]

We can calculate the value of 1/4πε₀ as 9 so:

[tex]\mathrm{E = (9.0 \times 10^9 \ N \cdot m^2/C^2) \times (3\mu C) / (0.15)^2 }[/tex]

E = 2.99 x 10⁶ N/C

Therefore, the magnitude of the electric field due to the disk at the point x = 15 cm along the x-axis is approximately 2.99 x 10⁶ N/C. Rounded to two significant figures, the answer is 3.0 x 10⁶ N/C.

The velocity of the ball is 19.6 m/s and when the ball lands, it is moving at a speed of 77.134 m/s.

All objects with mass are subject to gravity, which is a fundamental force of nature. It is the force that pulls everything toward the core of a planet or other entity.

(a) The equation can be used to determine the velocity of a dropped ball.

v = v0 + a * t

where a is the acceleration caused by gravity (9.8 m/s2), v0 is the beginning velocity (0 in this case because the ball is dropped from rest), and t is the amount of time that has passed.

Therefore, if t = 2 seconds, the ball's velocity at that time would be:

v = 0 + 9.8 * 2 = 19.6 m/s

(b) The ball's final velocity is identical to its velocity when it lands. The following equation can be used to determine how long it takes the ball to touch the ground:

t = √(2h / a)

where a is the acceleration brought on by gravity (9.8 m/s2) and h is the height (in this case, 300 m) from which the ball is dropped.

Thus, the duration of time required for the ball to touch the ground is:

t = √(2 * 300 / 9.8) = √(600 / 9.8) = √(61.22) = 7.83 s

The formula: can be used to determine the ball's velocity when it lands.

v=v0 + a*t = 0 + 9.8 * 7.83 = 77.134 m/s

The radius of the first null in the diffraction pattern at the moon would be approximately 9.64 mm

The radius of the first null in the diffraction pattern at the moon can be calculated using the formula for diffraction from a circular aperture. The formula for the radius of the first null, or the first dark fringe, is given by:

r = λ × D / a,

where λ is the wavelength of light, D is the distance from the aperture to the screen, and a is the radius of the circular aperture. In the case of diffraction at the moon, the aperture is the diameter of the moon, and the screen is the observer's eye or a detector. The diameter of the moon is approximately 3,476 kilometers, and the distance from the moon to the Earth is approximately 384,400 kilometers. The wavelength of light used for observation can vary, but for visible light, it is typically in the range of 400 to 700 nanometers.

By substituting these values into the formula, we can calculate the radius of the first null in the diffraction pattern at the moon.

Let's assume a wavelength of 550 nm (visible light) and use the average value for the diameter of the moon (3,476 km) as the radius (1,738 km) in the calculation.

r = λ × D / a

= (550 × [tex]10^{-9}[/tex] m) × (384,400 × [tex]10^{3}[/tex] m) / (1,738 × [tex]10^{3}[/tex] m)

Complete question:

Current is defined (mathematically) by the equation I is equal to start fraction delta Q over delta t end fraction (for average current) or I is equal to start fraction dQ over dt end fraction (for instantaneous current, using calculus). Using whichever definition you are comfortable with, when considering current in a wire, this can be stated (conceptually) as which of the following?

A. Current is distance times charge (d times Q) divided by distance times time (d times t).

B. Current is the amount of charge in a wire, divided by the time it takes to fill the wire with charge.

C. Current is the rate at which the total charge within the wire is changing.

D. Current is the rate at which charge passes a certain place in the wire.

To compute [tex]2^3[/tex], the function first calls itself with [tex]n=2,[/tex] which computes[tex]2^2 = 4[/tex]. Then, the function doubles this result to get [tex]2^3 = 8.[/tex]

Here is the pseudo-code for the pow2 function:

function pow2(n):

   if n < 0:

       return -1

   if n == 0:

       return 1

   else:

       prev_power = pow2(n-1)  # Compute 2^(n-1) recursively

       return prev_power * 2   # Double the result to get [tex]2^n[/tex]

The base case for the recursion is when n is 0, in which case the function returns 1 since [tex]2^0 = 1.[/tex]

The function recursively calls itself with smaller values of n until it reaches the base case. The recursive calls build up the power of 2 by doubling the previous power.

The velocity of the balls that rolling directly toward each other. One, of mass 0.25 kg, has a speed of 1.7 m/s; the other has a mass of 0.18 kg and a speed of 2.5 m/s. After the collision, the 0.25 kg ball has reversed its direction and has a speed of 0.10 m/s = 0 (zero)

The linear momentum of a system of interacting objects equals the linear momentum of the system after the interaction if the net force acting on the system of interacting objects is zero.

The equation:

p = mv

Where,

p = momentum

m = mass of the object

v = the velocity of the object.

p₁ = p₂

(mv + mv)₁ = (mv + mv)₂

(0.25 x 1.7) = (0.25 x (-0.10)

v₂ = 0
