The final speed is

The time taken is t = 3.3 s

We have to find the force.

According to Newton's second law, the formula to calculate force is

Substituting the values, the force will be

Thus, the force is 349363.63 N

Answer:

kgm/s(-1)

Explanation:

the units of momentum will be the product of the units of mass and velocity. Mass is measured in kg and velocity in ms-1, therefore, the SI unit of momentum will be kgm/s(-1).

The minimum radius of the circle so that the acceleration at this point will not exceed 4.00 is 2304 m, and the apparent weight of the pilot at the lowest point of the pullout is 272.6 N.

The equation for centripetal acceleration is:

a = (v²)/r, where a is the centripetal acceleration, v is the velocity, and r is the radius of the circle.

The equation can be rearranged to solve for the radius of the circle,

r = (v²)/a.

Plugging in the given values, we get:

r = (96)² / 4.00g

r = 2304 m.

The equation for the apparent weight of the pilot is

\(w_{app}\) = mg - m* \(a_{centripetal}\), where \(w_{app}\) is the apparent weight, m is the mass of the pilot, g is the acceleration due to gravity, and \(a_{centripetal}\) is the centripetal acceleration.

Plugging in the given values, we get \(w_{app}\) = (47.0)(9.8) - (47.0)(4) = 272.6 N.

Therefore, the minimum radius of the circle is 2304 m, and the apparent weight of the pilot is 272.6 N.

If an m×n matrix A has a pivot position in every row, then the equation Ax = b has a unique solution for each b in ℝᵐ.

Let's consider an m×n matrix A, where each row contains a pivot position. This implies that each row of the matrix has a leading entry, which is the leftmost nonzero entry in that row.

To determine the solution for the equation Ax = b, we can use the concept of row operations. By performing row operations on matrix A, we can transform it into an equivalent row-echelon form or reduced row-echelon form.

If matrix A is in row-echelon form or reduced row-echelon form and has a pivot position in every row, it means that each row corresponds to a linear equation with a unique leading variable. This guarantees that the system of equations represented by the matrix has a unique solution.

In other words, the presence of a pivot position in every row ensures that each variable in the system of equations has a unique coefficient. Consequently, for any vector b in ℝᵐ, there exists a unique solution x that satisfies the equation Ax = b.

Hence, if an m×n matrix A has a pivot position in every row, the equation Ax = b has a unique solution for each b in ℝᵐ.

To determine the magnitude of the average force of friction acting on the ice skater while she slows to a stop, we can use the following equation: Force = (mass * change in velocity) / time. The magnitude of the average force of friction acting on the ice skater while she slows to a stop is approximately 16.83 N.

First, we find the change in velocity, which is the final velocity minus the initial velocity. Since she comes to a stop, the final velocity is 0 m/s. So the change in velocity is 0 - 2.45 m/s = -2.45 m/s.
Next, we plug the values into the equation:
Force = (51.0 kg * -2.45 m/s) / 7.45 s
Force = -125.45 kg·m/s / 7.45 s
Force ≈ -16.83 N

The moment of inertia will increase by a factor of 16. Hence, the answer is D) 16.

The moment of inertia of a uniform thin disk of mass M and radius R is given by the formula:

I = (1/2)MR^2

If the diameter of the disk is doubled, its radius will also be doubled. Let's assume that the original disk has a radius R and the new disk has a radius 2R. The mass of the new disk will be four times the mass of the original disk because the volume (and hence the mass) of a disk is proportional to the square of its radius. Since the thickness of the disks is the same, the density of the material will also be the same.

Therefore, the moment of inertia of the new disk can be calculated as follows:

I_new = (1/2)(4M)(2R)^2 = 8MR^2

The moment of inertia of the original disk is:

I_original = (1/2)M(R)^2

So the ratio of the moment of inertia of the new disk to that of the original disk is:

I_new/I_original = (8MR^2) / [(1/2)M(R)^2] = 16

Therefore, the moment of inertia will increase by a factor of 16. Hence, the answer is D) 16.

All of the major planets (Mercury, Venus, Mars, Jupiter, Saturn, Uranus, and Neptune) appear to undergo retrograde motion as viewed from the Earth.

Retrograde motion is the apparent backward movement of a planet in the sky due to the difference in the speed of Earth's orbit compared to the other planets. Because Earth's orbit is faster than the outer planets (Mars, Jupiter, Saturn, Uranus, and Neptune), it overtakes them, causing them to appear to move backward in the sky.

Similarly, because Earth's orbit is slower than the inner planets (Mercury and Venus), they appear to move backward in the sky as they overtake Earth.

Therefore, all of the major planets appear to undergo retrograde motion as viewed from the Earth.

The angular momentum of a system is constant if the total linear momentum of the system is zero.

The main answer is that if the total linear momentum of a system of particles is zero, the angular momentum of the system remains constant regardless of the choice of origin. Angular momentum is a measure of rotational motion and depends on the distribution of mass and velocity within the system

When the total linear momentum is zero, it implies that the system's center of mass is stationary or moving at a constant velocity. In such cases, the system's angular momentum is independent of the origin chosen for calculations.

Evolution is the process by which species of living organisms change over generations through a combination of genetic variation, mutation, natural selection, and genetic drift. The theory of evolution explains how species have changed over time to become the diverse forms that exist today, and provides a scientific explanation for the relatedness of different species.

Answer:

(2) the work required to move the electron is 4.8 x 10⁻¹⁹ J.

Explanation:

Given;

potential difference, V = 3.00 volts

charge of electron, q = 1.6 x 10⁻¹⁹ C

The work required to move an electron is calculated as;

W = Vq

The converted energy of  is the thermal energy created by the friction during his descent. The thermal energy is created by friction during his descent is 404 J .

Given information:

Mass of Justin = 55 kg

Height of water slide = 8 m

Speed at the bottom = 12m/s

Mechanical energy (kinetic or potential energy) is the energy of an object in motion or the energy stored by an object in its position. Mechanical energy is also the engine of renewable energies.

Now,

the total mechanical energy is:

   E(i) = U = mgh

⇒ E(i) = 55×9.81×8

⇒ 4004 J

Kinetic energy is the energy that an object possesses due to its motion. If we want to accelerate an object, we must apply a force. The application of force forces us to work. After the work has been done, the energy has been transferred to the object and the object will move at a new constant speed.

And, the kinetic energy :

   E(f) = K = (1/2) mv²

⇒ E(f) = 0.50 × 50 × 12

⇒ E(f) = 3600 J

So, the energy lost by the Justin:

   ΔE = E(i) -E(j)

⇒ ΔE = 4004 J - 3600 J

⇒ ΔE = 404 J

Hence, this converted energy of  is the thermal energy created by the friction during his descent.
