Answer:

The gravitational potential energy of that rock is 174371.4 J.

Explanation:

Given

To determine

We need to find the gravitational potential energy of the rock

We know that the potential energy of a body is termed as the stored energy due to its position.

One kind of energy comes from Earth's gravity — Gravitational potential energy (GPE).

Gravitational potential energy (GPE) can be determined using the formula

\(GPE = mgh\)

where

now substituting m = 59.31, h = 300 and g = 9.8

\(GPE = mgh\)

         \(=59.31\times 9.8\times 300\)

         \(=174371.4\) J

Therefore, the gravitational potential energy of that rock is 174371.4 J.

A 10-kg weight is suspended in air by strong cable, then there is no work done in suspending the weight as the weight suspended in the air  does not move or experience any form of displacement.

Only Mass = 10 kg is given and no displacement so there is no work done as Work done = force * distance

In Physics, work done is defined as the amount of energy transferred when body is moved over a distance due to the action of external force.

The work done by a force is defined as the product of component of force in the direction of displacement and magnitude of this displacement.

The closest answer choice is d) -2.08 x 10⁻⁴.Because the transverse strain is approximately -0.00375.

The transverse strain can be calculated using the formula: transverse strain = -Poisson's ratio * axial strain.

Given:

Length of the metal bar (L) = 1.5 ft

Axial strain (ε) = 0.015 in./in.

Poisson's ratio (ν) = 0.25

To determine the transverse strain, we can substitute the given values into the formula:

Transverse strain = -0.25 * 0.015 = -0.00375

The transverse strain is approximately -0.00375.

Therefore, the closest answer choice is d) -2.08 x 10⁻⁴.

The statement is false. Because there is more mechanical linkage created between the bodies' uneven contact surfaces in solid friction, it always outweighs fluid friction.

These solids' uneven surfaces deform when they move, requiring comparatively greater force than fluid. As a result, the assertion is untrue. Friction is a force that prevents two solid objects from rolling or sliding over one another. Although frictional forces, such the traction required to walk without slipping, may be advantageous, they can provide a significant amount of resistance to motion. Frictional force keeps our feet firmly planted on the ground as we walk on the ground or a floor. We tend to slip on slippery surfaces like ice because there is less friction there.

fluid moving through a horizontal pipe P1 + ½ρv12 = P2 + ½ρv22. The pressure will depend on the fluid's speed if it is flowing frictionlessly through a horizontal pipe with a variable cross-sectional area as a liquid (or a gas that is not being compressed).

The fluid's velocity and cross-sectional area before and after the pipe's constriction can be compared using the continuity concept.

ρ1A1v1 = ρ2A2v

Moreover, we may link the fluid's pressure and velocity before and after the constriction using Bernoulli's equation:

P1 + 1/2ρ1v1² = P2 + 1/2ρ2v2²

v2 = (ρ1/ρ2) × (A1/A2) × v1

P1 + 1/2ρ1v1² = P2 + 1/2ρ1(A1/A2)²(v1)²

Solving for v1, we get:

v1 = sqrt(2(P1 - P2)/ρ1(1 - (A1/A2)²))

v1 = sqrt(2(7980 - 5985)/(821)(1 - (0.618/0.223)^2)) = 2.117 m/s.

Triplind s means multiplying it by 3. Since it's an equation we should multiply both sides by the same number

Let k be the number we should multiply by r

●k* r = (3s)^2 / t^2

●k* r = 9s^2 /t^2

We have multiplied s^2 by 9 so we should do the same for r.

The thermal transfers via "Conduction and Radiation"

Explanation:

Because, Convection is the transfer of thermal energy by particles moving through a fluid. Thermal energy is always transferred from an area with a higher temperature to an area with a lower temperature.

Moving particles transfers the thermal energy through a fluid by forming convection currents.

It transfers ( thermal ) heat energy to a food's surface via convection and radiation. So that, the heat energy on the food's surface, then it spreads via "conduction" towards the food's center.

When a solid object rotates, a point close to the center takes less time to complete one revolution compared to a point near the outer edge.

When a solid object rotates, each point on the object moves in a circular path around the center of rotation. The time taken for a point to complete one revolution depends on its distance from the center. The distance between a point and the center is directly related to the radius of the object.

To understand the time difference, consider a point near the center and another point near the outer edge of the rotating object. The point near the center has a smaller radius, meaning it has a shorter distance to travel to complete one revolution. As a result, it covers this distance in less time compared to the point near the outer edge, which has a larger radius and a longer distance to travel.

Mathematically, the relationship between the time taken for a point to complete one revolution (T) and its radius (r) can be expressed as T ∝ r. This means that the time taken is directly proportional to the radius. Therefore, a point closer to the center takes less time to go around once compared to a point near the outer edge, as the radius decreases as we move towards the center.

The critical angle of the transparent material is 35.3 degrees.

The critical angle is the angle of incidence at which the angle of refraction is 90 degrees. In this case, the angle of refraction is 32 degrees. Therefore, the critical angle is calculated as follows:

sin(critical angle) = sin(90 degrees) / sin(angle of refraction)

sin(critical angle) = 1 / sin(32 degrees)

sin(critical angle) = 0.574

critical angle = arcsin(0.574)

critical angle = 35.3 degrees

Complete Question

In a ballistics test, a 21 g bullet traveling horizontally at 1200 m/s goes through a 35-cm-thick 300 kg stationary target and emerges with a speed of 950 m/s . The target is free to slide on a smooth horizontal surface.

a

How long is the bullet in the target? ____ s

b

What average force does the bullet exert on the target? _____ N

c

What is the target's speed just after the bullet emerges? _____ m/s

Answer:

a

\(t =3.256*10^{-4} \ s\)

b

\(F = 16124 \ N\)  

c

\(v_1 = 0.0175 \ m/s\)

Explanation:

From the question we are told that

  The mass of the bullet is  \(m = 21 \ g = 0.021 \ kg\)

   The horizontal speed is \(u =1200 \ m/s\)

   The thickness is  \(s = 35 \ cm = 0.35 \ m\)

   The mass of the block is  \(m_1 = 300 \ kg\)

   The emerging speed is  \(v = 950 \ m/s\)    

Generally from kinematic equation

    \(v^2 = u^2 + 2as\)

So

      \(a = \frac{v^2 - u^2}{2s}\)

=>  \(a = \frac{ 950^2 - 1200^2}{2 * 0.35}\)

=>   \(a = -767857.14 \ m/s^2\)

Gnerally the time taken is mathematically represented as

      \(t = \frac{ v- u}{a}\)

=>   \(t = \frac{ 950 - 1200}{-767857.14}\)

=>   \(t =3.256*10^{-4} \ s\)

Generally from law of momentum conservation we

     \(m *u + m_1 * u_1 = m * v + m_1 * v_1\)

\(u_1\)  is the velocity of the block at rest which is  \(u_1 = 0 \ m/s\)

=> \(0.021 *1200 + 300 * 0 = 0.021 * 950 + 300 * v_1\)

=> \(v_1 = 0.0175 \ m/s\)

Generally the force is mathematically represented as

    \(F = \frac{m_1 * v_1 }{t}\)

=> \(F = \frac{300 * 0.0175 }{3.256 *10^{-4}}\)

=> \(F = 16124 \ N\)    

Answer:

The value is  \(t = 18.6 s\)

Explanation:

From the question we are told that

     The average acceleration of the bicycle is \(v = -0.44 \ m/s^2\)

      The initial forward velocity is  \(u = 8.2 \ m/s\)

Generally from kinematic equations we have that

      \(v = u + at\)

Here v is the final velocity of the bicycle and the value is v = 0 m/s

So

      \(0 = 8.2 + (-0.44)t\)

=>    t = 18.6 s

the answer is definitely A.
