Acceleration is greatest for a satellite in an elliptical orbit when it is closest to Earth.

According to Kepler's second law, a satellite in an elliptical orbit sweeps out equal areas in equal time intervals. This means that the satellite covers more distance in a given time when it is closer to Earth.

The acceleration of a satellite in orbit is determined by the gravitational force exerted by Earth. Since gravitational force decreases with distance, the satellite experiences a stronger gravitational force when it is closer to Earth. As a result, the acceleration of the satellite is greatest when it is closest to Earth.

Therefore, the statement "Acceleration is greatest for a satellite in an elliptical orbit when it is closest to Earth" is correct.

To prevent a 60.0 kg woman from getting her feet wet while standing on a slab, the minimum volume required is 60.0 liters. This assumes that the woman's body is completely submerged when standing on the slab, and that the density of the woman is close to that of water.

The volume of an object can be calculated using the formula:

\(\[ V = \frac{m}{\rho} \]\) where V is the volume, m is the mass and \(\(\rho\)\) is the density. In this case, the woman's mass is given as 60.0 kg. Since she needs to float on the water without getting her feet wet, her density must be equal to or less than the density of water, which is approximately 1000 kg/m³. Therefore, the volume required is:

\(\[ V = \frac{60.0\, \text{kg}}{1000\, \text{kg/m³}} = 0.06\, \text{m³} = 60.0\, \text{liters} \]\)

The material that falls back to the lunar surface after being blasted out by the impact of a space object is called "ejecta."

When a space object, such as a meteoroid or asteroid, impacts the lunar surface, it excavates and ejects material from the Moon. This material is referred to as "ejecta." Ejecta consists of a mixture of lunar soil, rock fragments, and vaporized debris that was forcibly expelled from the impact site. As the ejecta is launched into space, it follows a ballistic trajectory, influenced by the Moon's gravity, before eventually falling back to the lunar surface. The composition and distribution of the ejecta provide valuable insights into the impact event, including the size and velocity of the impacting object, and can also contribute to the accumulation of regolith and the formation of impact craters on the Moon.

Answer: the answer given below

(a) Explanation: The impulse on an object is given by the change in momentum of the object. Before the collision, the bullet has momentum p1 = mv0 and the brick has momentum p2 = 0, since it is stationary. After the collision, the combined bullet-brick system has momentum p3.

Conservation of momentum requires that the total momentum before the collision is equal to the total momentum after the collision:

p1 + p2 = p3

mv0 + 0 = (m + M)V

where V is the velocity of the combined bullet-brick system after the collision. Solving for V, we get:

V = (mv0) / (m + M)

The impulse on the bullet during the collision is equal to the change in momentum of the bullet:

J_bullet = p3 - p1 = (m + M)V - mv0

Substituting the expression for V we found earlier:

J_bullet = (m + M)(mv0) / (m + M) - mv0 = 0

Therefore, the impulse on the bullet is zero during the collision.

On the other hand, the impulse on the brick during the collision is:

J_brick = p3 - p2 = (m + M)V - 0 = (m + M)(mv0) / (m + M) = mv0

Therefore, the magnitude of the impulse acting on the brick is equal to the initial momentum of the bullet, mv0, and it is in the same direction as the initial velocity of the bullet.

In summary, during the collision of the bullet and the brick, the impulse acting on the bullet is zero, while the impulse acting on the brick is mv0 in the direction of the initial velocity of the bullet.

(b) We can use the principle of conservation of momentum to solve for the velocity of the brick-bullet combination just after the collision. The total momentum of the system (bullet, brick, and Earth) is conserved before and after the collision. Initially, only the bullet has momentum, which is given by p1 = m*v0, and the momentum of the brick and Earth is zero. After the collision, the bullet becomes embedded in the brick, and the combined system of the brick-bullet has momentum p2. Since the momentum of the Earth is negligible compared to that of the bullet and brick, we can treat the system as closed and apply conservation of momentum:

p1 = p2

m*v0 = (M + m)*v

where v is the velocity of the combined system just after the collision.

Solving for v, we get:

v = (m*v0) / (M + m)

Therefore, the magnitude of the velocity of the brick-bullet combination just after the collision is:

|v| = |(m*v0) / (M + m)|

The direction of the velocity is upward, as the system swings up after the collision due to the conservation of momentum.

(c) The initial kinetic energy of the system is the kinetic energy of the bullet just before the collision, which is given by:

KE1 = (1/2)mv0^2

The final kinetic energy of the system is the kinetic energy of the combined brick-bullet system just after the collision, which is given by:

KE2 = (1/2)*(M + m)*v^2

Substituting the expression we found for v:

KE2 = (1/2)(M + m)[(mv0) / (M + m)]^2

KE2 = (1/2)(m*v0^2) / (1 + M/m)

The ratio of the final kinetic energy to the initial kinetic energy is:

KE2 / KE1 = [(1/2)(mv0^2) / (1 + M/m)] / [(1/2)mv0^2]

KE2 / KE1 = 1 / (1 + M/m)

Therefore, the ratio of the final kinetic energy of the brick-bullet combination immediately after the collision to the initial kinetic energy of the brick-bullet combination is:

KE2 / KE1 = 1 / (1 + M/m)

(d)To determine the maximum vertical position reached by the brick-bullet combination, we can use conservation of energy, assuming there is no energy loss due to friction or other dissipative forces. At the maximum height, the kinetic energy of the system is zero, and all the initial kinetic energy has been converted to potential energy due to the height above the initial position.

The initial total energy of the system is the sum of the initial kinetic energy of the bullet and the gravitational potential energy of the brick:

E1 = (1/2)mv0^2 + Mgh1

where h1 is the initial height of the brick above the ground, and g is the acceleration due to gravity.

At the maximum height, the final total energy of the system is the potential energy due to the height above the ground:

E2 = (M + m)gh2

where h2 is the maximum height reached by the brick-bullet combination above the initial position.

Since there is no energy loss, we can set the initial energy equal to the final energy:

E1 = E2

Substituting the expressions for E1 and E2 and solving for h2, we get:

(M + m)gh2 = (1/2)mv0^2 + Mgh1

h2 = [(1/2)mv0^2 + Mgh1] / [(M + m)*g]

Simplifying, we get:

h2 = (1/2)v0^2 / g + h1(M/m) / (1 + M/m)

Therefore, the maximum vertical position above the initial position reached by the brick-bullet combination is:

h2 = (1/2)v0^2 / g + h1(M/m) / (1 + M/m)

If a 1.50-kg mass is acted upon by a force of 16.0 N applied at an angle of 60° above the horizontal. The acceleration of the mass is approximately 5.33 m/s². Therefore, the correct option is (B) 5.33 m/s².

The given force applied at an angle of 60° is 16 N. The mass of the object is 1.50 kg. We need to calculate the acceleration of the mass. The force is resolved into two components. One component is parallel to the surface and another one is perpendicular to the surface.

We can calculate the parallel and perpendicular components as:

F⊥= F sin θ = 16 sin 60° = 13.86 N.

F|| = F cos θ = 16 cos 60° = 8 N.

Here, F⊥ is the perpendicular force and F|| is the parallel force. So, the perpendicular force acting on the mass is 13.86 N and the parallel force acting on the mass is 8 N. Now we can calculate the acceleration of the mass as:

Net force acting on the object, F = F|| = 8 N. Using Newton's second law of motion, we have:

ma = F ⇒ a = F/m.

Using this value of F and m, we get the acceleration as a = 8 N/1.50 kg ≈ 5.33 m/s². Hence, B is the correct option.

When you change the thickness of the wire in a circuit, option B. the resistance (R) and current (I) will also change, but the voltage (V) will remain constant.

The resistance of a wire is directly proportional to its length and inversely proportional to its cross-sectional area (thickness). As the thickness of the wire changes, the cross-sectional area changes, which in turn affects the resistance. Thicker wires have a larger cross-sectional area, resulting in lower resistance, while thinner wires have a smaller cross-sectional area, resulting in higher resistance. Therefore, changing the thickness of the wire will cause a change in resistance.

According to Ohm's Law (V = IR), the voltage (V) in a circuit is equal to the product of the current (I) and the resistance (R). If the voltage is kept constant, and the resistance changes due to the thickness of the wire, the current will also change to maintain the relationship defined by Ohm's Law. When the resistance increases, the current decreases, and vice versa.

However, it's important to note that changing the thickness of the wire will not directly affect the voltage. The voltage in a circuit is determined by the power source or the potential difference applied across the circuit and is independent of the wire thickness. As long as the voltage source remains constant, the voltage across the circuit will remain constant regardless of the wire thickness. Therefore, the correct answer is option B.

The time taken for the coffee to cool from 93°C to 73°C is approximately 36.1 minutes.

The cooling law is given by:

$$\frac{dQ}{dt}=-k(T-T_0)$$

where Q is the heat in the object, t is the time taken, T is the temperature of the object at time t, T0 is the temperature of the environment and k is a constant known as the cooling constant.

We need to find the time it takes for the coffee to reach a drinking temperature of 73°C given that its initial temperature is 93°C.

Therefore, we need to find the time it takes for the coffee to cool down from 93°C to 73°C when placed in a room temperature of 18°C.

Let’s assume that the heat energy that is lost by the coffee is equal to the heat energy gained by the environment. We can express this as:

dQ = - dQ where dQ is the heat energy gained by the environment.

We can substitute dQ with C(T-T0) where C is the specific heat capacity of the object.

We can rearrange the equation as follows:

$$-\frac{dQ}{dt}=k(T-T_0)$$

$$-\frac{d}{dt}C(T-T_0)=k(T-T_0)$$

$$\frac{d}{dt}T=-k(T-T_0)$$

The differential equation above can be solved using separation of variables as follows:

$$\frac{d}{dt}\ln(T-T_0)=-k$$

$$\ln(T-T_0)=-kt+c_1$$

$$T-T_0=e^{-kt+c_1}$$

$$T=T_0+Ce^{-kt}$$

where C = e^(c1).

We can now use the values given to find the specific value of C which is the temperature difference when t=0, that is, the temperature difference between the initial temperature of the coffee and the room temperature.

$$T=T_0+Ce^{-kt}$$

$$73=18+C\cdot e^{-0.09t}$$

$$55=C\cdot e^{-0.09t}$$

$$C=55e^{0.09t}$$

$$T=18+55e^{0.09t}$$

We can now solve for the value of t when T=93 as follows:

$$93=18+55e^{0.09t}$$

$$e^{0.09t}=\frac{93-18}{55}$$

$$e^{0.09t}=1.3636$$

$$t=\frac{\ln(1.3636)}{0.09}$$
