The system's momentum and total kinetic energy are different before and after the collision depending on the location of the impact.This henceforth indicates that a net external force is exerted on the system.

In a closed system where no external forces act, the total momentum and total kinetic energy of the system are conserved. This is known as the conservation of momentum and the conservation of energy, respectively.

If external forces act on the system, then the total momentum and total kinetic energy of the system are not conserved. In this case, the net external force can be calculated by the change in momentum over time using Newton's second law, F = Δp/Δt.

To calculate the final velocity after the collision between the two celestial bodies, we need to apply the principle of conservation of momentum. The final velocity will depend on the masses and initial velocities of the bodies.

According to the principle of conservation of momentum, the total momentum before the collision is equal to the total momentum after the collision. The momentum of an object is given by the product of its mass and velocity.

Let's denote the mass of the first celestial body as m1 (55 kg) with a velocity of v1 (565 m/s), and the mass of the second celestial body as m2 (40 kg) with a velocity of v2 (-613 m/s, since it is moving west).

The total momentum before the collision is given by:

Initial momentum = m1 * v1 + m2 * v2

To find the final velocity, we need to equate the initial momentum to the total momentum after the collision:

m1 * v1 + m2 * v2 = (m1 + m2) * vf

Where vf represents the final velocity.

Solving this equation for vf, we get:

vf = (m1 * v1 + m2 * v2) / (m1 + m2)

Substituting the given values, we have:

vf = (55 kg * 565 m/s + 40 kg * -613 m/s) / (55 kg + 40 kg)

vf = (-2905 kg·m/s) / (95 kg)

vf ≈ -30.58 m/s

Therefore, the final velocity after the collision is approximately -30.58 m/s. The negative sign indicates that the final velocity is in the opposite direction of the initial velocities.

The maximum height that the ball will reach is 25 feet. when the ball will reach its maximum height after 1.25 seconds.

The maximum height that the ball will reach can be determined by finding the vertex of the parabola represented by the function

h(t) = 40t - 16t²

The x-coordinate of the vertex can be found using the formula

x = - b / (2a)

where:

a = coefficient of the t² term

b = coefficient of the t term.

Given

a = -16

b = 40

x = -40/(2×(-16))

= 1.25

This means that the ball will reach its maximum height after 1.25 seconds. We need to substitute this value of t into the function to determine the maximum height:

h(1.25) = 40 (1.25) - 16 (1.25)²

= 50 - 25

= 25.

When a liquid vaporizes at its boiling point at a given external pressure, the correct statement that describes the change is that the kinetic energy increases. Option c.

This is because as the liquid is heated to its boiling point, the temperature remains constant until all of the liquid has vaporized. During this phase change, the energy supplied to the liquid is used to break the intermolecular forces between the liquid particles, increasing their kinetic energy and causing them to escape into the gas phase. The entropy of the system also increases, as the liquid molecules are now more disordered in the gas phase than they were in the liquid phase.

The potential energy of the system remains constant during this process, as there is no change in the distance between the particles. Therefore, the correct statement is that the kinetic energy increases when a liquid vaporizes at its boiling point at a given external pressure. Answer option c.

The adopting family that Leilani lived with can be classified as a "fictive kin" family, creating a social bond that mimics biological relationships and provides support similar to biological parents.

Sociologists would classify the adopting family that Leilani lived with as a "fictive kin" family. Fictive kinship refers to a social bond between individuals that mimics the biological relationships of kinship. In this case, the adopting family took on the role of Leilani's parents, providing her with emotional, social, and financial support just like biological parents would.

Fictive kinship is common in many cultures, and it can be formed through a variety of mechanisms such as adoption, godparenting, or even close friendships. The purpose of fictive kinship is to create a sense of belonging and connection within a community, and it often plays a crucial role in providing support to individuals who have lost their biological family members.

In the case of Leilani, the adopting family fulfilled the role of parents, providing her with love and care for the majority of her childhood. While they may not have been biologically related, the bond they formed with Leilani was just as strong as if they were. Thus, sociologists would classify the adopting family as a fictive kin family, demonstrating the importance of these non-biological family structures in society.

The acceleration of the carts and the tension of the cord can be calculated using the formula a = (m1-m2)g/(m1+m2) and T = 2m1a.

The formula for the acceleration of the carts is a = (m1-m2)g/(m1+m2), where m1 and m2 are the masses of the carts and g is the acceleration due to gravity. The formula for the tension of the cord is T = 2m1a, where T is the tension in the cord and a is the acceleration of the carts.

In this problem, since there is no friction, the net force on the system is equal to the tension in the cord. Using these formulas, we can calculate both the acceleration and the tension in the cord. It is important to note that the acceleration will be positive if m1 is greater than m2 and negative if m1 is less than m2. This is because the heavier cart will move down the incline and the lighter cart will move up, causing the system to accelerate.

Where a river flows from an area of hard rock to an area of soft rock, the softer rock may wear away, eventually forming a drop called a waterfall. Thus, the correct option is B.

A waterfall is a river or other body of the water's steep which fall over a rocky ledge into a plunge pool below. Waterfalls are usually also called as cascades. The process of erosion, the wearing away of the earth, plays an important part in the formation of waterfalls in the world.

Waterfalls are generally created when the riverbed changes suddenly from the hard rock to soft rock. Rapids are formed where a fast-flowing river quickly cuts downwards through the waterbed of hard and soft rocks, eroding the soft rock and leaving the hard rocks which are standing above the water surface.

Answer: A Hydrothermal vent

Explanation:

It takes approximately 2.64x10^-14 J of work to move charge 2 from 5 meters away to 4 meters away from charge 1.

To calculate the work required to move charge 2 (Q2) towards charge 1 (Q1), we can use the formula for electric potential energy:

Work = ΔPE = k * (Q1 * Q2) * (1/r_final - 1/r_initial)

where k is the electrostatic constant (8.99 × 10^9 N·m^2/C^2), Q1 and Q2 are the magnitudes of the charges, r_initial is the initial distance (5 meters) and r_final is the final distance (4 meters).

Plugging in the values, we have:

Work = (8.99 × 10^9) * (1.1 × 10^-5 C) * (10^-6 C) * (1/4 - 1/5)

Work = (8.99 × 10^9) * (1.1 × 10^-5 C) * (10^-6 C) * (0.2)

Work ≈ 1.979 × 10^-2 J

In the system of stream orders, the smallest unit in the network is at the 1st order.

Stream orders are a way of classifying streams and rivers based on their position within a drainage network. The smallest unit in the network, also known as headwater streams, are classified as 1st order streams. These are the smallest tributaries that have no other streams flowing into them. As streams merge, the order increases. When two 1st order streams join, they form a 2nd order stream. When two 2nd order streams join, they form a 3rd order stream, and so on. However, if a lower-order stream joins a higher-order stream, the order of the higher stream remains the same. For example, if a 1st order stream joins a 3rd order stream, the resulting stream remains a 3rd order stream. This classification system helps scientists, hydrologists, and environmental managers better understand and manage river systems and their ecological impacts.

Answer: C. Ocean waves can only bring energy to the shore; the particles of the medium (water) simply oscillate about their fixed position.

Explanation:

The reason why the beach is not completely submerged and the reason why the middle of the ocean has not been depleted of its water supply is due to the fact that water isn't transported by ocean waves.

It should be noted that even a single drop of water cannot be brought by the ocean wave to the shore from the middle of the ocean.

The only thing that the ocean waves can bring to the shore is energy. Hemce, the water particles oscillate in their fixed position which is vital in making sure that the beach isn't piled up with water.

Answer:

Q. 2 is plates move past each other sideways

Explanation:

Shocks cause shifts in AD and AS curves, and the placement of point E, representing the new equilibrium, depends on these shifts.

Shocks can affect the economy through changes in aggregate demand or aggregate supply. An increase in aggregate demand would shift the AD curve to the right, reflecting higher overall demand for goods and services. This shift would result in a higher level of output and prices in the short run. Consequently, point E would be placed at a higher level of output and higher price level.

On the other hand, a positive supply shock, such as a decrease in production costs or an increase in productivity, would shift the AS curve to the right. This shift implies higher output and lower prices in the short run. In this case, point E would be located at a higher level of output and a lower price level.

Conversely, a negative supply shock, such as an increase in production costs or a decrease in productivity, would shift the AS curve to the left. The resulting equilibrium at point E would be characterized by lower output and higher prices in the short run.

To determine the placement of point E, it is necessary to identify the specific shifts caused by the shocks, such as an AD shift, a positive supply shock (AS shift to the right), or a negative supply shock (AS shift to the left). Once the shifts are identified, the corresponding changes in output and price level can be determined, and point E can be placed accordingly in the new short-run equilibrium.
