Their kinetic energies would be the same. The cart is empty and has a mass m. The second cart is of the same mass but loaded with twice the mass of the empty cart. 1 joule of work or energy is equal to the work done by a force of one newton acting through one meter.

<h3>What is kinetic energy? </h3>

A moving item or particle might have the power of a certain sort called kinetic energy. When work, which entails the transfer of energy, is done on an object by applying a net force, that object acquires kinetic energy. Kinetic energy, which depends on an item or particle's mass and velocity of motion, is a property of motion. Any combination of vibration, axis rotation, translation (or movement along a route from one place to another), and translation are all examples of motion.

The kinetic energy of each would be equal.

This is because the force, F, acting on them moves the same distance, d, hence the work done by the force is W = Fd.

Using the ideas of work-kinetic energy, let's now

W = K, where K is the difference in the kinetic energy of the carts.

Given that the effort done was the same for both carts, the change in kinetic energy would also be equal.

Since they start at rest, K = K' - K = K' - 0 = K'.

Therefore, the kinetic energies of the carts would be the same.

Answer:

Langerhan's cells

Explanation:

The Langerhan's cells arise from the bone marrow and migrate to the epidermis. The Langerhan's cells are the body's first line of defense and play a significant role in antigen presentation. They need special stains to be visualized and are primarily found in the stratum spinosum. These are the mesenchymal origin obtained from CD34 positive stem cells of bone marrow and are part of the mononuclear phagocytic system.

Determine whether the statement is true or false. Suppose P(t) represents the population of bacteria at time t and suppose P'(t)

Lorico [155]

Answer:

TRUE

Explanation:

If the population follows a logistic growth curve, the graph of P vs t will look like the diagram below.

The rate of growth (P') increases slowly at first, then increases rapidly from 2 to 4, and then slows down, but always P > 0.

The graph has an inflection point at (3, 1000). That's the point at which the rate of growth starts slowing down.

When t < 3, P'' > 0.

When t = 3, P'' = 0.
