Another term for equilibrium price is a. dynamic price. b. market-clearing price. c. quantity-defining price. d. balance price.
victus00 [196]

Answer:

Option B is correct.

Another name for equilibrium price is **market-clearing price**

Explanation:

Equilibrium price is defined as the price at which the quantity of products/goods/services demanded is equal to/matches the quantity of products/goods/services supplied.

The equilibrium price is also called the market clearing price because, at this price, there is no supply leftover (surplus) or demand leftover (deficit). The market is literally cleared!

How does gravity keep the planets in orbit around the sun
mrs_skeptik [129]
Hi there!

Gravity from the sun is even and makes a planet orbit the sun by exerting a force that pulls the planet towards it. Since the gravity of the sun is always the same (or very, very similar), the planet's orbit stays the same.

Hope this helps!

If a system performs 147 kJ of work while receiving 47 kJ of heat, what is change in its internal energy?
Verdich [7]

Answer:

-100 kJ

Explanation:

We can solve this problem by applying the first law of thermodynamics, which states that:

\Delta U = Q-W

where:

\Delta U is the change in internal energy of a system

Q is the heat absorbed/released by the system (it is positive if absorbed by the system, negative if released by the system)

W is the work done by the system (it is positive if done by the system, negative if done on the system)

For the system in this problem we have:

W = +147 kJ is the work done by the system

Q = +47 kJ is the heat absorbed by the system

So , its change in internal energy is:

\Delta U = +47 - (+147) =-100 kJ
