Which of the following describes density only in terms of metric units? a. kilograms per cubic meter b. pounds per square meter c. pounds per cubic foot d. grams per cubic foot

How does heat flow? A. Heat flows from all objects to all other objects. B. Heat flows from a warmer object to a colder object. C. Heat does not actually flow from one object to another.

To increase the amount of current flowing in a circuit, how should you change the voltage if the resistance stays the same?

Cart 1 has an initial velocity and hits Cart 2 which is stationary. After a perfectly inelastic collision, the combined carts are traveling with exactly one third the initial velocity of Cart 1, and in the same direction.

Total energy input is 1400 and my efficiency is 80% so what is the useful energy output in jules?

What is the force of gravity acting on a 2000-kg spacecraft when it orbits two Earth radii from the Earth's center (that is a distance r=6380 km above the Earth's Surface. The mass of the Earth is 5.98 x 1024 kg.

An LC circuit has a 6.00 mH inductor. The current has its maximum value of 0.570 A at t = 0s. A short time later the capacitor reaches its maximum potential difference of 66.0 V. What is the value of the capacitance?

The first law of thermodynamics states that ΔE = Q - W. Is this also a statement of the principle of conservation of energy? Yes, the heat added and the change in internal energy of the gas equal the work done by the piston.

How can we calculate the density of a sustance that has irregular volume
