Which illustrates the first law of thermodynamics?

Explain the concept of "charge" and how it relates to electricity?

The use of gravity waves, which do not interact with matter in the way electromagnetic waves do, hopefully will enable astronomers to study the actual formation of black holes and neutron stars. A.

We define the electric field as the force per charge. The units for this definition are newtons per coulomb. When we worked through the unit on electric potential, we related the field to the potential through the equation E = - ΔV / d.

What should a free-body diagram look like for a skydiver that is still speeding up as he falls? There is an arrow up for air resistance and an arrow down for gravity. The arrows are the same length.

As a rocket moves farther and farther upward from the launch pad, what happens to the strength of Earth's gravitational field around the rocket? a. It gets weaker. b. It grows stronger. c. It remains constant.

Sully uses a battery and a coil of wire to create an electromagnet. Using the same materials, if he wants to increase the strength of his electromagnet, he must the number of loops in the coil of wire along its length.
