Assume you have a person with a mass of 65 kg riding a skateboard down a ramp. While they are still 4.8 m high, they are traveling at a speed of 8.0 m/s.
a) Calculate the Eg. [write here]
b) Calculate the Ek [write here)
C) Calculate the Etotal. [write here]
If the ramp had a total height of 8.0 m, what would be their Eg, Ek, and Etotal at that height?
[write here]

adding a(n) to an electric circuit would increase the magnetic field around a wire;

b. solenoid

a solenoid is a type of electromagnet whose purpose is to generate a controlled magnetic field.

if the purpose of the solenoid is instead to impede changes in the electric current, a solenoid can be more specifically classified as an inductor rather than an electromagnet.

3. dark matter

empty space could also be a simple vacuum
