The beam in a cathode ray tube is moved by an electric force. what did
scientists infer about atoms from this experimental result?
oa. electrons have more energy the farther they are from the nucleus.
ob. atoms are made up of smaller particles.
oc. atoms are small particles that cannot be destroyed or divided.
od. atoms have a dense, positively charged center.

At the negative terminal of the battery the electron has electric potential energy. what happens to this energy as the electron jumps from the negative to the positive terminal?

What’s the kinetic energy of the object? use . erica is competing in the shot put event at a track meet. she hurls a shot with a mass of 4 kilograms at a speed of 9 meters/second. the shot’s kinetic energy is joules.

Consider three resistors with unequal resistances connected in parallel to a battery. which of the following statements are true? check all that apply: the current flowing through each of the resistors is the same and is equal to the current supplied by the battery. the voltage across each of the resistors is the same and is equal in magnitude to the voltage of the battery. the algebraic sum of the currents flowing through each of the three resistors is equal to the current supplied by the battery. the algebraic sum of the voltages across the three resistors is equal to the voltage supplied by the battery. the equivalent resistance of the combination of resistors is greater than the resistance of any one of the three resistors. the equivalent resistance of the combination of resistors is less than the resistance of any one of the three resistors.
