Compare the sum of the kinetic and potential energies of the pendulum at position A to the sum at position C. (Ignore friction.)

Titanium is softer than gold yes or no

When a rock is held above the ground, we say it has some potential energy. When we let it go, it falls and we say the potential energy is converted to kinetic energy. Finally, the rock hits the ground (and stays there).

3. When driving a car, the chemical energy in gasoline is converted to heat (thermal energy) in the engine. Most of this thermal energy is then converted to mechanical energy, which makes the car move. What happens to the rest of the thermal energy?

A clay ball with a mass of 0.48kg has an initial speed of 4.08m/s it strikes a 3.04kg clay ball at rest and the two balls stick together and remain stationary. What is the decrease in kinetic energy of the 0.48kg ball

Determine the velocity of a beam of electrons that goes undeflected when moving perpendicular to an electric and magnetic field. The electric field and the magnetic field are also perpendicular to each other and have magnitudes 7.7 x 10^3 V/m and 7.

What is the electric potential of a 2.2 µC charge at a distance of 6.3 m from the charge? Recall that Coulomb's constant is k = 8.99 * 109 N • ___ V What is the electric potential at a distance of 99 m from the charge?___ V

what is a possible unit for the product VI, where V is the potential difference across a resistor and I is the current through the same resistor?

In old western movies, cowboys often would put their ear to a train track to listen for an oncoming train. What benefit would this method provide over listening for a train by listening for sound through the air? A) The sound would be louder.

What is meant by "reflecting" and "refracting" telescopes?
