D. The string vibrated because of resonance, which happened because the tuning fork and guitar string have same natural frequency.
Answer:
1: is A
2: is C
Explanation:
1: because all other option would imply that the truck was not moved from from its previous position due to the lack of work / force exerted by the car
2: this is because the less dense ball will have less opposing force action on it causing it to move / accelerate / go at a faster speed
The continuious physical force per unit area that one region of a gas, liquid, or solid exerts on another.
The answer is constant acceleration.
Answer:
A. Kinetic energy is converted to electric potential energy, and the proton moves more slowly.
Explanation:
When a moving proton is brought close to a stationary one, the kinetic energy of the moving one is converted to electric potential and the proton moves more slowly.
Kinetic energy is the energy due to the motion of a body. A moving proton will possess this form of energy.
Two protons according to coulombs law will repel each other with an electrostatic force because they both have similar charges. This will increase their electric potential energy of both of them.
Potential energy is the energy at rest of a body. As it increases, the motion of a body will be slower and it will tend towards being stationary.
