Answer:
A. he can hear music coming from the radio.
Explanation:
Jeff knows that the radio produces sound energy because he can hear music coming from the radio.
The music from the radio is a form of sound energy.
- Sound energy is a form of energy dissipated from a body and can be discerned by humans.
- Sound is a mechanical wave that requires a material medium for its propagation.
- It travels by series of rarefaction and compression along its path of motion.
- Since sound energy is an energy in motion, it is a kinetic energy.
- It travels parallel to its source and therefore, it is a longitudinal wave.
Answer:
mass x velocity
Explanation:
The momentum of an object is the product of its mass and velocity;
Momentum = mass x velocity
Mass is the quantity of matter in a body
Velocity is the rate of change of displacement with time.
Also, momentum is used to quantify the particular amount of motion a body can give.
5 because there is 5 electrons. In order for an atom to be neutral it has to have the same amount of positive and negative charges.
The answer is B. 1,4, and 6
Answer:
Unit of work done is Joule. Therefore, the dimension formula of work is represented as [M1 L2 T-2].Explanation:
