<u>Answer:</u>
Temperature is always directly proportional to average kinetic energy of the material.
<u>Explanation:</u>
The average kinetic energy is given by the formula

Where K = average kinetic energy . R = gas constant , NA = avogadro's number, T = temperature
From the formula we can clearly see that K is directly proportional to T i.e kinetic energy increases with increase in temperature.
As a substance when it absorbs the heat , temperature increases which makes the faster movement of the particles thus increasing the kinetic energy.The above formula is applicable to gaseous molecules.
Momentum = mass • velocity
M = m • v
Speed is a scalar quantity
Velocity is a vector quantity
That is truly the only difference
The slope of an object is given relative to an origin.
Answer:
1. Wave period = 0.962 s
2. Will absorb red and blue and reflect green
Explanation:
1.
The wave period is:

Wavelength is the distance between crests. So replacing the given information:

2. In simple words the color of an object is the light it reflects. A green object reflects green light, and the rest is absorbed (red and blue).
Answer:
They have the same amount of energy
Explanation:
Electrons are said to be the subatomic particles that move around the nucleus of an atom. These electrons are negatively charged particles that are seen to be quite smaller than the nucleus of an atom.
The electron shells of these atoms are usually being filled from the inside out with the low-energy shells closer to the nucleus being filled before they can go into the much higher-energy shells that are a bit out
