Answer:
Eh = 21 [J]
Removed as heat.
Explanation:
This is a case of energy conservation, we have to take into account the energies that go in and out of the system. In this case, 135 [J] of energy are entered in the form of work of the compressor to the chamber where the refrigerant is compressed, now of these 135 [J] 114 [J] were used as internal energy, this internal energy is used to increase the pressure and temperature of the refrigerant.
In this way the rest of the energy of the 135 [J] was lost in the form of heat to determine this loss of energy, we simply perform the arithmetic subtraction.
Eh = 135 - 114 = 21 [J]
Eh = 21 [J]
Answer:
i think since our body is relaxed and our minds are relaxing. i'm not completely sure but i just think that we are kinda partially unconscious in a sense, but i don't really know. i'm not a professional or anything so i guess i don't have a lot of experience in these types of things lol.

Answer:
option (B)
Explanation:
mass of proton, m = m
charge of proton, q = e
Time period, T = T
Initially the speed of proton is v.
The time period of the proton when it is moving in magnetic field perpendicular to the direction of magnetic field is given by
Where, r be the radius of circular path.
The relation between r and the speed v is given by
Where, B be the strength of magnetic field. Substitute this value of r in the expression of time period
Here, we observe that the expression for the time period is independent to v and r so, as we change the velocity, the time period remains same.
You can find velocity when acceleration is constant.
file example see below.
Explanation:
So basically yh first off the number for protons and electrons are the same and to find them is to look at the atomic number because the atomic number is the same as protons and electrons.
To find the neutrons you need to take the actual atomic number from the atomic mass unit.
Hope that helps yh don't stress it.
