Pls mark me brainliest
Explanation:
The wheel and axle is a simple machine consisting of a wheel attached to a smaller axle so that these two parts rotate together in which a force is transferred from one to the other.
I’m just gonna try an wander the the best I can, sorry if this is wrong I haven’t been taught this subject yet-
I’m Guessing its sublimating
( I’m sorry if this is wrong, remember I haven’t been taught this yet I’m only in 6th-)
Answer:
V' = V/2
Explanation:
The voltage across a parallel plate capacitor is given as follows:
V = Q/C
where,
V = Voltage across capacitor
Q = Charge on Capacitor
C = Capacitance of Capacitor = A∈₀/d
Therefore,
V = Qd/A∈₀
where,
A = Area of plate
d = distance between plates
∈₀ = permittivity of free space
FOR CAPACITOR 1:
Q = Q
d = d
A = A
V = V
Therefore,
V = Qd/A∈₀ --------------- equation (1)
FOR CAPACITOR 2:
V' = ?
Q' = Q
d' = d
A' = 2A
Therefore,
V' = Q'd'/A'∈₀
V' = Qd/2A∈₀
V' = (1/2)(Qd/A∈₀)
using equation (1):
<u>V' = V/2</u>
The rest energy of the proton will be 938 MeV. The rest energy is related to the rest mass of the proton.
<h3>What is rest energy?</h3>
The rest energy is the rest mass times the square of the speed of light of a particle at rest in an inertial frame of reference.
The rest energy is found as;
Convert into the mega electron volt;
Hence, the rest energy of the proton will be 938 MeV
