False.
As temperature increases the more the electrons begin to vibrate more, as it decreases they vibrate less.
Answer: 0.169 (3 s.f.)
Explanation:
Force = 76 N
Spring constant = 450 N/m
Extension/displacement = x
Hooke's law states that: F = kx
Therefore, 76 = 450 X x
76/450 = x
0.169 (3 s.f.) = x
1. Stop transmitting start and stop sending photons. This is typical morse code like transmissions of information. By varying the pattern of starts stops you vary the information sent. Also used in digital communications over radios, modems, and pulse dialing over radio/phones.
<span>2. Change the frequency. You use a pattern of shorter and longer wavelengths of radio waves higher and lower energies of individual photons to transmit information. This is frequency modulation </span>
According to the Law of conservation of momentum, the total momentum of the system before and after the collision remains same. The momentum may transfer from one object to another as a result of the impact, but the overall momentum of the system remains same.
So, the correct answer is option a.
The total initial momentum of all objects interacting with one another usually equals the total final momentum.
The magnitude of the change in potential energy is equal to the kinetic energy,
or
Here, V is potential difference, q is charge, m is mass and v is velocity.
We can also write,
Given 
Substituting this value with mass of proton, 
and charge of proton,
we get
Therefore, the speed of proton is 
.
