Answer:
Explanation:
speed of alien spaceship = .1 c
We shall apply formula of relativistic mechanics to solve the problem
relative velocity =
Here v = v₁ = .1 c
relative velocity = .1c + .1 c / 1 - .1²
= .2 c / .99
= .202 c
The earth would receive the signal at the speed of .202 c .
Answer:
The speed of electron is and the speed of proton is 2468.02 m/s.
Explanation:
Given that,
Electric field, E = 560 N/C
To find,
The speed of each particle (electrons and proton) 46.0 ns after being released.
Solution,
For electron,
The electric force is given by :
Let v is the speed of electron. It can be calculated using first equation of motion as :
u = 0 (at rest)
For proton,
The electric force is given by :
Let v is the speed of electron. It can be calculated using first equation of motion as :
u = 0 (at rest)
So, the speed of electron is and the speed of proton is 2468.02 m/s. Therefore, this is the required solution.
