Answer:
C
Explanation:
Formula E=F/C also E=V/d
In this case use the second formula; E=V/d
Data given; E=4N/C d=8m
So v=E X d
V=4x8=32V
k.e=eV= 2X32=64eV
The reactants are on the left and the products are on the right of the equation
Answer:
a) The brake force = -535.7N
b) acceleration = - 1.2m/s^2
Explanation: Please find the attached files for the solution.
Answer:
The length of the object would shrink to zero which is not possible.
Explanation:
A rocket or any body cannot reach the speed of light because according to theory of relativity the and the Lorentz factor the length of the object would shrink to zero and the time dilation for that body would be infinite.
The Lorentz factor is given as:

where:
v = speed of the moving object
c = speed of light
