Answer:
I'm not sure what your answer choices are but I would consider it a conductor.
Explanation: Things that conduct anything are conductors.
I hope that this will help, good luck.
The electrical force between two charges is given by
where
k is the Coulomb's constant
q1 and q2 are the two charges
r is the distance between the two charges
We see that the magnitude of the force is inversely proportional to the square of the distance. Therefore, if the distance is increased to 3 times the original distance:
the magnitude of the force will change as
So, the correct answer is <span>
it will decrease to one-ninth the original force.</span>

Answer:
4213.2 Km/h
Explanation:
Given:
Initial Speed of space vehicle relative to Earth, u = 4150 km/h
Mass of rocket motor = 4m
speed of the rocket motor relative to command module , v' = 79 Km/h
Mass of the command module = m
Now,
let the speed of command module relative to earth be 'v'
From the conservation of momentum, we have
( 4m + m ) × u = m × v + (4m × (v - v'))
or
5m × 4150 = mv + 4mv - 4mv'
or
20750 = 5v - ( 4 × 79 )
or
20750 = 5v - 316
or
v = 4213.2 Km/h
