True. Because you can touch it and it's physically real.
I believe your answer is d).

Answer:
The electric force between them is 878.9 N
Given:
Identical charge C
Separation between two charges m
For finding the electrical force,
According to the coulomb's law
Here, force between two balloons are repulsive because both charges are same.
Where N Therefore, the electric force between them is 878.
Explanation:
Answer:
5235.84 kg
Explanation:
There is one theorem - whose proof I will never remember without having to drag calculus in there - that says that the variation of momentum is equal to the force applied times the time the application last.
As long as the engine isn't ejecting mass - at this point it's a whole new can of worm - we know the force, we know the variation in speed, time to find the mass. But first, let's convert the variation of speed in meters per second. The ship gains 250 kmh,
