Answer:Magnitude of potential energy before falling will be equal to the magnitude of the final kinetic energy, energy is only converted from potential to kinetic
Explanation: law of conservation of energy says that energy can neither be created or destroyed but Change from one form to another.so nothing will happen to the size of the potential energy when it changes to kinetic energy
Answer: 0.3872m
Explanation:
q= 100nC --> 100x10^-9 C
k= 9x10^9 Nm^2/C^2
E= 6kN/C --> 600 N/C

I think the answer is A (sorry if it isn't).
Answer:
physical change
Explanation:
its only changing things you see.
Answer:

Explanation:
One of the first propulsion characteristics given in the example is that all engines are equal.
In this way if we have 4 engines running at the same time, it means that its capacity is 100%.
Under this premise, if 100% is found, the Jet is capable of reaching a speed of 8.7m / s ^ 2.
However, the question is, what would happen if 2.4 "Engines" now work.
To do this then we make a simple equivalence,
If 4 engines is the equivalent of 100%, when would it be 2.4 engines?

In this way it would mean that the body could be driven to 60% of its total.
So
