Change boring verb and ordinary adjectives

physics
A boy drops a 0.10 kg stone down a 150 m well and listens for the echo. The air temperature is 20°C. How long after the stone is dropped will the boy hear the echo? The speed of sound through air at 20°C is v = 343 m/s.

Lost in Physics
The strength of an electric field at 5.0 cm from a point charge is 100.0 N/C. What is the magnitude of the source charge? Show work so I understand how to do it. E=kQ/r^2 solve for Q, you have r, E What do I do NOW? I am lost

Physics
Calculate the force between a +5 µC test point charge and this source charge at a distance of 2.00 cm. (µC = 1.0 × 10–6 C) force=kq1q2/r^2 Have the formula now what do I do?

Physics
A 5.0 µC point charge is moved within an electric field and has an electric potential energy change of 10.0 J. What is the electric potential difference before and after the charge was moved? Show work. (µC = 1.0 × 10–6 Vq=energy so delta V must be 10 vo...

Physics
If the test charge were moved closer to the source charge, would the change in its potential energy be positive, negative or zero? Explain.

If I knew how to do it with formula I would have done it.
