Question 1

Volt

Answer 1

1J per coulomb

Question 2

Couple

Answer 2

Pair of equal and opposite coplanar forces

Question 3

Waves
Intensity and Aplitude

Answer 3

Intensity is prop to A ^2

Question 4

State what js meant by Root mean squared voltage

Answer 4

the square root of the mean of the squares of all the values of voltage in 1 cycle

Question 5

Escape velocity proof

Answer 5

1/2mv^2 = GMm/r

v^2 = 2Gm/r

v = root(2V)

So velocity required = root of (2x electric potential)
