Answer: When an earthquake occurs energy is transferred, from where the rocks break, and travels throughout the world. The bigger the quake the further from the epicentre the waves will travel. There are four types of earthquake wave generated during an earth quake

the stone projected straight up
Answer:
ΔV = 1139.3 V = 1.139 KV (+ve sign shows V goes up)
Explanation:
The potential difference while moving from point A to Point B is given as follows:

where,
ΔV = potential difference from A to B = ?
= Potential at point A = 
= Potential at point B = 
Therefore,

where,
k = Colomb's Constant = 9 x 10⁹ N.m²/C²
q = magnitude of charge = 4.88 x 10⁻⁸ C
= distance of point A from charge = 1.36 m
= distance of point B from charge = 0.538 m
Therefore,

<u>ΔV = 1139.3 V = 1.139 KV (+ve sign shows V goes up)</u>
