Answer:
Diameter of wire B is 2 times the diameter of wire A
Explanation:
We have given two wire A and B
They are made up of same material and length of both the wire is sane
So 
Let the resistivity of both the wire is 
It is given that wire A has 4 times the resistance as wire B
So 
So 
( As )
So diameter of wire B is 2 times the diameter of wire A

Answer:
Period
Explanation:
we know that
The period of a wave is the time required for one complete cycle of the wave to pass by a point.
Answer: 1339.5 joules
Explanation:
Gravitational potential energy, GPE is the energy possessed by the jumper as he moves against gravity.
Thus, GPE = Mass m x Acceleration due to gravity g x Height h
Since Mass = 67kg
g = 9.8m/s^2
h = 2.04 metres
Thus, GPE = 67kg x 9.8m/s^2 x 2.04m
GPE = 1339.5 joules
Thus, the gravitational potential energy at the highest point is 1339.5 joules
