Given: Work W = 3,500 J; Force f = 250 N; Weight w = 765 N
Required: Distance d = ?
Formula: Work = force x distance or W = f x d
Distance d = W/f
d = 3,500 J/250 N
d = 14 m
Answer:
Diameter will be 351.42 mm
Explanation:
We have given current flowing in the copper wire i = 310 A
Voltage drop across the wire V = 0.55 volt
We know that resistance is given by
Length of the copper wire l = 1 m
Resisitivity of the copper wire
We know that resistance
As area
So diameter = 351.42 mm
Answer:
To increase the volume of moving water, impoundments or dams are used to collect the water. An opening in the dam uses gravity to drop water down a pipe called a penstock. The moving water causes the turbine to spin, which causes magnets inside a generator to rotate and create electricity.
