The answer is C!! 100 kilometers per hour is an average speed.
Reserves might last 53.3 years.
Earth’s mineral resources:
Answer:
Yes
Explanation:
Energy can be transferred from one object to another or between energy stores within the same object. For example on a pool table when white ball hits another ball energy is transferred from the kinetic store of the white ball to the kinetic store of the other ball.
Answer:
Energy stored, U = 66.6 J
Explanation:
It is given that,
Number of turns in the solenoid, n = 500
Radius of solenoid, r = 1.5 cm = 0.015 m
Distance, d = 15 cm = 0.15 m
Let U is the energy stored in the solenoid. Its formula is given by :

L is the self inductance of the solenoid

N is the no of turns per unit length


L = 0.00148 Henry

U = 66.6 J
Out of given options, the correct option for the energy stored in the solenoid is 70 J. So, the correct option is (a) "70 J".
