Answer:
.
Explanation:
The mechanical energy of the system will be the kinetic energy plus the elastic potential energy:
.
We know that the equation for the kinetic energy is
, where <em>m </em>is the mass of the object and <em>v </em>its velocity.
We know that the equation for the elastic potential energy is
, where <em>k</em> is the spring constant and
the compression (or elongation) respect to equilibrium.
So for our values we have:
.

here are five harmful effects of friction
1) It makes us use more fuel
2) The gears in your care will wear down if not lubricated with oil
3) The friction up the device so, due to heating machine can damaged
4) Causes the production of heat between surfaces when the object move
eg : car brakes and tyres heat up due friction
5) Even our shoes wear out due to friction with the ground ; Friction with air causes air craft , meteors to heat

a steep-sided valley formed by the downward displacement of a block of the earth's surface between nearly parallel faults or fault systems.
You can do it I believe in you
Explanation:
(a) We have,
Length of solenoid, l = 55 cm = 0.55 m
Diameter of the solenoid, d = 10 cm
Radius, r = 5 cm = 0.05 m
Number of loops in the solenoid is 1000.
(a) The self inductance in the solenoid is given by :

A is area

(b) The energy stored in the inductor is given by :

Hence, this is the required solution.
