A generator transforms mechanical into electrical, a transformer reduces/increases the voltage of an alternating current, a magnet attracts metal, and a motor converts electrical energy into mechanical energy.
So, the answer is Motor.
Answer:
Explanation:
given that
Distance above the ground, s = 1.2 m
Time taken by the ball, t = 3 s
Velocity of the ball, v = 1.2/3 = 0.4 m/s
Maximum height reached by the ball is then given by the formula
H = v² / 2g
H = 0.4² / 2 * 9.8
H = 0.16 / 19.6
H = 0.0082 m or rather, 0.82 cm
Answer:
they are eletric and magnetic
Explanation:
<span>its kinetic energy is 7350kJ
</span>
Kinetic energy is given as =
Now, m = 12 gms = 0.012 kg
And, velocity = 35 kilometers/second = 35000 m/sec
Kinetic energy is given as =
![\frac{1}{2} 0.012 kg * 35000*35000 m/[tex] s^{2}](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7B2%7D%200.012%20kg%20%2A%2035000%2A35000%20m%2F%5Btex%5D%20s%5E%7B2%7D%20)

Answer:
A stone on the ground does not have zero energy…there is an internal potential in every object. Aldo is not in action or in any mechanical motion it is being acted upon by gravity and also molecular forces and energy.
