Answer:
The inventor of the electric cell was:
Alessandro Volta (in other words, Volta)
Explanation:
Unlike charges attracting each other
The potential energy of any object depends on its mass as well as its height off the ground.
Potential energy = mass x gravity x height.
We don't have enough information to compare the potential energies of these two objects because we don't know their masses.
Answer:
Rotational kinetic energy = 0.099 J
Translational kinetic energy = 200 J
The moment of inertia of a solid sphere is
.
Explanation:
Rotational kinetic energy is given by

where <em>I</em> is the moment of inertia and <em>ω</em> is the angular speed.
For a solid sphere,

where <em>m</em> is its mass and <em>r</em> is its radius.
From the question,
<em>ω</em> = 49 rad/s
<em>m</em> = 0.15 kg
<em>r</em> = 3.7 cm = 0.037 m


Translational kinetic energy is given by

where <em>v</em> is the linear speed.
