Answer:

A.C. Generator

Explanation:

The device designed to convert chemical energy into kinetic energy is an A.C generator.

The generator uses fuel to cause the mechanical motion of the pistons in the device.

Chemical energy is a form of energy found between the bonds of compounds and molecules.
When the bonds are broken, energy is released.
The heat energy produced drives pistons and cause mechanical motion of the body.
This is a form of kinetic energy which causes the motion of a body.

(a) $x = \frac{m_2L}{m_1+m_2}$

<u>Explanation:</u>

Given:

Moment of Inertia of m₁ about the axis, I₁ = m₁x²

Moment of Inertia of m₂ about the axis. I₂ = m₂ (L - x)²

Kinetic energy is rotational.

Total kinetic energy is $E = \frac{1}{2} I_1w_0^2 + \frac{1}{2}I_2w_0^2 = \frac{1}{2} w_0^2(m_1x^2 + m_2(L-x)^2)$

Work done is change in kinetic energy.

To minimize E, differentiate wrt x and equate to zero.

$m_1x - m_2(L-x) = 0\\\\x = \frac{m_2L}{m_1+m_2}$

Alternatively, work done is minimum when the axis passes through the center of mass.

Center of mass is at $\frac{m_2L}{m_1 + m_2}$
