Explanation

Shock absorbers in cars are designed to reduce the amplitude of vibrations (oscillations) after hitting a bump.

This is done by dissipating energy (usually through hydraulic or pneumatic damping).

The motion gradually dies out over time, which is characteristic of a damped oscillation.

Explanation

In a spinning dryer, the clothes are forced to move in a circle by the centripetal force provided by the drum.

However, the water in the clothes lacks this centripetal force (no direct contact with the drum),

So it moves in a straight line (due to inertia) and is flung outward through the holes in the drum.

Explanation

The SI unit for flow rate is cubic meters per second (m³/s)

Explanation

Aerosol cans are typically made of metal (aluminum or steel).

It often contain recycled content, usually over 25%.

These containers are recyclable.

Explanation

Total internal reflection occurs when light travels from a denser to a rarer medium, and the angle of incidence exceeds the critical angle.

At this point, light is completely reflected back into the denser medium.

Explanation

1 kilocalorie (kcal) = 4184 joules, commonly used in food energy.

1 calorie (cal) = 4.184 joules, so 1000 cal = 4184 J.

Explanation

Electrons are elementary particles, meaning they are not composed of smaller components.

Hence, they are considered one of the most refined and fundamental forms of matter.

Explanation

The maximum kinetic energy (K.E.) of photoelectrons depends on the frequency of the incident light, not its intensity. 

According to Einstein's photoelectric equation:

K.E. = hf - φ

where hf is the energy of the photon, which depends on its frequency (f).

Explanation

The Carnot cycle is best represented on a Pressure-Volume (P-V) graph.

It consists of two isothermal and two adiabatic processes, clearly shown in the P-V diagram.

Explanation

In an ideal gas, it is assumed that there are no intermolecular forces between molecules.

Hence, the potential energy associated with the molecules is considered zero.
