Explanation

Hadrons are particles that participate in strong nuclear force and include protons, neutrons, and heavier particles.

They are generally equal to or heavier than protons in mass.

Explanation

Inertia is the natural tendency of an object to remain at rest or in motion with constant velocity.

Explanation

The retina is the innermost layer of the eye that senses light and sends visual signals to the brain, much like the film in a camera captures images.

Explanation

The repulsive energy between particles is always positive.

Explanation

The general formula for rotational kinetic energy is:

K.E.=1​/2Iω^2

Where:

• $I$= moment of inertia

• $omega$ = angular velocity

For a hoop (thin ring) of mass
$m$ and radius r:

$I=mr^2$

So, plugging into the formula:

K.E.=1/2⋅mr^2 ⋅ω^2= 1/2​Iω2

the work done by the patient's weight while being pushed in the wheelchair is no work.

Explanation

• The Second is a fundamental unit of time in the International System of Units (SI).
• It is one of the seven base units that are used to derive all other units.

Explanation

• Transparent objects do not form shadows because they allow all light to pass through them.
• So there is no blocking of light to create a shadow.

Explanation

The type of gas utilized in refrigerators to chill water is Tetrafluoroethane, also known as R-134a or HFC-134a.
