Explanation

KE = 1/2mv²

Given m = 0.03 kg, v = 400 m/s

KE = 1/2 × 0.03 × 400 × 400

= 1/2 × 0.03 × 160000

= 1/2 × 4800

= 2400 J

Explanation

A diverging beam consists of rays spreading out from a point or axis.

It occurs when light passes through a concave lens or reflects from a convex mirror.

Explanation

A star with an initial mass more than five times that of the Sun ends its life as a black hole after a supernova explosion.

Its gravitational pull becomes so strong that not even light can escape.

Explanation

An electrostatic precipitator is a device used in factories and power plants to remove dust and smoke particles from exhaust gases.

It helps in air pollution control by using electrical charges to attract and collect harmful particles.

Explanation

The hypocenter is the point inside the Earth where the rocks break, causing an earthquake.

The point directly above the hypocenter on the surface is called the epicenter.

Explanation

The International Space Station (ISS) orbits Earth at an average altitude of around 400 kilometers.

This low Earth orbit allows it to circle the Earth roughly every 90 minutes.

Explanation

Sand particles are generally grey in color, though they can vary depending on their mineral content.

They are light in weight and have larger, coarse grains compared to silt or clay.

Explanation

The substance reduces to (1/16) = (1/2)^4 of its original mass.  

This means 4 half-lives = 40 days  

So, 1 half-life = 40 / 4 = 10 days  

Explanation

Let’s assume two cases:

• If $f = 3$ (monatomic gas), then:

  γ=3+2​/3=5/3​

• If $f = 5$ (diatomic gas), then:

  γ=5+2​/5=7/5​

Since the question asks for γ when degrees of freedom are 3 and 5, and γ = Cp/Cv, then:

• For f = 3 → γ = 5/3

Explanation

 The equation used for evaluating time in quantum fields is the Schrodinger equation.
