Explanation

• Stars generate their own light through nuclear fusion in their cores.
• It making them self-luminous.

Explanation

Plastic pipes and fixtures are manufactured using moulding techniques such as injection moulding or extrusion moulding.

This process shapes melted plastic into desired forms.

Explanation

The principle of conservation of linear momentum is a direct consequence of Newton's Third Law of Motion.

While Newton's Second Law relates force to the rate of change of momentum (F = dp/dt),

It's the reciprocal action-reaction nature described in the Third Law that leads to the preservation of total momentum in an isolated system. 

Explanation

Momentum is given by the formula: p = mv, where m is mass and v is velocity (or speed).

It depends on mass and speed, not on acceleration, so momentum is independent of acceleration.

Explanation

The correct answer is approximately 1479 J.

Explanation

The dead time of a GM counter is the brief period (about 10⁻⁴ seconds) after detecting a particle during which it can't detect another.

This happens because the detector needs time to reset.

It limits how fast the counter can measure radiation.

Explanation

A proton is made of two up quarks and one down quark (uud).

This combination gives the proton its positive charge (+1).

Explanation

The quantity that indicates the state and direction of a vibrating body is phase. 

Explanation

 The temperature coefficient of resistance indicates how the resistance of a material changes with temperature.

In semiconductors, as temperature increases, more charge carriers (electrons and holes) become available, so resistance decreases.

Therefore, the temperature coefficient is negative.

Explanation

Weather satellites are used to provide weather forecasting and monitoring of weather patterns, climate change.
