Explanation

 A calorie is a unit of energy, specifically used to measure heat energy.

1 calorie is the amount of heat required to raise the temperature of 1 gram of water by 1°C.

In dietary terms, we use kilocalories (kcal) — where 1 kcal = 1000 calories — but it still measures energy, not diet or food itself

Explanation

The correct choice is "is watching" because it follows the present continuous tense, which is used to describe actions happening right now.

Explanation

 Those substances through which electric current cannot pass are called insulators.

Insulators have very high electrical resistance

. For example, wood, rubber, glass, paper, plastic and wax are insulators of electricity.

Insulators cannot conduct electricity due to absence of free electrons in them.

Explanation

When two bodies are moving in opposite directions, their velocities are added to find the relative velocity.

Let's say the velocities of the two bodies are v1 and v2.

Relative velocity = v1 + v2

Since both velocities are non-zero and in opposite directions, the relative velocity will be greater than the absolute velocity of either body.

So, the statement "Relative velocity > Absolute velocity" is true.
