Explanation

Electric current is defined as the rate of flow of charge through a conductor.

Its formula is 𝐼 = 𝑄/𝑡, where 𝐼 is current, 𝑄 is charge, and 𝑡 is time.

Explanation

The area under a force–displacement graph gives the work done by the force.

This is because Work = Force × Displacement, graphically represented by the area.

Explanation

Natural disasters such as earthquakes, volcanic eruptions, and floods can alter the Earth's surface, changing the shape of the land.

These events can lead to the formation of new landforms or the destruction of existing ones.

Which are also commonly referred to as "Calories". 

Explanation

A body is in equilibrium when the net force acting on it is zero, and it is not changing its motion.

This means that the body is either at rest or moving with a constant velocity (uniform speed), but not accelerating.

Explanation

The prefix deka (da) means 10¹ or 10.

It's used in the metric system (e.g., 1 dekameter = 10 meters).

Explanation

Derived quantities are formed from base quantities through mathematical operations.

m² (square meter) is derived from the base unit meter (m) and represents area.
