Question

Which of the following is a vector quantity?

A) The power of a battery.

B) The density of an apple.

C) The volume of a mountain.

D) The weight of an elephant. ​

Answer 1

which of the following is a vector quantity?

• D) The weight of an elephant

Weight is the only quantity that is vector among the others. Power, density, volume all are scalar quantities.

• Power:- It is a scalar quantity. It doesn't need a direction to specify it.
• The reason for others to be a scalar quantity is also same!

Weight is a scalar quantity because it has a direction. Weight is the force applied by earth on an object. Now, the force must have a direction so it is a vector quantity!!~

Answer 2

D) The weight of an elephant

Step-by-step explanation:

Weight, acceleration, and velocity are all considered vector quantities because gravitational forces of the Earth are required to push them in certain directions. Always remember:

`\displaystyle Vector \hookrightarrow Speed\:AND\:Direction \\ Scalar \hookrightarrow Speed`
