b) Speed of a moving body is always higher than its velocity.
c) Speed of a moving body is its velocity in a given direction.
d) Velocity of a moving body is its speed in a given direction,​

Answer 1

Answer:

I hope that the correct answer is d)

Answer 2

Which of the following statement is correct regarding velocity and speed of a moving body?

Velocity of a moving body is its speed in a given direction is correct regarding velocity and speed of a moving body.

Explanation:

• We know that velocity is the speed with direction and magnitude as it is a vector quantity.

• Vector quantity is that quantity which have both direction and magnitude.

• We also know that speed haven't direction it just have magnitude as it is a scalar quantity.

• Scalar quantity is that quantity which have only magnitude.
