Question

Which of the following pairs do not match ?
(a) Rotational power - Joule/sec (b) Torque - Newton meter
(c) Angular displacement - radian (d) Angular acceleration - radian/sec​

Answer 1

Explanation:

angular acceleration - radian/sec.

radian/sec^2 is it correct.

And follow me

Answer 2

Answer:

Option (d) is incorrect.

Explanation:

(a) Rotational power: The work done per unit time is known as power or rotational power. Unit is Joule/sec.

Rotational power - Joule/sec (Pair matched)

Thus, option (a) is correct.

(b) Torque: The turning effect of a force about the axis of rotation is called torque. Unit is Newton meter or Nm.

Torque - Newton meter (Pair matched)

Thus, option (b) is correct.

(c) Angular displacement: The line that is rotated about the specified axis is called angular displacement. It is measured in radians.

Angular displacement - radian (Pair matched)

Thus, option (c) is correct.

(d) Angular acceleration: Rate of change of angular velocity with respect to time is called angular acceleration. Is is measured in radian/sec^2.

Angular acceleration - radian/sec (Pair mismatched)

Thus, option (d) is incorrect.
