(A) 1% (B) 1/2%
(C) 2% (D) None of the above.
Light year is a unit of
(A) Time
(B) Mass
(C) Distance (D) Luminosity

same as that of
)
iii)​

Answer 1

Answer:

(1) Option (C) Force

(2) Option (C) 2%

(3) Option (C) Distance

Explanation:

(1) The powers seem to be missing in the question

But in all probability, the answer seems to be Force because the dimension of force is $[MLT^{-2}$

(2) if the error in the measurement of sides of a rectangle is Δa and Δb then the error in the area will be Δa+Δb

Here Δa = Δb = 1%

Therefore the error in the area = 2%

(3) Light year is the unit of distance.

Hope this answer is helpful.

Answer 2

1 answer is force. AND PLEASE MARK ME best explanet
