Explanation
Energy = force × distance, so if both are increased by 4 times then energy will increase by 16 times.
1 yard = 36 inch = 36 × 2.54 cm = 0.9144 m.
1 newton = 105 dyne
Since for 50.14 cm, significant number = 4 and for 0.00025, significant number = 2
Quantity C has maximum power. So, it brings maximum error in P.
Percentage error in X = aα + bβ + cγ
