F = m×a
60 N = 30 kg × a
30 × a = 60
a = 60/30
a = 2 m/s²

<em>The acceleration of an object depends directly upon the net force acting upon the object, and inversely upon the mass of the object. </em>
<em></em>
Explanation:
If the net force increases while the mass of the object remains the same, the amount of acceleration also increases.
However, when the mass of the object increases while the net force remains the same, the amount of acceleration decreases.

(89000/102000)×100
=87.25%
(92000/104000)×100
=88.46%
efficiency is (output/input)×100
if u get confused which way input and output should go, remember the smaller value is always output and it's above in the fraction, then only it's possible to get a efficiency lower than 100.
