Answer:
Choice b is correct answer.
Explanation:
We have given the mass of a cat.
mass = m = 4.6kg
We have to find the weight of cat on earth' surface.
The formula to find weight is:
weight = mass × gravity
w = mg
The value of gravity on earth surface is 9.8 m/sec².
Putting values in above formula, we have
w = 4.6 × 9.8 (kgm/sec²) ∴ kgm/sec² = Newtons
w = 45 Newtons which is the answer.
