- At pole the gravitation is more than that of equator .
And according to newtons second law
Force=Mass×Acceleration
And
- Hence force varies directly with acceleration hence weight will be more .
Answer:
518400 Newton
Explanation:
Force F = mass m * Acceleration a
a = velocity v / time t
v = distance d / t
Therefore;
F = m * v² / d
with m = 2000 (unit not defined but say g)
v = 144 Km/h
d = 80 meters =0.08Km
F = 2Kg * 144Km/h * 144Km/h / 0.08Km
F = 518400 Newton
A calorimeter measures the amount of heat in a chemical reaction. So the answer would be C, specific heat.
