Answer:
BOTH the size of the force AND the mass of the object
Explanation:
Acceleration of an object is the rate of change of its velocity.
The relation between force, mass and acceleration is given by the formula as follows :
F = ma
m is mass
a is acceleration
It would mean that the change in motion or the acceleration of an object depends on both the size of the force and the mass of the object. Hence, the correct option is (c).
The answer is D) the object must move. The definition of work is movement (in any form).
Hope this helped! If it did, would you mind marking my answer as Brainliest? Thanks :D
P = 10^5 - ρ (average)gh
where ρ (average) = average air density between 0 and 5000 m = (1.22+0.74)/2 = 0.98
we know g & h
I get P = 52470 Pa
