What is the acceleration of a 25 kg mass pushed by a 10n force
2 answers:
Answer:
The answer is acceleration is equal to 0.4m/s^2
Step by Step Explanation:
1) Acceleration is a vector derived magnitude that indicates the variation of speed per unit of time.
2) Taking into account Newton's Second Law, which determines a proportional relationship between force and variation in the amount of movement or linear momentum of a body. That is, the force is directly proportional to the mass and acceleration of a body.
3) This law is expressed by the formula F = m.a where (F) represents Force (m) represents mass and (a) represents acceleration.
4) Knowing this we can issolate (a) from the formula and we would have:
5) Having this we can now replaces the values given in the problem.

Answer:
the ratio of the bubble’s volume at the top to its volume at the bottom is 1.019
Explanation:
given information
h = 0.2 m
= 1.01 x
Pa
=
+ ρgh, ρ = 1000 kg/
= 1.01 x
Pa + (1000 x 9.8 x 0.2) = 1,0296 x
Pa
=
=
Pa
thus,
