Answer:
Capillary Action.
Explanation:
Capillary action is the ability of a liquid to flow in narrow spaces without the assistance of, or even in opposition to, external forces like gravity.
answer:
2.5 m/s²
Explanation:
120 km/h = 120 ÷ 3.6 = 100/3 ≈ 33 m/s
a = (v2 - v1)/∆t = (33m/s - 0)/ 13s = 33/13 m/s²≈ 2.5 m/s²
Answer:
Tension.
Explanation:
The tighter a string is, the more tension is applied to it; the more loose a string is, less tension is applied to it.
Therefore, when you adjust the tightness of a string you are tackling with it's tension.

Answer:
amount of work done = -1.77 J
Explanation:
given data
mass = 0.25 kg
speed = 5 m/s
height = 2m
to find out
amount of work done by the water on the ball bearing
solution
we get here potential energy when ball fall
potential energy = mgh
potential energy = 0.25 × 9.8 × 2
potential energy = 4.9 J
and that lose potential energy gain by kinetic energy that is express as
kinetic energy = 0.5 × m × v²
kinetic energy = 0.5 × 0.25 × 5²
kinetic energy = 3.13 J
so we get now work done that is
work done = kinetic energy - potential energy
work done = 3.13 J - 4.9 J
amount of work done = -1.77 J
Yes. Newton's laws do not apply at the subatomic level. There you are entering the weird world of Quantum Theory. Go read about the '2 holes experiment'. It will blow your mind.
