Answer:
because it’s suppose to be red like a stop light.
Explanation:
So it tells you to stop
Since, F = k . ∆x
Therefore, k = F / ∆x = 250 / 0.2 = 1250 N/m
(ps: convert 20 cm into 0.2 m)
Answer:
W = F * S = Newtons * Distance = Joules (definition)
Joules and KiloJoules are obviously methods of describing energy
F = M a = kg * m / s^2 definition of force
F * S = kg * m^2 / s^2 also describes work
Answer:
The pressure in the water is 
Explanation:
Given that,
Depth = 101 m
Let P be the pressure at the bottom of water at a depth
We need to calculate the pressure in water
Using formula of pressure

Where,
= atmospheric pressure
= pressure in water
Put the value of
in to the formula

Put the value into the formula


Hence, The pressure in the water is
