Answer:
True
Explanation:
It's a bit hard to explain, so you can watch a youdube video on it or something.
Explanation:
It is given that,
Force on piston, F₁ = 8800 N
Area, 
Area, 
Let F₂ is the force exerted on the second piston. Using Pascal's law as :
Pressure at piston 1 = Pressure at piston 2




So, the force exerted by a second piston is 35200 N. Hence, this is the required solution.
it would be a chain reaction and a wave
Answer:
Equation for SHM can be written
V = w A cos w t where w is the angular frequency and the velocity is a maximum at t = 0
V1 = w1 A cos w1 t
V2 = w2 A cos w2 t
V2 / V1 = w2 / w1 since cos X t = 1 if t = zero
V2 / V1 = 2 pi f2 / (2 pi f1) = f2 / f1 = T1 / T2
If the velocity is twice as large the period will be 1/2 long
Answer:
K = 960 J
Explanation:
Given that,
Mass of a child = 20 kg
Mass of a sled = 10 kg
Speed of child on sled = 8 m/s
We need to find the kinetic energy of the sled with the child.
The total mass of child and the sled = 20 kg + 10 kg
= 30 kg
The formula for the kinetic energy of an object is given by :

Hence, the kinetic energy of the sled with the child is 960 J.
