Answer: option b, the distance the spring stretches.

Hook's law is: F = - K Δx

Where:

F stands for the force that the spring exerts

K is stands for the constant of the spring

Δx stands for the distance the spring is displaced from the equilibrium point.

And the negative sign is due to F is opposite to the direction in which the spring is away from the equilibrium point.

A hydraulic press has a safety feature which consists of a hydraulic cylinder with a piston at one end and a safety valve at the
Sergio039 [100]

Answer:

Explanation:

radius of cylinder r₁ = .02 m

radius of safety valve r₂ = .0075 m

force exerted by spring on safety valve = 950 x .0085 = 8.075 N .

Force required on piston of cylinder = F

Applying Pascal's law

8.075 / 3.14 x .0075²  =  F / 3.14 x .02²

F = 8.075 x .02² / .0075²

= 8.075 x 7.111

= 57.42 N .

Since the biker is moving at constant speed

so we will have

v = \frac{distance}{time}

here we know that

distance = 2\pi R

time = 4 second

now we have

v = \frac{2\pi R}{4} = \frac{\pi R}{2}

now at the top point it feels free fall

so it is

mg = \frac{mv^2}{R}

v^2 = Rg

(\frac{\pi R}{2})^2 = Rg

R = \frac{4g}{\pi^2}

so height of the bike at the top is same as diameter

h = 2R

h = \frac{8g}{\pi^2} = 7.95 meter

Yes it will hurt on falling from this height
