The foot pedal on hydraulic brake system exerts a force of 45 lb on a piston with a diameter of 1.00 cm. The brake fluid in the

ElenaW [278]

Answer:

the correct answer is C, 281 lb

Explanation:

This is an exercise in fluid mechanics specifically on Pascal's principle, which states that the pressure in a fluid is equal to all points that are at the same depth

P = $\frac{F_{1} }{A_{1} }$ = $\frac{F_{2} }{A_{2} }$

If we use the subscript 1 for the piston diameter mentor (d = 1.00vm) which is r = 0.05 cm, the force is F1 = 45 lb

F₂ = \frac{F_{1} }{A_{1} } F₁

in area of a circules

A = π r²

we substitute

F₂ = $\frac{r_{2}^2 }{r_{1}^2} F_{1}$

let's calculate

F2 = 2.50² / 1.00² 45

F2 =281 lb

therefore the correct answer is C

I need help in this small question:

Natali5045456 [20]

Answer:

1) The energy released during nuclear fission or fusion, especially when used to generate electricity is called nuclear energy.

2) It is not renewable because it is an element that has no way whatsoever to regenerate or replicate itself, nor gets created by any natural terrestrial means, neither makes itself available by arriving from outer space (like sunlight). There is a limited amount of it available on the Earth, and every bit you use is a bit you’ll never have available again (as Uranium atoms get destroyed by the fission process).

Hope this helps You
