Answer:

Step-by-step explanation:

Since the pipe is an enclosed container, we would apply Pascal's law which states that a pressure applied to a fluid in a closed container is transmitted equally to every point of the fluid and the walls of the container,

This means that pressure at input = pressure at output

Pressure = force /area

Input force = unknown

Input area = 0.1 m²

Output force = 9000N

Output area = 4m²

Therefore

Input force/0.1 = 9000/4

Input force = 0.1 × 9000 /4 = 225N

Answer:

The input force needed is 225 Newtons

Step-by-step explanation:

From hydraulic pressure laws,  we have that the pressure at the same level throughout the body of a fluid is equal.  

This means that for the Hydraulic Jack, input pressure = output pressure

Recall,Pressure is a ratio of force and area

i.e pressure = Force / Area

For the hydraulic jack to work properly, the pressure at the input end must be equal to the pressure at the output end.

\frac{F_{1}}{A{1}} = \frac{F_{2}}{A_{2}}

\frac{9000}{4}=\frac{Force}{0.1}

From this we can compute that the Input force = 225 Newtons

At the school the ratio of boys to girls is 5:3 if there are 385 boys in the school, how many students are there altogether?
ser-zykov [4K]

Answer:

There are 616 total students

Step-by-step explanation:

boys : girls: total

5           3      5+3 = 8

There are 385 boys

385/5 = 77

Multiply each term by 77

boys : girls: total

5*77  3*77   8*77

385    539    616

There are 616 total students
