Answer:

38.4 N.

Explanation:

From pascal's principle,

Pressure applied to the first piston = pressure applied to the second piston

F1/A1 = F2/A2 ....................... Equation 1

Where F1 = Force applied to the first piston, A1 = Area of the first piston, F2 = force applied to the second piston, A2 = Area of the second piston.

But,

A1 = πd₁²/4................... Equation 2

A2 = πd₂²/4............... Equation 3

Where d₁ and d₂ are the diameter of the first and second piston respectively.

Substitute equation 2 and equation 3 into equation 1

F1/πd₁²/4 = F2/πd₂²/4

F1/d₁² = F2/d₂² ................. Equation 4

make F2 the subject of the equation,

F2 = (F1×d₂)/d₁²................ Equation 5

Given: F1 = 240 N, d₁ = 4 cm, d₂ = 10 cm.

Substitute into equation 5

F2 = (240×4²)/10²

F2 = 38.4 N.

stepan [7]

Answer:

A fair test.

Explanation:

Hi, a fair test is used to do scientifically valuable experiments, is a controlled investigation to answer a scientific question.

In a fair test two or more things are compared.

It consists in changing only one factor (the one bieng tested) and keeping all the other conditions the same during an experiment.

The factor is called a variable.

Yolanda is studying two waves. The first wave has an amplitude of 2 m, and the second has an amplitude of 3 m. Which statement a
Anna71 [15]

Answer:

a) Not Accurate

b) Not Accurate

c) Accurate

d) Accurate

Explanation:

Part a

Not Accurate, because destructive interference would lead to maximum possible magnitude of < 3 m

Part b

Not Accurate, because constructive interference would lead to minimum possible magnitude of > 2 m

Part c

Accurate, because destructive interference would lead to maximum possible magnitude of < 3 m by varying the phase difference between two waves she can achieve the desired results.

Part d  

Accurate, because constructive interference would lead to minimum possible magnitude of > 2 m by varying the phase difference between two waves she can achieve the desired results.
