After a party the host pours the remnants of several bottles of wine into a jug. He then inserts a cork with a 2.15-cm diameter

pychu [463]

Answer:

3893.99675 N

Explanation:

$F_1$ = 125 N

$A_1$ = $\pi 1.075^2$

$A_2$ = $\pi 6^2$

From Pascal's law

$\dfrac{F_1}{A_1}=\dfrac{F_2}{A_2}\\\Rightarrow F_2=\dfrac{F_1\times A_2}{A_1}\\\Rightarrow F_2=\dfrac{125\times 6^2}{1.075^2}\\\Rightarrow F_2=3893.99675\ N$

The force that the liquid exerts on the bottom of the bottle is 3893.99675 N

A toy dart gun has a spring with k= 128 N/m. How much force does it take to pull the spring back 0.0500 m? (Unit = N)

yKpoI14uk [10]

Answer:

F = 0.64 N

Explanation:

We are given;

Spring constant constant; k = 1.28 N/m

Distance; x = 0.5 m

From Hooke's law, we know that F = kx.

Thus;

F = 1.28 × 0.5

F = 0.64 N

Thus, force it takes to pull the spring back = 0.64 N
