A cylinder is fitted with a piston, beneath which is a spring, as in the drawing. The cylinder is open to the air at the top. Fr
maw [93]

Answer:

x = 0.081 m.

Explanation:

a) To find how much does the atmospheric pressure cause the spring to compress we need to use the following equation:

F = k*x    (1)

<u>Where</u>:

F: is the force

k: is the spring constant = 3300 N/m

x: is the distance of compression =?

The force can be found as follows:

F = P*A    

<u>Where</u>:

P: is the atmospheric pressure = 101325 Pa

A: is the area of the piston = πr²

r: is the radius = 0.029 m

F = 101325 Pa*\pi*(0.029 m)^{2} = 267.7 N    

Now, from equation (1) we can find x:

x = \frac{F}{k} = \frac{267.7 N}{3300 N/m} = 0.081 m    

Therefore, the atmospheric pressure causes the spring to compress 0.081 m.      

I hope it helps you!

the universal law of gravitation states that the force of attraction between two objects depends on witch quantities?​
Temka [501]

The equation is Fg = G(m₁m₂/d²).

G is the universal gravitational constant, but that isn't exactly a quantity.

m₁ and m₂ are the masses of the two objects, and those are quantities.

d is the distance between the two objects, and those are quantities.

So, masses and distance.

The atmosphere of Mercury and Mars are very thin. What effect does the thin atmosphere have on the temperature on the surface of
KengaRu [80]

Answer:

Very hot during the day and very cold at night.

Explanation:

Due to the thin atmosphere, they have very hot climate during the day time and very cold climate at night. This happens because they contain very low amounts of greenhouse gases. These gases retain the heat at night. The atmosphere also prevents excessive light and UV rays from entering. The thin  atmosphere leads to many asteroids and comets hitting the surface of the planet. On earth, these asteroids usually, burn up in the mesosphere layer of the atmosphere. These asteroid collisions cause massive fires. This in turn,  causes the temperature to increase during the day. During the night time, massive fires cannot burn due to the low temperature because of the lack of greenhouse gases.
