What happens if we cover 1 slit in the experiment? Will it become a single slit experiment?

Pressure=height x density x g and pV = constant ?

Pressure=height x density x g and pV = constant ?

Hi BvU, It's in an examination paper which consists of many problems from random topics so I'm afraid we will have to figure out the solution.

Homework Statement A vessel of internal volume 9 m^3 is lowered with its mouth downward into fresh water lake until the volume of the air in the vessel becomes 5 m^3. Given that the atmosphere pressure is 760 mmHg, what is the verrtical distance of the water level inside the vessel from the...

Why does the temperature of boiling or melting water remain constant?

Now it's too much for me :D but thanks anyway.

Coukd I ask one more question : how about the period of 3 identical planets moving around another planet and they are positioned one third of a revolution apart from each other? Do we have consider the force between the three planets or just simply the force between them and the planet in the...

Thanks everybody. It turn out to be not as complicated as I think it is :D

I still don't knowhow to apply Kepler's Law to this problem. I can mathematically prove the Kepler's Law in case of satellite moving around Earth but with 2 planet in circular orbit I have no idea. Can you please explain a bit further and use the equation so that it would be easier for me to...

Can you explain a bit further please, how does it relate to the Kepler's law. I thought their must be something to do with the gravitational force

Homework Statement Two stars of masses M and m, separated by a distance d, revolve in circular orbits around their center of mass.Show that each star has a period given by T^2= (4π^2)(d^3)/ G(M+m) Homework Equations [/B]The Attempt at a Solution I[/B] know the Kepler's Laws can be...

I'm studying A level Physics myself and they are quite different from Physics in my own langluage so I am not really confident. :D

It is D

Thanks. I'm just not confident enough to say so :D
