I don't completely understand your drawing, although I can see that you certainly
did put a lot of effort into making it. But calculating the moment is easy, and we
can get along without the drawing.
Each separate weight has a 'moment'.
The moment of each weight is:
(the weight of it) x (its distance from the pivot/fulcrum) .
That's all there is to a 'moment'.
The lever (or the see-saw) is balanced when (the sum of all the moments
on one side) is equal to (the sum of the moments on the other side).
That's why when you're on the see-saw with a little kid, the little kid has to sit
farther away from the pivot than you do. The kid has less weight than you do,
so he needs more distance in order for his moment to be equal to yours.
Asteroids are too small to have atmospheres
Answer:
Attractive Property – Magnet
Explanation:
attracts ferromagnetic materials like iron, cobalt, and nickel. Repulsive Properties – Like magnetic poles repel each other and unlike magnetic poles attract each other. Directive Property – A freely suspended magnet always points in a north-south direction.
Answer:
The wavelength of observed light on earth is 568.5 nm
Explanation:
Given that,
Velocity of spaceship 
Wavelength of laser 
We need to calculate the wavelength of observed light on earth
Using formula of wavelength






Hence, The wavelength of observed light on earth is 568.5 nm
