<span>Objective Lenses: Usually you will find 3 or 4 objective lenses on a microscope. They almost always consist of 4X, 10X, 40X and 100X powers. When coupled with a10X (most common) eyepiece lens, we get total magnifications of 40X (4X times10X), 100X , 400X and 1000X.</span>
As we know that spring force is given as
here we know that
F = 4 N
x = 2 cm = 0.02 m
now from the above equation we will have
so the elastic constant of the spring will be 200 N/m
Answer:
yeah physical quantities are the quantities which can be meaured
So the heavy skateboarder will move off with speed 2.45 m/s in the opposite direction
Answer:
A frame of reference is the location from which motion is perceived and measured. For all observers, the speed of light remains constant.
