A convex mirror makes a reflected light rays spread out.
If the Earth didn't tilt then we wouldn't have seasons.
A). No. A mirror doesn't separate light into its different wavelengths.
B). No. Light doesn't separate into its different wavelengths when it
goes, say, from glass into water.
C). No. When light goes through your glasses, it doesn't separate
into its different wavelengths.
D). Yes ! When sunlight shines into droplets of water in the atmosphere,
it comes out separated into its different wavelengths. When we see that
happening in the air in front of us, we call it a "rainbow".
One is when you are measuring a distance in space! I don't know the other but hope you find another example!
W = 980N. The weight of an object of 100Kg in the Earth is 980N.
The weight is a measure of the gravitational force acting on an object, the weight is equivalent to the force exerted by a body on a point of support, caused by the action of the local gravitational field on the mass of the body.
it can be defined as the product of mass by the acceleration of gravity, w = mg. Since weight is a force, its unit is the Newton N.
If the mass of an object on earth is 100 kg, then is weight is:
W = (100Kg)(9.8m/s²) = 980N.
