Answer:
Archimedes principle: volume of water displaced by immersed object is equal to volume of water.
so if two object has same volume but different mass
then density determines the flotation of object,if an object has more density than water then it sinks.
I think this is called as special condition of floatation.
for any ray on the mirror, incident angle - reflected angle.
angles wrt a normal to mirror
A common example of radiation would have to be sunlight
(1) Scientists generally agree that Earth is getting warmer due to what's called the greenhouse effect. (2) A greenhouse stays warm because sunlight and heat coming through the glass roof are mostly trapped. (3) The heat doesn't radiate back into the atmosphere because it's held in by the glass. (4) Something like that happens on Earth. (5) The atmosphere acts like a blanket that keeps the Sun's heat from leaking away into space.
What is the main conclusion you are to draw from this paragraph?
A. The atmosphere is what keeps the planet warm.
B. The greenhouse effect is changing Earth's atmosphere.
C. The sun's heat can easily leak away out into space.
D. Greenhouses help most plants to grow more quickly.
