None of the energy is created nor destroyed
Answer:
False
Explanation:
From the fact that light is emitted in portion, it does not follow that light ray is discrete in structure.
The way Einstein put it was that if a beer is always sold in pint bottles, that does not mean that beer contain of indivisible pint bottles. Yet experiments in which light knocked electrons out of materials insistently made the point that light is absorbed only in the form of discrete portions. An emitted portion or quantum of light energy retains it's individuality in subsequent events as well.
This concept was first stated by Einstein in 1905. From the heuristic point of view that he developed light is always made up of discrete portions possessing energy and momentum.
Answer:
The lines slope up from the red ball to the corresponding blue ball.
Answer:
7.65 m
Explanation:
= Initial pressure = 0.03 atm
= Final pressure = 1 atm
= Inital radius = 21 m
= Intial volume of gas = 
= Final volume of gas = 
= Initial temperature = 200 K
= Final temperature = 323 K
From ideal gas law we have
The radius at liftoff is 7.65 m
Answer:
Explanation:
Position of the ball as a function of time is given as
now we know that when ball will attain maximum height then the differentiation of the position with respect to time will become zero
so we have
now the maximum height is given as
