Radiation is a type of heat transfer wherein there is no need for medium or media through which the heat will flow. Consequently, the radiation waves are able to travel through vacuum. The best observation as evidence to conclude that heat is indeed transferred by radiation is the increase of temperature of the receiving body.
Mass is indirectly proportional to acceleration, so, lighter the object greater would be it's acceleration...
A) 0.10 kg is lightest among them, so it's your answer
Answer:
Rate of change of area will be 
Explanation:
We have given rate of change of radius

So 
Puting the value of r and 

So rate of change of area will be 
red goes to red, black goes to white, yellow goes to green, blue goes to blue.
