Answer:
Explanation:
As per Kepler's III law we know that time period of revolution of satellite or planet is given by the formula
now for the time period of moon around the earth we can say
here we know that
= mass of earth
Now if the same formula is used for revolution of Earth around the sun
here we know that
= mass of Sun
now we have
<h2>
Answer:Radiation-3,Conduction-1,Convection-2</h2>
Explanation:
Radiation is the transfer of heat through electromagnetic waves.
These waves do not require any medium.This is the way we get heat from sun.Radiation is the quickest mode to transfer of heat.
Conduction is the transfer of heat through collisions of atomic particles.
This phenomenon largely occurs in solids like metals.The neighbour atoms sets the atoms into random motion thereby raising the temperature.
Convection is the transfer of heat through actual movement of medium particle.
This phenomenon occurs in gases an liquids.The medium particles actually traverse through the space transferring the heat.
