-5 is the correct answer for this!
Answer: 9) when water is put inside a pot and put on a stove, the fire heats the pot, heat is transferred through the pot by conduction, the next step here in heat transfer by convection which happens in the water in the pot, when heat is transferred from the pot to the water the water molecules gain kinetic energy and moves up while the heavier molecules of the water comes down to get heated, this continues until heat is transferred throughout the water by convection, radiation occur when the quantity of the water is getting reduced.
10) same principle applies to that of the stove, but the difference is that the heat comes from sun and not from fire, the ice-cream is heated by conduction and heat is spread throughout the ice cream by convection , and radiation comes from the sun to the ice cream
Explanation:
Answer:
C. 600 N
Explanation:
Given,
mass of object (m)= 300kg
acceleration(a) =2m/s^2
We know that,
Force(F)=ma
=300*2
=600N
So,600N force is required to give an object.
