Answer:

Explanation:
As we know that base of the slab is given as


now we know that rate of heat transfer is given as

here we know that

Also we have



Answer:
Radiation heat energy transfer
Explanation:
The type of heat transfer from the Sun is radiation heat transfer, which is the transfer of heat through electromagnetic radiation
The distance of the Sun to the Earth is several million kilometers away, with the space between being composes of vacuum and the nuclear reaction in the Sun's core generates vast amount of electromagnetic radiation that is transferred all across the universe and reaches the Earth as visible light and radiant energy at the speed of light
The radiant energy transferred from the Sun heats up the Earth, including the car's interior.
Answer:
Part a)

Part b)

Explanation:
Part a)
mass of the Falcon bird is given as

initial speed of the bird is

final speed of the bird is given as
(opposite direction)
So here the impulse given by falcon bird is given as



now the final momentum of Raven bird in perpendicular direction is given as



now the change in the angle of the raven bird is given as



Part b)
Final speed of the raven bird is given as
