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.
The heavy man will fall faster, because he has more mass and heavy things fall faster than light things

Answer:
Explanation:
We shall consider the balance of forearm . The weight is balanced by tension created in the bicep of forearm.
The weight of forearm will act downward . Let it be W. Tension T of bicep will pull the forearm upwards . Bicep muscle is attached at a point between palm and elbow. Its other end is attached with hind arm . If we hold the forearm parallel to ground , weight acts vertically downwards and tension in bicep makes some angle with the vertical . Let it be θ.
Vertical component of tension T
= T cos θ . It will balance W .
T cos θ = W
T = W / cos θ
the value of cos θ will always be less than 1.
so T > W . or
tension in bicep is more than weight of forearm.
