<span>Heat from the Sun is transferred to the sand without direct contact. This heat is then transferred to your feet by direct contact.</span>
Answer: In convection, there is a transfer of heat due to the bulk movement of molecules within the fluid. It affects our atmosphere, layers of earth and our ocean due to the temperature difference.
Explanation:
Convection is a transfer of heat due to bulk movement of molecules within the fluid.
Convection affects our atmosphere. There is a temperature difference in the atmosphere. Warmer air rises up in compare to the cooler air.
Convection affects our layers of earth. It is limited to troposphere. Due to the high transmission of clear sky to bulk incident energy from sun, troposphere is subjected to convection.
Convection affects our oceans. There will be temperature difference in the ocean water. When the water of ocean heats up then it becomes less dense.
That is false I think sorry if its not correct
Answer:
0.763 m
Explanation:
Intensity I = power P ÷ area A of exposure (spherical area of propagation)
I = P/A
A = P/I
Power = 10.0 W
Intensity = 1.39 W/m^2
A = 10/1.39 = 7.19 m^2
Area A = 4¶r^2
7.19 = 4 x 3.142 x r^2
7.19 = 12.568r^2
r^2 = 7.19/12.568 = 0.57
r = 0.753 m
Answer: uhhhhhhh what is this for?
Explanation i so confused
