Answer: The handle of a frying pan on the stove
Explanation: Convection is the heat transfer done by the movement of a fluid, or the molecules on it. This can happen by the change on density from fluids, when a fluid tempeture rise, it expands, rising his volumen and decreasing his density. When this happens the fluid becomes lighter, so it moves.
The handle of a frying pan gets hotter but no molecular movement is done. It is between the same material there is a energy transfer from the source to the rest of the pan. This is called Conduction.
1.2 in still water would be 1.2-0.5 upstream
0.7 ups
1.7 downs
r = distance of moon from earth = 3.84 x 10⁸ m
R = size of the object on moon = 0.67 m
D = diameter of the lens = ?
= wavelength of light = 550 x 10⁻⁹ m
Using the equation for Rayleigh criterion
R/r = 1.22
/D
inserting the values
0.67/(3.84 x 10⁸) = 1.22 (550 x 10⁻⁹) /D
D = 384.6 m
The net force is 12 N to the left.
