The normal force is greater than the weight of the block.
Explanation:
How does the magnitude of the normal force exerted by the ramp in the figure compare to the weight of the static block? The normal force is greater than the weight of the block. Possibly greater than or less than the weight of the block, depending on whether or not the ramp surface is smooth. Equal to the weight of the block , possibly greater than or equal to the weight of the block.
The radiation fog is formed when the land surface cools after the sunset in the conditions of the clear sky. Thus the cooling ground cools the air above it and as a result of this the conduction causes the air temperature to fall and hence it reaches the dew point and forms a fog.
