Answer:

At the time of sunrise, Sun appears above the horizon 2 minutes earlier than it really is, because when the light moves from the sun to earth it trave across different atmospheric zone and the density of atmosphere zone increases as the distance decreases from the earth. So incoming light rays bents toward the earth. this bending of light makes a virtual image of Sun above the horizon and we feel like sunrise. similar things happen at the time of sunset and sun appears 2 minutes after the actual sunset. So the total duration of Sun appears above the horizon is approx 4 minutes higher than it really is.

A force acting over a large area will exert less pressure per square inch than the same force acting over a smaller area.
babunello [35]

Answer:

True

Explanation:

Pressure is defined as:

p=\frac{F}{A}

where

F is the magnitude of the force perpendicular to the surface

A is the surface

Therefore, pressure is inversely proportional to the area of the surface:

p\propto \frac{1}{A}

this means that, assuming that the forces in the two situations (which have same magnitude) are both applied perpendicular to the surface, the force exerted over the smaller area will exert a greater pressure. Hence, the statement"

<em>"A force acting over a large area will exert less pressure per square inch than the same force acting over a smaller area"</em>

is true.
