Answer: C
Explanation: On the top edge.
The force of friction on the box is 8.82 N.
The force of friction is given by the formula
F=μN
Here N is the normal force of the box=mg=3*9.8=29.4 N
Now the static friction force on the box is=0.4*29.4=11.76 N
Since the box is applied with the horizontal pull of 15 N, which is greater than the static friction, therefore the box must be in the moving condition, in that case there is dynamic friction force is applied on the box=0.3*29.4=8.8 N
Therefore the force of friction on the box is 8.8 N.
While walking to work in Boston shortly after sunrise you notice that the water level in the bay is exceptionally low. Based on this very low low-tide and the dark cloudless sky last night, the current phase of the moon is a waxing crescent. Among the 8 phases of the Moon, the waxing crescent follows the new-moon phase.
The phases of Moon happen because of the presence of moon's orbit between the Earth and the Sun. The surface of the Moon reflects sunlight and this light reaches the Earth at different angles depending on the location of the Moon in its orbit. This gives us the impression of a waxing and a waning Moon.
