Answer:
3.7 N/kg
Explanation:
The gravitational strength refers to the amount of gravity acting per unit mass. Hence in this case,
Gravitational Strength = Weight / Mass
= 370 / 100
= <u>3</u><u>.</u><u>7</u><u>N</u><u>/</u><u>k</u><u>g</u>
The answer should be the letter C...
That is -300 J, because the work = the force times the distance. When the distance is a positive value when it is going down, the distance is a negative value when it is going up. The only thing that change is the minus, the absolute value of the work remains the same
Answer:
Explanation:
Given
length=8 m
width=4 m
deep=4 m
Area of base 
hydro static Pressure on bottom

Force on bottom
Now pressure at the side wall

where
is the mean length of wall = 4 m
