As we know that the dimensions of the base of the tank is given as
now the base area is given as
now we know that volume of the liquid filled in the tank is given as
now we will differentiate it with respect to time both sides
here we know that
now we have
Newtons Second Law states that objects in motion, stay in motion. Seat belts are there to restrain you from moving out of your seat in the incident of a car crashing. Therefore, Newtons Second Law applies to seat belts because they are there to stop you from being in motion with the car, thus not letting you go through the window or hitting your head.
Answer:
a. Point A
b. 20 V
c. 100 J
Explanation:
a. Point A is at a higher potential because there is a positive sign in front of its magnitude. Since it is a positive integral value, and has a higher magnitude than point B which is at -4, point A is thus at a higher potential than point B.
b. The potential difference between the two points ΔV = A - B
= +16 V - (-4 V)
= +16 V + 4 V
= + 20 V
c. The work done, W in moving a charge Q across a potential difference ΔV is W = QΔV
So, since Q = 5 C and ΔV = + 20 V
W = QΔV
= 5 C × (+ 20 V)
= 100 J
