When an isolated conductor is placed in the vicinity of a positive charge, it undergoes electrostatic induction: because of the presence of the near positive charge, the charges on the conductor redistribute, such that the negative charges move on the side of the conductor closer to the positive charge (because opposite-sign charges attract each other), while the positive charges of the conductor are repelled to the opposite side of the conductor (because same-sign charges repel each other)
Answer:
8m/s^2
Explanation: Acceleration is the rate of change of velocity per unit of time.
Hence, mathematically
Acceleration = {Velocity(meters/second)}/ time(seconds)
This means that
{40(m/s)}/(5 sec)
=8m/s^2
Change in pressure : 772-753 = 19 mm Hg
Since 1 mm Hg = 133 Pa Hg
Then, 19 mm Hg = 2527 Pa Hg
Area of rectangular pool = L* B = 11 x 21 = 231 m^2
To find the force, we multiply the area by the change in pressure: 2527 (231) = 583737N
C, it is the only logical choice, and if it were to get further away like that earth would no longer support life.
