law of conservation of energy states that the total energy of an isolated system remains constant; it is said to be conserved over time.
Answer: 6000N/m^2
Explanation:
Weight =1500N
Area =0.5m^2
Pressure =1500/(0.5^2)
=6000N/m^2
Note: Newton is denoted by 'N' (Capital) and use '^' for powers.
Answer:
The velocity of water at the bottom, 
Given:
Height of water in the tank, h = 12.8 m
Gauge pressure of water, 
Solution:
Now,
Atmospheric pressue, 
At the top, the absolute pressure, 
Now, the pressure at the bottom will be equal to the atmopheric pressure, 
The velocity at the top,
, l;et the bottom velocity, be
.
Now, by Bernoulli's eqn:

where

Density of sea water, 



The answer i got was c. gravity and strong
i hope it helps
