Answer:
P=F/A where F is the weight of the water and A is the area on which it is resting. The weight of the water is mg. The mass of the water is dv where d is the density and v is the volume. Finally, the volume of the water in a vessel is equal to the area of the base of the vessel times the height of the vessel. (v=Ah)
Plugging everything in we get:
P = dAhg/A
So
P=dhg
So we have shown that liquid pressure is directly proportional to height of liquid in a vessel.
Momentum = (mass) x (speed)
Momentum = (12,000 kg) x (40 m/s)
Momentum = (12,000 x 40) kg-m/s
<em>Momentum = 480,000 kg-m/s </em>
Answer:
The answer is A.) Mass is a measure of the amount of matter in an object, while weight is a measure of the force of gravity on the object.
Explanation:
Your weight would change if you went to the moon because the gravitational pull is different but your mass would stay the same because the amount of matter in you wouldnt change.

B It’s a physical change because the water and the salt kept their original properties.</span>
