Answer:
energy cannot be created or destroyed
Explanation:
Energy can't be created nor destroyed; rather, it transforms from one form to another.
Answer:
The height of the bag is 1.466 m.
Explanation:
Given that,
Acceleration of gravity 
Pressure = 14800 Pa
Specific gravity = 1.03
We need to calculate the density
Using formula of specific gravity


Where,
= density of solution
= density of water
Put the value in to the formula


We need to calculate the height
Using formula of pressure


Where, P = pressure
g = acceleration due to gravity
h = height
Put the value into the formula


Hence, The height of the bag is 1.466 m.
Metals are dense because the molecules are tightly packed together, as opposed to non metal items where molecules are loose and separate. this is why metal is stronger than nonmetal items.
