Answer:
u are falling
Explanation:
In Newtonian physics, free fall is any motion of a body where gravity is the only force acting upon it. In the context of general relativity, where gravitation is reduced to a space-time curvature, a body in free fall has no force acting on it.
Answer:
GPE is directly proportional to mass as
U=mgh
hence more mass more gpe
ans is one with 500N
Due to its polarity and hydrogen bonding water can absorb heat without a significant temperature change.. The high specific heat of water helps regulate the rate at which air changes temperature, which is why the temperature change between seasons is gradual instead of sudden, especially near the oceans.
Answer:
total amount of fluoride 3.6 *10^6 g
Explanation:
we know that
volume of reservoir 
=![\pi* [\frac{4.70*10^2}{2}]^2 *14.2](https://tex.z-dn.net/?f=%5Cpi%2A%20%5B%5Cfrac%7B4.70%2A10%5E2%7D%7B2%7D%5D%5E2%20%2A14.2)
= 2.25*10^6 m^3
denso=ity of water = 1000 kg/m3
mass of water = 1000*2.25*10^6
= 2.25*10^9 kg = 2.25*10^12 g
fluoride 1.6 ppm
total amount of fluoride 
= 3.6 *10^6 g
It releases carbon dioxide
