Formula for time
t=d/s
so…
t= 48m/4m/s
the two ms cancel each other out and ur left with s
t=12s
A. Radioactive decay does not result in heat. Gravity also does not result in heat. In the Earth's mantle, it is highly unlikely that the radiation from the sun would reach that deep into the earth.
To develop this problem it is necessary to apply the concepts related to the calculation of the Force through density and volume as well as the ideal gas law.
By definition, force can be expelled as
F = ma
Where,
m = mass
a = Acceleration
At the same time the mass can be defined as function of density and Volume
Therefore if we do a sum in the spherical balloon we have,
Where,
= Force by weight of balloon
= Force by weight of helium gas
= Buoyant force
Re-arrange to find
Our values are given as,
Replacing the values we have,
Applying the ideal gas law we have finally that
Where,
P = Pressure
Density
M_0 Molar mass (0.004Kg/mol for helium)
R= Gas constant
T = Temperature
Substituting
Therefore the absolute pressure of the helium gas is
Well, they are equal and opposite, but the force is high enough to break up the snowball. That is where the energy is dissipated.
