The total force applied by the three people is:
This force is pushing toward the direction of the motion, while the frictional force
points in the opposite direction.
We can write Newton's second law applied to the block: the resultant of the two forces must be equal to the product between the block's mass and its acceleration
We know the mass of the block, m=500 kg, and the acceleration,
, so we can find the friction:

3)
4) The Molecules do not burn because of the presences of hydrogen bond in place
Explanation:
From the question we are told that
latent heat of vaporization for water at room temperature is 2430 J/g.
1)Generally in determining the molar mass of water evaporated we have that
-One mole (6.02 x 10. 23 molecules)
-Molar mass of water is 18.02 g/mol
Mathematically the mass of water is give as
Therefore
b)Generally the evaporation speed V is given as
Mathematically derived from the equation
To Give
c)Generally the equation for velocity
Therefore
Effective temperature T is given by
where
4) The Molecules do not burn because of the presences of hydrogen bond in place
