False............ It is in both directions in the form of centri-petal & fugal towards inwards and outwards respectively....
B. An increase in your mass
Because acceleration is inversely proportional to the mass of the object.
Answer:
99.88 or 100g
Explanation:
The heat required to melt the snow to water and rise it boiling point we consider
1. The heat required to convert the snow to water at the same temperature. This heat is referred to as latent heat of fusion given as
H= mass of the snow or ice (m) x specific latent heat of fusion of ice (l) = ml
2. The heat required to rise the water temperature to it's boiling point
Given by
H= mass of water x specific heat capacity of water x change in temperature = mc(T2-T1)
That give
H= ml+mc(T2-T1)
making m subject of formula gives
H= m(l+c(T2-T1))
H=643KJ, l=6.02KJ/mol, c=4.18J/g, T1=0,T2=100
Substituting values
643*1000= m(6.02*1000+4.18*(100-0))
643000=m(6438)
dividing both side by 6438 give
m= 99.88 or 100g
