Answer: Well we see that v= u- ft/m
lets say that ft= feet and m= mass
so you divide those and subtract u
leaving you with the value of v which is 13
Collecting light and bringing it to focus.
When water changes from a liquid state to a solid state, the process is called solidification (freezing), this change in matter strengthens the intermolecular forces of the molecules and is hence an exothermic reaction, which releases energy.
When water changes from a liquid state to gaseous state, the process is called evaporation (vaporization), this change in matter weakens the intermolecular forces of the molecules and is hence an endothermic reaction, which absorbs (uses) energy
