Answer:
The angle of launch of the rubber band affects the initial velocity. The more the rubber band is stretched the more force it applies to return to equilibrium and the more kinetic energy that results in.
Answer:
-24.76 kJ/mol
Explanation:
given,
mass of solid magnesium burned = 0.1375 g
the temperature increases by(ΔT) 1.126°C
heat capacity of of bomb calorimeter (C_{cal})= 3024 J/°C
heat absorbed by the calorimeter




heat released by the reaction


energy density will be equal to heat released by the reaction divided by the mass of magnesium
Energy density = 
Energy density = -24.76 kJ/mol
heat given off by burning magnesium is equal to -24.76 kJ/mol
The anwser is c there is a light house near by
12 increase When force is multiplied by the distance over which it is applied, that amount is given ... force * distance = work
