Answer : The kinetic energy will be 24 J.
Explanation : Given,
Mass of marble = 3 kg
Velocity of a marble = 4 m/s
Formula used to calculate the kinetic energy is:
where,
K.E = kinetic energy
m = mass
v = velocity
Now putting all the given values in this formula, we get:
Therefore, the kinetic energy will be 24 J.

Answer: d) -705.55 kJ
Explanation:
Heat of reaction is the change of enthalpy during a chemical reaction with all substances in their standard states.
Reversing the reaction, changes the sign of
On multiplying the reaction by , enthalpy gets half:
Thus the enthalpy change for the given reaction is -705.55kJ
