We can solve the problem by using the first law of thermodynamics, which states that:
where
is the change in internal energy of the system
Q is the heat absorbed by the system
W is the work done by the system
In our problem, the heat absorbed by the system is Q=+194 kJ, while the work done is W=-120 kJ, where the negative sign means the work is done by the surroundings on the system. Therefore, the variation of internal energy is

Answer:2.81 m
Explanation:
Given
speed(u)=13 m/s
dart strikes 0.23 m below
i.e. vertical distance traveled by dart is 0.23 m
considering dart motion similar to Projectile
Horizontal distance travel by dart =u\times t
