Answer:
(B) Boundary work
(D) Heat
Explanation:
Boundary work and heat quantitatively describe the transition between equilibrium states of thermodynamic systems. They are not only a function of the initial and final states, but also of the successive intermediate states through which the system passes, this is, depend on the path taken to reach one state from another. Thus, are path functions.

law of conservation of mechanical energy
PE1 = Ek2
mgh=1/2mv²
h = 12 sin 60
Answer:
1.1x10^-2N
Explanation:
We have the change in momentum as
P = 0.3(4.5+12)g.mph
= 0.3x0.447x(4.5+12)x10^-3
Then the force that is exerted will be
F = p/∆t
∆t = 0.2
= 0.3x0.447x(4.5+12)x10^-3/0.2
= 0.1341x16.5x10^-3/0.2
= 1.1x10^-2
Therefore the force that was exerted is equal to 1.1x10^-2
