Answer:
36,000j
Explanation:
W= P•t
120•300= 36000
I checked my answer with P= W/t and got the right answer
hope this helps
Answer:
Can enter or leave the system matter and energy. (The correct option is D)
Explanation:
Open system is defined as the system where exchange of matter, and energy occurs with its surrounding, presenting breaking down, and build up of its materials, and import, export of components.
Open system transfer the material into, and out of the system boundary, it contains an external interaction. A good example of open system is living things they actively connect with its environment, in results it shows changes in both the environment, and the living things.
So, the correct option is D.
Answer:
Absorption, in wave motion, the transfer of the energy of a wave to matter as the wave passes through it. The energy of an acoustic, electromagnetic, or other wave is proportional to the square of its amplitude—i.e., the maximum displacement or movement of a point on the wave; and, as the wave passes through a substance, its amplitude steadily decreases.

Answer:
350 W
Explanation:
50 steps × 0.12 m/step = 6 m
Power = work / time
P = mgh / t
P = (60 kg) (9.8 m/s²) (6 m) / 10 s
P = 352.8 W
Rounding to two significant figures, the power is 350 W.
