The ability to do work is called energy.
Answer:
C
Explanation:
Power is work divided by time:
P = W / t
Work is force times distance:
W = F d
Therefore:
P = F d / t
Given that F = 500 N, d = 60 m, and t = 240 s:
P = 500 N * 60 m / 240 s
P = 125 W
Answer is C.
1.What types of geological events or changes occur at divergent plate boundaries?
Volcanoes and minor earthquakes occur at divergent plate boundaries.
2. What types of geological events or changes occur at convergent plate boundaries? Volcanoes, earthquakes and fold mountains occur at convergent plate boundaries.
3. What types of geological events or changes occur at transform plate boundaries? Earthquakes and fold mountains occur at transform plate boundaries.
4. Explain how these geological processes and interactions have changed Earth's surface through the years. Magma from volcanoes is filled with nutrients that makes land fertile. Some earthquakes make the ground shake so violently that it destroys entire landscapes and environments. Earthquakes can also cause landslides and tsunamis, which destroy whole villages, change geology and ruin natural habitats of many living creatures. W<span>hen an earthquake happens in the middle of the ocean, it can create waves that are so large that they destroy coastlines, cities, and forests hundreds of miles away.</span>
just analyze it in this way:
