Answer:
Option D 3.9
Explanation:
First, you need to use the correct equation which is the following:
COP = Q/W
Where:
Q = heat absorbed
W = work done by the pump
COP = coefficient of perfomance
We have all the data, so, all you need to do is replace in the above expression and you shoould get the correct result:
COP = 30 / 7.7
COP = 3.896
This result you can round it to 3.9. option D.
Answer:
A) being influenced by equal amounts of gravity and air resistance.
Explanation:
B) slowing down because of an unbalanced force of air resistance.
False - if it was slowing down, then the velocity would go down.
D) on the ground and is not falling anymore.
False - This would be mistaken as the answer but it is not because if the person is not falling anymore the horizontal line should be at the x-axis, meaning that there is no more velocity.
C) accelerating because of an unbalanced force of gravity.
False - The line would otherwise be going up or down.
Yes all those are correct, but I don't know what the question was
Answer: ok well first when Horizontal faults, like vertical faults, disturb the formation of the earth's layers and cause irregularities, including tilting. Surface fault ruptures can also cause tectonic subsidence, which is broad tilting of the valley floor. that is What causes the disturbance of rock layers to collapse what and then Due to an unconformity, the ______ period is missing from the rock layer record. The principle of lateral continuity proposes that sedimentary rock layers it provided a tool for sorting out the relative timing of various geologic events must have been moved into that position by crustal disturbances after their deposition.
