Answer: Not 100% sure but I believe the answer is B.
Hope this helps! ^^
Molten rock material wells up from the underlying mantle into the gap between the diverging plates and solidifies into oceanic crust, thereby creating new ocean floor. At the deep-sea trenches, two plates converge, with one plate sliding down under the other into the mantle where it is melted.:)
To solve this problem we will apply the concepts related to classical mechanics, for which we will first consider the general equation that describes the movement of the body. From there, as we well know, we will obtain the derivative, which is equivalent to the speed of the body and the rate of change that is investigated in the problem.
Our values are given as,
We will start by defining the general height 'y' of the body at a reference distance of the lifting copter, given as
Differentiating both the sides we have
Now when the altitude of the copter is 124ft we have that
And,
Using these values at the derivative equation finally we have that
Therefore the distance between the man and the helicopter is increasing at the rate of 40.68ft/s
Explanation:
It is given that,
Wavelength of red light,
Power of the laser,
(a) The energy carried by each photon is given by :
(b) Let n is the number of photons emitted by the laser per second. It can be calculated as :
Hence, this is the required solution.
Answer:
They both create energy for daily use.
