It is an example of personification because personification is when human traits are give to non human things. Sky's cannot cry.
Answer:
It increases.
Explanation:
For the electron to escape the photon needs energy is equal to the difference between initial and its non quantised region energy , then only it will be able to escape finite well.
E ∝ n^2
n= energy state quantum number
so if , n increases maximum point of probability density increases.
Explanation:
Below is an attachment containing the solution.
Temperature and pressure can change the solubility of a solute.
125 W is the power output of this machine.
Answer:
Explanation:
Power is defined as the amount of work done on the system to move that system from its original state within the given time interval. So it can be determined by the ratio of work done with time interval. As work done is the measure of force required to move a system to a certain distance. Work done is calculated as product of force with displacement.
So in the present case, the force is given as 100 N, the displacement is given as 5 m and the time is given as 4 s, then power is

As Work done = Force acting on the machine × Displacement
So 
Power =
=125 W
So, 125 W is the power output of this machine.
