Answer:

Machine C is producing maximum power

Explanation:

As we know that power is defined as rate of work done or rate of energy produced.

Power = \frac{Work}{time}

Here it is given that we have three machines A , B  and C

All three machines are doing same amount of work but the time taken by the machines is different.

Here given that maximum time is taken by machine B and then out of A and C it is given that machine A took more time than machine C.

So here we know from above relation that lesser the time more will be the power so here maximum power is due to Machine C as it is doing same work in least amount of time.

So power is considered as the rate of doing work. Base on the problem given, my analysis is that the machine who finish the work faster is machine C. Therefore, in order to finish the same amount of work in a short period of time you are going to expend the most power. My answer is Machine C.

Wavelength of blue photons 495 nm, what is the frequency? and what is the energy?
inessss [21]

Answer:

1.F: About 6*10^14 Hz

2.E: About 4*10^ -19 J

Explanation:

Frequency: We knew that the speed of a wave is its wavelength(λ)* frequency(f, in Hz).  By the wave-particle duality we know we can calculate the frequency of light in the same way. So, c=495nm *f, f=c/495nm=> (299,792,458 m/s) / (4.95*10^-7 m)

=6.05*10^14 /s

Energy: The energy photon contains can be calculate by this formula-- E=hf

f is the frequency and h is Planck's constant which is about 6.62 ×10^-34 *m^2*kg/s (after dimensional analysis ) =6.62*10^ -34 J*s.

So, the energy of a blue photon is (6.05*10^14)*(6.62*10^-34)=40.051*10^-20=  4.051*10^-19 J
