Answer:
F = 1250000 N
Explanation:
If you have 50,000 S, by 25 M. It would be calculated to 1,250,000 N.
Answer:
energy transform mechanical to motion
Answer:
the x and y values
Explanation:
because on the table the x is the input and y is the output
We want to find how many photons per second a laser emits given that we know the energy of a single photon and the power of the laser, we will get:
1.90712*10^18 photons per second.
So we know that the photon energy is 1.8 eV, and the laser power is:
P = 0.55 watts
Remember that:
1 watt = 1 J/s
And:
1 eV = 1.60218*10^(-19) J
Then we can convert the two values that we have so we have both in joules:
Power = P = 0.55 J/s
Energy = 1.8 eV = 1.8*(1.60218*10^(-19) J) = 2.883924*10^(-19) J
The number of photons emitted per second is just the quotient between the power and the energy of a single photon, we have:
Number = (0.55 J/s)/(2.883924*10^(-19) J) = 1.90712*10^18 photons per second.

Answer:
n = 1.5
Explanation:
The speed of light in vacuum is 300000000 m/s
The speed of light in glass is 200000000 m/s
We need to find the refractive index of the glass.
We know that, the ratio of speed of light in vacuum to the speed of light in medium is equal to refractive index of the medium.

So, the refractive index of the glass is 1.5.
