Answer:
i think it is texture and composition
force applied due to earth on the apple is given as
given that
m = 0.37 kg
a = 9.8 m/s^2
now we have
now as per Newton's III law equal and opposite force is applied on earth
so now we can find acceleration of Earth using same equation as we used above
here we know that
m = mass of earth
F = 3.63 N
so acceleration of earth is very small and given by above value
Answer:
Answer: The height of the apple from the ground is at 49552.61071 m or is approximately at 5.0 × 10 m.
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.
