Answer:
1.51×10^58 moles of photons
Explanation:
n = E/hf
E is total energy = 1×10^44 J
h is Planck's constant = 6.634×10^-34 Js/mol
f is frequency of radiation = 1×10^19 Hz (1×10^19 s^-1)
n = 1×10^44/(6.634×10^-34 × 1×10^19) = 1×10^44/6.634×10^-15 = 1.51×10^58 moles of photons
Frequency has the unit hertz.
Centrifugal force is not a real force.
When you move around a curve, there IS a real force pulling you
around the curve. Since your body wants to go straight, it feels as if
there's a force trying to pull you away from the curve. But there isn't.
That feeling of a force is greater when your speed around the curve
is greater, or when the curve is tighter, i.e. smaller radius.
