Not if both speeds are in the same units.
However, if the 254 is 'centimeters per time' and the 100 is 'inches per time',
then the speeds are equal.
Answer:
The largest allowable Io = 5.863 * 10^26 photons
Explanation:
thickness of slab = 2.8 mm
First we express the energy of each photon
wavelength = 313 nm
attached below is the detailed solution on how i arrived at the answer above
note : we use 2 in the integral because the slab is exposed to light from two different direction
-- a party balloon that's full of helium and resting on the ceiling
-- a piece of styrofoam
-- a cloud of smoke
-- a bag of hot air
-- a cirrus cloud in the sky
I think it’s A sorry if wrong
