Answer:
601 nm
Explanation:
Energy of photon having wavelength of λ nm
= 
eV
Energy of 249 nm photon
=
=4.996 eV
Similarly energy of 425nm photon
=
=2.927 eV
Difference = 2.069 eV.
This energy will give rise to another photon whose wavelength will be
λ = 
= 601 nm.
Answer:
9N
Explanation:
net force = right force - left force
net force = 22 - 13=9N
The frequency of any repeating event is the number of times it happens in some specified period of time.
The frequency of a wave is the number of cycles, wiggles, compressions etc. that occur in a given time, usually one second.
Answer:
bus
Explanation:
since the bus is hevier it has more kenetic energy than the cop car. to make it the same energy the bus would either slow down or the cop can speed up.
