'D' would do the job ... When you subtract the protons from the mass,
what you have left is neutrons. (The electrons can be ignored. It takes
around 1840 electrons ! to add the mass of a single proton or neutron !)
I don't know it for a fact, but I'd be surprised if the process is really that
simple. I mean, it starts out with knowing the atomic mass, and then
knowing the number of protons in the nucleus. Each of those is a
whole complex problem in itself.
The energy of a single photon at the transmitted frequency is
Answer: Option b
<u>Solution:</u>
Energy of photon is given as
Where c is the velocity of Light
h is planck's constant
λ is the wavelength of photon
Energy of photon can be rewritten as
Where f is the frequency of photon
Frequency of photon is obtained by dividing velocity of light by wavelength of photon.
Answer:
Aluminum foil is a physical change. A further explanation is given below.
Explanation:
- The processing of aluminum foil starts with either a succession of cool rolling procedures, wherever another density including its aluminum alloy becomes diminished by half amongst every method.
- Aluminum foil modified thickness and weight, but it would be an aluminum sheet, so it would be a physical transition or change.
