I do, and my brother and son-in-law can also solve it.
Note: V1, V2, V3, I1, I2, and I3 are not labeled in the picture, so those can't be solved for.
Answer:
X-ray Telescope
Explanation:
X-ray Telescope which can be either hard or soft is an instrument on an orbiting satellite that would detect the flare first.
This is because X-ray Telescope is technically designed to detect and determine X-rays or radio and optical emissions from flares, from places or points beyond Earth's atmosphere.
Answer: Find the answer in the explanation
Explanation:
Bohr postulated that :
1.) Electrons revolve in specific circular orbits around the nucleus and these orbits can be represented by the letters K, L, M, N.
2.) Electrons revolving in a particular orbit are in a stationary state. They can neither gain energy nor loose energy. 3.) But if an electron jumps from an higher orbit to a lower orbit it will emit energy in the form of radiations. Also if an electron jumps from lower orbit to a higher orbit it excites and absorbs energy in the form of radiations.
4.) Neil Bohr experimental findings about angular momentum of an electron shows more light on the stability of atom and the line spectrum of hydrogen atom
