The generation of a magnetic field by an electric current is _electromagnetism_.
Well Inertia means something wants to stay in place, and in reality that coin wants to stay in one place, If you placed it on an index card on a cup, and SLOWLY pulled it, it wouldn't be fast enough to overcome that force, if you pulled it quickly that coin would stay in place and drop into the cup.
Answer:
The Doppler shift may be helpful to determine the relative speed of an object by bouncing a wave (usually a radar wave) off the object and measuring the shift in the frequency of the wave.
Explanation:
Doppler shift helps to overcome a visual illusion block out irrelevant noises, locate sounds and see an object in very dim light by determining the relative speed of an object by bouncing a wave
Answer:
n = 19
Explanation:
= Wavelength of the light absorbed = 91.65 nm = 91.65 x 10⁻⁹ m
= nth level = n
= 1
Using conservation of energy
