In 1913, Niels Bohr proposed a theory for the hydrogen atom based on quantum theory that energy is transferred only in certain well defined quantities. Electrons should move around the nucleus but only in prescribed orbits. When jumping from one orbit to another with lower energy, a light quantum is emitted.
Answer:
A and C
Explanation:
drag (the area of lower air pressure behind the car when moving) and mostly air resistance (the work to push the air in front of us away to move through - the faster we go, the stronger the air resists to move aside).
<span>both the speed of the wave and the wavelength
- The frequency does not change, but the speed does. If that is true, then the wavelength must also change.</span>
vf=vi+at
No need for rearranging because it is already set up for Vf (final velocity)
a= -9.8m/s² (because it is falling)
vi= 0
t= 2.7
0 + -9.8(2.7) = vf
vf = -26.5 (-26.46)
Mainly it belongs in the deciduous forest biome. The U.S also includes the desert, tundra, and coniferous forest biomes.
Put this under 'Geography' next time.
Hope this helps!
