Answer:
The area under a velocity-time graph is the displacement. Velocity can be negative if an object is moving backwards. The displacement can also be negative. An area beneath the x-axis has a negative value.
Answer:
P = 2.91*10^{-24} kg m/s
size of atom hat lie in range of 1 to 5 Angstrom
Angstrom
Explanation:
A) MOMENTUM
p = mv
where m is mass of electron
so momentum p can be calculated as
p = 9.11*10^{-31} *3.2*10^{6}
P = 2.91*10^{-24} kg m/s
b) wavelength
where h is plank constant
so
c) size of atom hat lie in range of 1 to 5 Angstrom
d) from the information given in the question we have
we know that
[]
Angstrom
supply it with more energy. one way to do is to produce vibrations in the same frequency as the wave. This would cause resonance leading to higher amplitude
