De broglie wavelength, 
, where h is the Planck's constant, m is the mass and v is the velocity.
Mass of hydrogen atom, 
v = 440 m/s
Substituting
Wavelength 
So the de broglie wavelength (in picometers) of a hydrogen atom traveling at 440 m/s is 902 pm
Answer:
Humans inherit 23 chromosomes from each parent
Explanation:
Answer:
A rheostat is a variable resistor which is used to control current. They are able to vary the resistance in a circuit without interruption. ... It uses only two connections, even when 3 terminals (as in a potentiometer) are present.
Explanation:
Answer:
A) 0.120
B) 1.6s
C) 0.625 Hz
Explanation:
Here, X = 0.120 m
x = 0.120 m after t = 0.800 s
A- Amplitude = max displacement from equillibrium position = 0.120 m
B- Period = 2 * 0.800 = 1.6 s
C- Frequency = 1/peroid = 1/1.6
f = 0.625 Hz
