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
An apple falling to the ground is not an example of centripetal acceleration.
Answer:
1. Hydrogen
Atomic # = 1
Atomic Mass = 1.00794 ( If you round it it's 1.008 )
# of protons = 1
# of neutrons = none
# of electrons = 1
<span>It stores energy and delivers it in a short burst.
The whirring sound is produced by the charging of the capacitor. A capacitor is an electrical component which is capable of storing charge. When the capacitor stores charge, it is storing energy. After doing so, the capacitor releases the electrical energy that it had stored as light energy, which is seen as the flash of the camera. It must do so in a burst, because the intensity of the flash is very high and would require a high amount of energy to maintain.
