Abaseball weighs 220 g. top speed for a professional pitcher is about 100 mph when he throws a fast ball. find the de broglie wavelength (in nm) associated with a baseball that is moving with a velocity of 69 mph.

The de Broglie wavelength associated with a baseball is.

Explanation:

De-Broglie wavelength is calculated by using the formula:

     .....(1)

where,

= wavelength of particle

h = Planck's constant =

m = mass of particle

v = velocity of particle

We have :

m = 220 g =0.220 kg

velocity of the baseball , v= 69 mile/h

1 mile = 1609.34 m , 1 hour = 3600 s

v =

()

The de Broglie wavelength associated with a baseball is.

b.

the accuracy of the data.

c is having 4 valence electrons and is bonded to three hydrogens and one sulphur atom, therefore, the number of bond pair is equal to four. as all the valence electrons are used in forming the bonds so, there is no lone pair left on carbon.

s is having 6 valence electrons and is bonded to one other sulfur atom and one carbon atom, therefore, the number of bond pair is equal to 2. as only two valence electrons are used in forming the bonds so, four electrons are left. therefore, two lone pairs are present on s.
