<u>Answer:</u>
Mass of base ball
<u>Explanation:</u>
Circumference of baseball = 2πr = 23 cm
So radius of baseball = 3.66 cm = m
Mass per unit volume of baseball = Mass per unit volume of neutron or proton.
Mass of proton = kg
Diameter of proton = m
Radius of proton = m
Volume of ball =
Now substituting all values in Mass per unit volume of baseball = Mass per unit volume of neutron or proton.
So mass of base ball
