What is the mass of a proton in gigagrams? ) 1.67 10-39gg c ) 1.67 10-33 gg d) 1.67 10-30g

The mass of proton is

Explanation:

Proton is one of the sub-atomic particle which is present in the nucleus of the atom.

We know that:

Mass of proton =

To convert this into Giga grams, we use the conversion factor:

Converting the given value into Giga grams, we get:

Hence, the mass of proton is

weight of any object is given by

w = m*g

where m is mass of the object and g is the acceleration due to gravity.

for earth the value of g is 9.8 m/s^2 so

w=117.6 n m=12 g=?

117.6=12g => g=9.8 m/s^2

which is the force of gravity on earth.
