How many coulombs of positive charge are there in 3.60 kg of plutonium, given its atomic mass is 244 and that each plutonium atom has 94 protons?

1 mole of plutonium = 244 gm

3.6 kg of plutonium = 3.6 × 1000 = 3600 gm

Number of moles = 3600 ÷ 244 = 14.754 moles

One moles of plutonium contains protons =

Total number of protons in 14.754 moles =

Total number of protons in 14.754 moles =

Total Positive charge =

Total positive charge = C

a. are

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.
