Because upward buoyant force is slightly higher than gravitation force for this particular object
Answer:
770m/s
Explanation:
caculation using one of the newton law of motion
"1 Ampere" (A) means "1 coulomb of charge per second"
140 A means 140 coulombs per second
(140 coulomb/sec) x (0.9 sec) = 126 coulombs of charge.
Go a little farther:
Electrons are the things that move through wire carrying charge.
6.25 x 10¹⁸ electrons carry 1 coulomb of charge.
126 coulombs = 787,500,000,000,000,000,000 electrons (rounded)
