The starter motor of a car engine draws a current of 140A from the battery. The copper wire to the motor runs for 0.90s until th
nasty-shy [4]
"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)

An astronaut weighing 248 lbs on Earth is on a mission to the Moon and Mars. (a) What would he weigh in newtons when he is on th
lesantik [10]

Answer:

W_m=183.495N

Explanation:

From the question we are told that:

Weight W=248Ibs

Mass of Weight  m= 248*0.453

                          m=112.344kg

Generally the acceleration due to gravity on the Moon is one-sixth that on Earth.

Therefore

The equation for Weight on Moon is given as

 W_m=m*g/6

 W_m=122.344*\frac{9.8}{6}

 W_m=183.495N
