The starter motor in an old-fashioned internal combustion car will draw about 50 amps from the car battery when cranking, o. r. starting. You have trouble cranking your car and keep the starter motor turning for a full minute. How much work did the battery do on the starter motor

answer: 2×10^-2kg

explanation: density= mass per volume

vol=mass/density

converting to s.i units we have;

3÷1000kg = 0.003

1.5÷100m = 0.15

0.003/0.15 = 0.02kg

answergravity;

no. bullets are macro objects. wave nature is for light waves, extremely tiny particles. if a light particle was the size of your finger, the bullet would be the size of the universe. so basically, that huge difference in size makes the wave nature of matter insignificant.

ingenuity says that the answer is 2.7 m.
