the answer is a because they start on the north side
Answer:
q = 13 C
Explanation:
Given that,
Electric current, I = 20 A
The starter motor runs for 0.65 s before the car engine starts up.
We need to find how much of electric charge passes through the starter motor. Let it is q.
Electric current = electric charge/time

So, 13 C of electric charge passes through the starter motor.
There are 8 hydrogen atoms
Answer:
388.5J
Explanation:
Given parameters:
Weight = 70N
Height = 5.55m
Unknown:
Gravitational potential energy at the top of the ladder = ?
Solution:
The gravitational potential energy is the energy due to the position of the body.
Gravitational potential energy = Weight x height
So;
Gravitational potential energy = 70 x 5.55 = 388.5J
Hence, 0.60+2.25eV is the solution to this problem
