Please answer fast its important

Answer 1

Answer:

1) a) Q to P

2) d) none of the above.

3)b) 360 ms-1

4)b) m×g

Explanation:

1) Because electrons always flow form + terminal to - terminal.

2) answer is 245.166N

3) s=d÷t

4)The weight of an object is defined as the force of gravity on the object and may be calculated as the mass times the acceleration of gravity, w = mg. Since the weight is a force, its SI unit is the newton.
