Will the current increase or decrease if you increase voltage?

It will increase

Explanation:

All other things being equal, an increase in voltage will produce a corresponding increase in current, or flow of electrons. Voltage and current are related in a positive way, as one increases the other increases and vice versa.

correct it is c.) b b

force is mass*acceleration.

we have a very small mass: 11.4*0.001 kg

if we want 0.035n of force, we need an acceleration:

0.035 = 11.4*0.001*a

a = 0.035/(11.4*0.001) m/s^2
