Hello! Force = mass * acceleration. We can go ahead and eliminate A and B, because those answers are too small. We can multiply 4.5 (mass) * 9 (acceleration) to find the amount of force needed. 4.5 * 9 is 40.5.The amount of force needed is 40.5 N. The answer is C: 40.5 N.

Answer:
d. 12 A
Explanation:
The current and the voltage in a resistor are related by Ohm's Law:
where
V is the potential difference across the resistor
I is the current in the resistor
R is the resistance
In this problem, we have
is the potential difference across the resistor
is the resistance
Solving the equation for I, we find the current:
