Here as we can see that weight on the right side of ruler given as D is applying torque about the fulcrum this is counter balanced by weight on left side given as A
now by torque balance we can say
now we will have
now here as per given setup we can see that
so here we will have
so the weight required to hold D will be more and correct answer will be
<em>The setup increases the amount of force required to lift the block and, therefore, decreases your mechanical advantage.</em>
Answer:
R = 0.1 ohms
Explanation:
It is given that,
Voltage of the battery, V = 12.5 V
Current flowing in the car's starter, I = 125 A
We need to find the effective resistance of a car's starter. It can be calculated using Ohm's law. Let R is the resistance.
So, the resistance of the car's starter is 0.1 ohms.
