Answer:
relay switch
Explanation:
relay switch is the answer
I believe its 17,000 blood cells in your body
The difference between the maximum and minimum values of voltage V across the 3 ohm resistor would be 9V.
To find the minimum and maximum values of V across the 3 ohm resistor, you will need to use Ohm’s Law, V=IR.
You already know the resistance is 3 ohms across the resistor; in order to calculate the maximum/minimum voltage across it, you will need to work out the maximum/minimum current of the series circuit.
Using Ohm’s Law to find the maximum and minimum current:
I = V/R
Where:
V = 12V (this is the emf, no volts are lost to the cell because the cell has a negligible internal resistance therefore all the 12V is transferred to the resistors in the circuit.)
The value for R however, changes due to the resistance in the variable resistor varying from 0 to 9 ohms.
The minimum value of R would be 3 ohms, where the resistance of the variable resistor is 0. Therefore total resistance = 3 + 0 = 3 ohms
Maximum value of R would be 12 ohms, where the resistance of the variable resistor is at a maximum of 9 ohms. Therefore total resistance = 3 + 9 = 12 ohms
The rest of the explanation is in the picture, hope it makes sense
To develop this problem we will proceed to convert all units previously given to the international system for which we have to:
PART A ) From the given values the minimum acceleration will be given for 120Lb and maximum acceleration when 170Lb is reached therefore:
Through the Newtonian relationship of the Force we have to:
PART B) For the maximum magnitude of the acceleration downward we have that:
Through the Newtonian relationship of the Force we have to:
