Answer:
Put a 10.0-ohm resistor in the circuit. Measure the current in the circuit. Replace the 10.0-ohm resistor with a 20.0-ohm resistor. Measure the new current. Continue replacing the resistor with a different resistor of known resistance. Measure the current for each resistor. Record all data.
Explanation:
The only design that has resistance varying with everything else remaining the same is the first design. That would be what you'd want to do if you're exploring the effect of resistance on current.
Answer:
Explanation:
By an adequate application of the Principle of Energy Conservation, the escalator need energy to elevate from to the bottom to the top. Hence:
An expression for power needed is found by deriving the equation with respect to time:
The minimum power is found by substituting known inputs:
Answer:
Detailed step wise solution is given below:
By increasing magnification you decrease the field of view.
The answer is A.
