I wasn't sure because all the questions I had done before this had very small resistance (like 6), and I wasn't sure what an actual appliance might have in terms of resistance. Thanks for the confirmation!
Homework Statement
A typical electric blanket consumes 50 W of power when operating. What is the overall resistance of the blanket if it is designed to be plugged into a standard powerpoint?
Power = 50 watts
Voltage = 240 v (standard powerpoint)
Homework Equations
I (current) = Voltage/...
Homework Statement
Having trouble with the concept here and have gotten stuck!
A man is pushing a mobile machine down a corridor at a steady speed of 1.2 m/s. The machine’s mass is 55 kg. Another person who has been walking in front of the machine has suddenly stopped. If the man is able to...
The pressure would have to increase, right? If it's going faster, then there's Acceleration so according to the formula: Force = Mass X Acceleration, Acceleration is increasing and that would mean that Force is increasing, which would result in Pressure going up via the formula Pressure = Force/...
A force, right? So that means that there's more force acting on the same area and that would increase the pressure since Pressure = Force/ Area?
Would that be correct? I think I'm seeing the connection now.
Homework Statement
Question:
For a fluid flowing within a horizontal tube, if the diameter of the tube narrows, will the fluid's flow rate increase, resulting in increased pressure in the narrowing and explain your reasoning.

Volume flow rate = volume/time
Volume = Area x...
