How many kWh of energy does a 543 W toaster use in the morning if it is in operation for a total of 8 min? (answer in kWh) At a cost of 12 cents/kWh, estimate how much would this add to your monthly electric energy bill if you made toast four mornings per week. (Assume a month of 4 weeks.) (answer in cents/month)

U potential energy=k q1 q2r=V1 (voltage)*q2 ; Ekin = (1/2) m v2 1) How much energy must a single electron have as it leaves a 1.5 V potential assuming it started from rest? (an approximation of the batteries in lab) 2) How fast must that electron be moving as a result? 3) How much energy can that electron release before it comes to a stop, and why? 4) If current (I) is correlated to the speed of electron motion, then...

#13) multi-question. Provided useful equations.
Question 13 [8] A baseball player slides to 3rd base. A friction force (1) acts against his motion as indicated in the figure. He needs to slide a distance d of 2.5 m to be safe. (a) Use the work-energy theorem with non-conservative forces to write down an equation to find the actual distance the player slides. (b) If he starts sliding with an initial velocity of 5.0 m/s and the coefficient of kinetic friction...

C. 1. Can an electrically charged object produce an electric force on a neutral object? a. No, never. Coulomb's Law clearly says the force must be zero. b. Yes, but only if the neutral object is moving. C. Yes, if charge distribution in the neutral object is not uniform. This occurs often and naturally produces an attraction. d. Yes, if charge distribution in the neutral object is not...

1. What is the emf of a battery that increases the electric potential energy of 0.050 C of charge by 0.60 J as it moves from the negative to the positive terminal? 2 .A thermistor is a device whose resistance varies with temperature. At 20∘C a thermistor's resistance is 10.0 kΩ. When connected to a 1.2 V battery, the current through the thermistor increases by 20 μA as the temperature increases to 30∘C. What is the thermistor's resistance at this...
