How do you calculate the electrical energy from a power versus time graph?
The graph shows the electrical energy consumption of a typical household.... How do you work this?
1. Power and Work: What units are used to measure power? How would you calculate work from a graph of power vs. time? 2. Energy and Capacitance: How much energy can a capacitor C store at a given voltage? Call this quantity E. How much energy (in terms of E) can the capacitor store if the voltage is doubled? 3. Assume you have just used the energy stored in a capacitor to raise up a mass on a string using...
Choose a function to represent the acceleration vs. time graph. How can you calculate the values of the constants of this function from the function representing the position versus time graph? Check how well this works. You can also estimate the values of the constants from the graph. What kinematics quantities do these constants represent? Record the corresponding kinematic quantities and the values of the corresponding errors. From either the position vs. time, velocity vs. time, or acceleration vs. time...
Problem 7. Below you are supplied a position versus time graph. Draw velocity versus time and acceleration versus time graphs consistent with this position versus time graph. Assume that this is one dimensional motion along the x axis, that you are standing on the origin (x = 0) with positive x off to your right and negative x off to your left. Describe the motion of the object in everyday terms without using the words velocity, acceleration, slope, positive or...

On a graph of wave displacement versus time OR space, the points in the domain where the wave crosses the horizontal axis, meaning "zero displacement" are called A On a graph of wave displacement versus space OR time the points in the domain that correspond to a maximum value (positive displacement) or minimum value (negative displacement) of the oscillating value are called A The magnitude of the greatest value of the oscillating quantity or the greatest value of the displacement...
Q.8: An electrical power plant operates on the basis of thermal energy generated in a pressurized water reactor. The electrical power output of the plant is 1 GW, and its efficiency is 30% (a) Find the total power generated by the reactor. (b) How much power is discharged to the environment as waste heat? (c) Calculate the rate of fission events in the reactor core (Let the energy produced per fission event be 200MeV) (d) Calculate the mass of 235U...
