Electric cars reduce greenhouse gas emissions, but electric cars still are responsible for some greenhouse gas emissions. A. Calculate the grams of CO2 per km travelled for an internal combustion engine car if the car gets 32 miles per gallon (13.5 km per L). The carbon intensity of refined gasoline is 96.86 g CO2/MJ. The energy density of gasoline is...

1. An electron (q = -1.6x10-19 C, m=9.11x10-31 kg) is placed in an electric field of magnitude 3.52x104N/C which points in the positive z direction. Calculate the magnitude and direction of the acceleration of the electron. 2. An electron is initially moving in the +z direction, with a speed v=2.54x105 m/s at z=0. In the region between z=+1.50 cm and...

You are working on a project to make a more efficient engine. Your team is investigating the possibility of making electrically controlled valves that open and close the intake and exhaust openings for an internal combustion engine. This device is mounted on an axis so that it can spin freely to close the valve. Your assignment is to determine the...

1. The figure to the right shows a particle undergoing simple harmonic motion described by x(t)= A cos(at +o). Notice that x(0) = A/2. What is the phase constant? 2. The figure to the right shows a snapshot of circular waves emitted by two in- phase sources. The point marked by the dot (directly in between two wave fronts emitted from...

Question C. I don' know where
to start. I've looked at worked solutions to similar problems but I
can't explain why each step was taken.
3. (a) Write down the integral form of Faraday's law (Maxwell's third equation) and briefly explain what is meant by each of the terms in the equation. (3 marks) (b) With reference to Faraday's law,...

You may recognize the figure below from an earlier homework. It, however, represents a very different physical situation: this is now a very long (infinite for our purposes) conducting wire in the form of a cylindrical shell. The inner radius of the shell a=3.5 mm and outer radius b=5.2 mm. The electric current I=10.5 A runs along this wire and...
