3energy storage consider the capacitor as a device for storing energy. the practical limitation on the potential difference between the plates of a capacitor is the "dielectric strength" of the dielectric material between the plates. this is the maximum field strength that can exist without causing a spark. it is typically on the order of 107 v/m for a good liquid dielectric with k 2.3 and ρ ~: 1 g/cm3 (a) neglecting the weight of the electrodes and case, what is the energy density of the capacitor in j/kg? le., how many joules of energy can be stored per kilogram of dielectric? physics 222 winter 2018 january 21, 2018 (b) the energy density of gasoline is about 46 mj/kg, and gasoline has a density of about 0.75 g/cm3. assume a gas tank holds about 12 gallons when full. what mass of dielectric would be required to provide the same energy as a tank of gasoline?

Two thin 80.0- cm rods are oriented at right angles to each other. each rod has one end at the origin of the coordinates, and one of them extends along the x- axis while the other extends along the yaxis. the rod along the x- axis carries a charge of - 15.0 μ c distributed uniformly along its length, and the other rod carries 15.0 μ c uniformly over its length. find the magnitude and direction of the net electrical force that these two rods exert on an electron located at the point (40.0 cm, 40.0 cm).

Arunner is jogging at a steady 3.6 km/hr. when the runner is 2.9 km from the finish line, a bird begins flying from the runner to the finish line at 14.4 km/hr (4 times as fast as the runner). when the bird reaches the finish line, it turns around and flies back to the runner. even though the bird is a dodo, we will assume that it occupies only one point in space, i.e., a zero-length bird. how far does the bird travel? (b) after this first encounter, the bird then turns around and flies from the runner back to the finish line, turns around again and flies back to the runner. the bird repeats the back and forth trips until the runner reaches the finish line. how far does the bird travel from the beginning? (i.e. include the distance traveled to the first encounter)
