A parallel-plate capacitor has square plates that are 7.80 cm on each side and 3.60 mm apart. The space between the plates is completely filled with two square slabs of dielectric, each 7.80 cm on a side and 1.80 mm thick. One slab is Pyrex glass and the other slab is polystyrene. If the potential difference between the plates is 92.0 V, find how much electrical energy (in nJ) can be stored in this capacitor.

A1000-kg weather rocket is launched straight up. the rocket motor provides a constant acceleration for 16-s, then the motor stops. the rocket altitude 20-s after launch is 510-m. you can ignore any effects of air resistance. a. what was the rocket’s acceleration during the first 16-s? b. what is the rocket’s speed as it passes through a cloud 5100-m above the ground?

An engineer designs a roller coaster so that a car travels horizontally for 152 ft, then climbs 137 ft at an angle of 34.0° above the horizontal. it then moves 137 ft at an angle of 48.0° below the horizontal. if we take the initial horizontal motion of the car to be along the +x-axis, what is the car's displacement? (give the magnitude of your answer, in ft, to at least four significant figures and give the direction of your answer in degrees counterclockwise from the +x-axis.)
