Xenon ions with a mass of 2.20 × 10-25 kilogram and charge +e are accelerated between the plates of an ion drive rocket engine to an exhaust velocity of 43,200 m/s.
(a) Obtain what the potential difference between the plates?
(b) If the potential difference is doubled, find what is the velocity of the engine exhaust?
Two slits are 0.156 mm apart. Amixture of red light (wavelength = 665 nm) and yellow-green light (wavelength = 565 nm) falls on the slits. A flatobservation screen is located 2.32 maway.
Horseshoe bats (genus Rhinolophus) emit sounds from their nostrils, then listen to the frequency of the sound reflected from their prey to determine the prey's speed. calculate the speed of the insect
Problem: A weather balloon is designed to expand to a maximum radius of 20m at its working altitude, where the air pressure is 0.030 atm and the temperature is 200 K. If the balloon is filled at atmospheric pressure of 300 K, what is the radius at li..
