A singly ionized 24Mg ion (mass 3.983 10-26 kg) is accelerated through a 2.0 kV potential difference and deflected in a magnetic field of 500 G in a mass spectrometer.
(a) Find the radius of curvature of the orbit for the ion.
(b) What is the difference in radius for 26Mg and 24Mg ions? (Assume that their mass ratio is 26/24.)
An airplane must reach a speed of 377mi/h in order to take off. If the runway is 403 m long, what is the minimum value of the acceleration that will allow the airplane to take off successfully.
a 142 kg crate is placed on an inclined ramp. When the angle the ramp makes with the horizantal is increased to ALPHA, If the coefficient of static friction between the crate and the ramp is 0.65, what is the angle alpha when the crate just begins t..
A 1500 car travelling at 26 suddenly runs out of gas while approaching the valley that looks like an inverted hump. 12m at the left where the care runs out of gas and 19 m at the right were it is headed. What will be the car's speed as it coasts into..
Two sound sources radiating in phase at a frequency of 485 Hz interfere such that maxima are heard at angles of 0 and 22° from a line perpendicular to that joining the two sources. Find out the separation between the two sources.
