In a hot star, as of the high temperature, an atom can absorb sufficient energy to remove several electrons from the atom. Consider such a multiply ionized atom with a single remaining electron. The ion produces a series of spectral lines as described by the Bohr model. The series corresponds to electronic transitions that terminate in the same final state. The shortest and longest wavelengths of the series are 22.8 nm and 63.3 nm, respectively.
(a) Determine what is the ion?
(b) Compute the wavelengths of the next three spectral lines nearest to the line of longest wavelength.
Starting from rest, a boat increases its speed to4.12 m/s with constant acceleration. What is the boat's average speed? If it takes the boat 4.62 s to reach this speed, how far has it traveled?
Two spaceships approach Earth with equal speeds, as measured by an observer on Earth, but from opposite directions. A meterstick on one spaceship is measured to be 60 cm long by an occupant of the other spaceship. What is the speed of each spaceship,..
An elastic conducting material is stretched into a circularloop of 11.0 cm radius. It is placedwith its plane perpendicular to a uniform 0.600 T magnetic field. What emf is induced in the loop at that instant
The car encounters a loop of radius R = 18 m at ground level. As you will learn in the course of this problem, the initial height 54.00 m is great enough so that the car never loses contact with the track.
A 2.97-kg projectile is fired with an initial speed of 133 m/s at an angle of 28° with the horizontal. At the top of its trajectory, the projectile explodes into two fragments of masses 0.97 kg and 2 kg. At 3.87 s after the explosion, the 2-kg fragme..
The CGS unit for measuring the viscosity of a liquid is the poise (P): 1 P = 1 g/(s·cm). Express this viscosity in poise
