A hydrogen atom in its ground state is excited to the n = 5 level. It then makes a transition directly to the n = 2 level before returning to the ground state. Note: There are TWO transitions here. First from n = 5 to n = 2, and then from n = 2 to n = 1. (You will discover that only ONE of those transitions result in a visible wavelength, the other is from the Lyman series or far UV part of the spectrum.)
a) What are the wavelengths of the emitted photons?
b) Would any of the emitted wavelengths be in the visible region?
Saturn's moon Titan is the largest moon in the solar system. Its mostly-nitrogen atmosphere exerts a pressure of 1.60×105 Pa at the moon's surface.
In the Biomedical and Physical Sciences building at MSU there are 132 steps from the ground floor to the sixth floor. Each step is 16.6 cm tall. It takes 6 minutes and 53 seconds for a person with a mass of 70.8 kg to walk all the way up.
A steel wire in a piano has a length of 0.60- m and a mass of 4.5 x10-3 kg. To what tension must this wire be stretched in order that the fundamental vibration correspond to middle C (fC = 261.6 Hz on the chromatic musical scale).
If the car was in neutral and its brakes were off, so that the collision is approximately elastic, find out the final speed of the truck.
A rotating wheel requires 3.08-s to rotate through 37.0 revolutions. What is the constant angular acceleration of the wheel
What is Fx of the magnitude of the skiers velocity.
A note played on a piano is 4719 Hz. If the speed of sound is 347 m/s, what is the wavelength of the note?
A flight attendant pulls her 70.0N flight bag a distance of 244 m along a level airport floor at a constant speed. The force she exerts is 36N at an angle of 52° above the horizontal. Find the work she does on the flight bag.
A plate of glass with parallel faces having a refractive index of 1.57 is resting on the surface of water in tank. A ray of light coming from above in air makes an angle of incidence 34.5 degrees with normal to the top surface of the glass.
the second person is initially at rest. Illustrate what are the velocities of the two people after the snowball is exchanged? Disregard the friction between the skates and the ice.
What is the relationship between the length of a wire and magnetic force, Is the relationship between current and magnetic force linear
A block of mass m = 2.10 kg is pushed a distance d = 4.20 m along a frictionless horizontal table by a constant applied force of magnitude F = 16.0 N, Determine the work done on the block by the applied force
