In a single slit diffraction experiment, the screen is placed 2.40m away from the slit. Light with a wavelength of 680nm forms a pattern on the screen and the fourteenth dark fringe form 77.0cm above center of the pattern. What is the width of the slit?
A 2.0 mm-diameter glass bead is positively charged. The potential difference between a point 2.2 mm from the bead
Estimate the maximum centrifugal and coriolis forces that you would experience on a ferris wheel in Melbourne, FL. How does this compare with gravity? (Please use the earth's surface as the reference frame).
During open-heart surgery, a small current of 25 μA may cause ventricular fibrillation. Suppose the heart resistance to be 250 Ω, find the voltage level posing a hazard to the patient's health
An ocean liner leaves New York City and travels 12.0° north of east for 111 km. How far east and how far north has it gone? In other words, what are magnitudes of the components of the ship's displacement vector in the directions.
two stationary positive point charges charge 1 of magnitude 3.10nc and charge 2 of magnitude 1.75nc are separated
Suppose you are planning a trip in which a spacecraft is to travel at a constant velocity for exactly eight months, as measured by a clock on board the spacecraft, and then return home at the same speed.
What is the potential difference between the center of the disk and the edge? (Use the following as necessary: R, B, ?.) [Hint: Think of the disk as a large number of thin wedge-shaped rods. The center of such a rod is at rest, and the outer edge mov..
A brass ball is shot vertically upward from the surface of an atmosphere-free planet with an initial speed of 20.0 m/s. One second later, How high does the ball rise
A mass spectrometer is used to examine the isotopes of uranium. Ions in the beam emerge from the velocity selector at a speed of 3.02 105 m/s and enter a uniform magnetic field of 0.625 T directed perpendicularly to the velocity of the ions.
A mass is oscillating on a spring with a period of 4.60 s. At t=0 s the mass has zero speed and is at x=8.30cm. What is the value of t the first time after t=0s that the mass is at x=4.15?
a wheel is spinning freely on its axis with an angular velocity w of 2 rad/s. What is its renitic energy if the angular velocity is increased to 10 rad/s
consider an electron with an initial speed v0 = 32 Mm/s (1 Mm = 1 megameter = 1000 km = 1E6 m), What distance d (in m) will the electron travel before it stops
