Consider six proposed properties of electromagnetic radiation: wave speeds of 3.00 × 108 km/s and 3.00 × 108 m/s, wavelengths of 479 nm and 0.115 nm, and frequencies of 2.21 × 1018 Hz and 7.06 × 1014 Hz. Sort these according to whether they apply only to the X ray band, only to the visible light band, to both bands, or to neither band.
The electric field between the plates of a parallel plate capacitor is horizontal, uniform, and has a magnitude of 3.5*10^4 N/C. What is the angle made by the thread with the vertical axis
An electron is released from rest in a uniform electric field and accelerates to the north at a rate of 199m/s2. What is the magnitude of the electric field?
An elevator is rising at a constant speed, subject only to the tension (T) and gravitational (W) forces exerted on it by the cable above and the Earth below. As it rises, which force (if either) has a greater magnitude, T or W? Explain.
how much work does the electric field do in moving a proton from a point with a potential of 145v to a point where it
The magnetic field in a certain region is 0.128 , and its direction is that of the axis in the figure. What is the magnetic flux across the surface ?
A loudspeaker of mass 19.0 is suspended a distance of = 2.00 below the ceiling by two cables that make equal angles with the ceiling. Each cable has a length of = 3.30. Illustrate what is the tension in each of the cables?
Find out the distance traveled (in meters) by the jet as the observer watches the nose of the jet cross from one side of the moon to the other.
A certain kind of glass has an index of refraction of1.650for blue light of wavelength430nm and an index of1.615for red light of wavelength690nm. compute the angle between the two beams inside the glass
A guy is spinning initially at a constant rate with his arms at his sides. He then puts his arms straight out. How much does his moment of inertia change when he sticks his arms out
a) How long does it take an airplane to take off if it needs to reach a speed on the ground of 350 km/h over a distance of 600 meters (assume the plane starts from rest)? b) What is the acceleration of the airplane over the 600 meters?
A 4.42 kg particle has the xy coordinates (-1.89 m, 0.146m), and a 3.34 kg particle has the xy coordinates (0.218m, -0.244 m). Both lie on a horizontal plane. At what(a)x and (b)ycoordinates must you place a 4.94 kg particle such that the center o..
