Light from an argon laser strikes a diffraction grating that has 5 310 grooves per centimeter. The central and first order principal maxima are separated by 0.488 m on a wall 1.72 m from the grating. Determine the wavelength of the laser light.
Suppose a tank contains 770 m3 of neon (Ne) at an absolute pressure of 1.01×105 Pa. The temperature is changed from 293.2 to 295.6 K. What is the increase in the internal energy of the neon?
A simple camera telephoto lens consists of two lenses. The objective lens has a focal length f1 = 38.8 cm. Precisely 35.7 cm behind this lens is a concave lens with the focal length f2 = -10.3 cm. The object to be photographed is 3.97 m in front o..
For a particular collision you detect the emitted products and find 15 protons, 2 antiprotons, 6 positrons, and 25 neutral particles. How many electrons are also emitted?
Suppose a 63.00 kg boy and a 50.00 kg girl use a mass less rope in a tug-of-war on an icy, resistance-free surface. If the acceleration of the girl toward the boy is 3.00 m/s2, find out the magnitude of the acceleration of the boy toward girl.
a hair dryer operates at 1800 watts along with a 240 watt power resistor connected in series. Utilizing a 120 volt source, determine the individual resistance Ri and the voltage drop Vi across each compenent in the circuit
Kinetic energy KE has dimensions kg · m^2/s^2. It can be written in terms of the momentum p and mass m as KE=p^2/2m. (a) Determine the proper units for momentum using dimensional analysis. (Use the following as necessary: kg, m, and s.)
