One kilogram of water is heated from an initial temperature of 283K to a final temperature of 372K. Calculate the change in entropy. Assume the specific heat of water to be 4186 J/kgK. Hint: the amount of heat gained is a function of the temperature.
Light strikes a metal surface, causing photoelectric emission. The stopping potential for the ejected electrons is 3.4 V, What is the wavelength of the incident light
Let h = 25.5 m and vi = 13.6 m/s. Find the speed of the ball just before it hits the ground. vf = 26.167919 m/s Find the ball's mechanical energy at the release point. KEi + PEi = _______J Find the ball's mechanical energy just before it hits the gro..
A barbell spins around a pivot at its center at A. The barbell consists of two small balls, each with mass 450 grams (0.45 kg), at the ends of a very low mass rod of length d = 35 cm, calculate the total kinetic energy of the barbell
Gas is confined in a tank at a pressure of 11.7 atm and a temperature of 30.0°C. If two-thirds of the gas is withdrawn and the temperature is raised to 77.0°C, what is the pressure of the gas remaining in the tank? atm
A stone is dropped into a river from a bridge 43.90 m above the water. Another stone is thrown vertically down 1.00 after the first is dropped. The stones strike the water at the same time.
Find the x- and y-coordinates of the center of gravity of a 4.00 ft by 8.00 ft uniform sheet of plywood with the upper right quadrant removed as shown in the figure below. The dimensions of the cutout are a = 4.10 ft and b = 2.10 ft. HINTS: Think ..
