Neptune has a mass 17.20 times larger than that of Earth and a radius 3.88 times larger. A person weighing 140 lb on the Earth would weigh how much on Neptune.
A proton accelerates from rest in a uniform electric field of 675 N/C. At some later time, its speed is 1.35 106 m/s. (a) Find the magnitude of the acceleration of the proton.
A solid has a volume of 8cm3. When weighed on a spring scale calibrated in grams, the scale indicates 20g. What does the scale indicate if the object is weighed as immersed in a liquid of density 2g/cm3.
What is the thinnest soap film (excluding the case of zero thickness) that appears black when viewed by reflected light with a wavelength of 480 {rm nm}? The index of refraction of the film is 1.33, and there is air on both sides of the film.
A car takes a sharp turn on a road. Which of the following provides the centripetal force on the car? The weight of the car, frictional force, tangential acceleration, or gravitational force?
Two parallel rods are each 0.50 m in length. They are attached at their centers to either end of the spring (spring constant = 150 N/m) that is initially neither stretched nor compressed.
A mass rests on top of the piston. The initial temperature of the system is 305 K and the pressure of the gas is held constant at 137 kPa. The temperature is now increased until the height of the piston rises from 23.4 cm to 27.0 cm. What is the f..
