An object is located 8.00 cm from a converging lens that has a focal length of 10.0 cm. The height of the object is 0.41 cm. What is the height hi of the image?
A particle moves along the x-axis. Its position varies with time according to the expression x(t) = -4t + 2t2, where x is in meters and t is in seconds. a) Determine the displacement of the particle in the two time intervals t = 0 to t = 1 s and t..
Suppose the highway is icy and the coefficient of friction between the tires and pavement is only one-third what you found in part A. Illustrate what should be the maximum speed of the car so it can round the curve safely?
An insulated Thermos contains 150cm3 of hot coffee at 83°C. You put a 12g ice cube at its melting point to cool the coffee. By how many degrees has your coffee cooled once the ice has melted and equilibrium is reached? Treat the coffee as although..
A 1000-N uniform beam is attached to a vertical wall at one end and is supported by a cable at the other end. A 1960-N crate hangs from the far end of the beam.
A certain medical machine emits x-rays with a minimum wavelength of 0.025 nm. One day, the machine has an electrical problem and the voltage applied to the x-ray tube decreases to 80 percent of its normal value. Now what is the minimum x-ray wavel..
Consider two inertial reference frames. while an observer in each frame measures the following quantities, which measurement made by two observers must yield the same results.
On a summer day, the air conditioning breaks down and the air in your classroom becomes very warm and muggy with a vapour pressure of 20 hPa and a temperature of 25o C.
What is the gas pressure? Give your answer in atm. The gas then undergoes an isothermal compression until the pressure is 3.1atm, What is the final temperature of the gas
