In a Young's double-slit experiment the separation distance y between the second-order bright fringe and the central bright fringe on a flat screen is 0.0175 m, when the light has a wavelength of 425 nm. Assume that the angles are small enough so that sin is approximately equal to tan. Find the separation y when the light has a wavelength of 567 nm.
An insect 4.00mm tall is placed 20.0cm to the left of a thin planoconvex lens. Calculate the location of the image this lens forms of the insect
A system performs 352 J of work on its surroundings while losing 133 J of internal energy. Determine the heat transferred to the system during this process
what is the buoyant force on a beachball of diameter 20.0 cm that is HALF submerged in a fresh water pool
q1. assume that you are walking perpendicularly with a velocity of 0.90 ms toward a stationary plane mirror. what is
Evangelista Torricelli was the first person to realize that we live at the bottom of an ocean of air. He correctly surmised that the pressure of our atmosphere is attributable to the weight of the air.
At our distance from the Sun, the intensity of solar radiation is 1370 W/m2. The temperature of the Earth is affected by the greenhouse effect of the atmosphere.
One way to monitor global warming is to measure the average tempo f the ocean . Researches are doin ghtis by measuring the time ittakes sound pilses to travel underwater over large distance.
Someone decides to produce electrical power by turning a coil with 10^5 circular loops in the Earth's magnetic field. determine the average power obtained from this device
A modern house is wired for 120.0 V, and the current is limited by circuit breakers to a maximum of 290.0 A. (For the purpose of this problem, treat these as DC quantities.) Calculate the minimum total resistance the circuitry in the house can hav..
A golf ball is dropped from rest from a height of 9.50 m. It hits the pavement, then bounces back up, rising just 5.50 m before falling back down again. A boy then catches the ball when it is 1.30 m above the pavement. Ignoring air resistance, cal..
A certain laboratory experiment requires an aluminum wire of length of 36.0 m and a resistance of 2.30 ? at 20.0°C. What diameter wire must be used? (The resistivity of aluminum at 20.0°C is 2.82 10-8 ? · m.)
