The velocity of light is 1.86 x 105 mi.s-1. A distance of one light year is that traveled by light in one year of 365 days. Express this distance in cm.
The question has to be written out first with the equation and then adding the numbers. ex. Lb x g/lb x kg/g = kg
We are given these conversion factors: 1 lb = 453.59g; 1 mile = 1.6093km

The Schwarzschild radius is the distance from an object at which the escape velocity is equal to the speed of light. A black hole is an object that is smaller than its Schwarzschild radius, so not even light itself can escape a black hole. The Schwarzschild radius r depends on the mass m of the black hole according to the equation 2Gm r = where G = 6.673 x 10-11 N.m²/ kg? is the gravitational constant and c = 2.998...

f) in vacuum, light travels at about 186,282 miles per second. One mile is about 161 kilometers (km). Astronomers prefer to use units of distance that are reasonable in describing how far objects are from Earth. For example, for distances in the solar system we use the astronomical unit (AU), which is equal to the average distance of Earth from the Sun; 1 AU is about 150 million km. For distances to stars and galaxies, astronomers use the light-year (1...

QUESTION 1 You have two slits of width a, a distance d apart. You shine light with a wavelength of 575 nm on the slits. On a screen 3.50 m from the slits, the 8th order interference dark fringe is 6.11 cm from the center of the screen. The 5th order diffraction dark fringe is 12.6 cm from the center of the screen. a) What is the distance between the slits d? b) What is the width of the slits...
