The velocity of light is 1.86 x 10^{5} 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 velocity of light is 1.86 x 105 mi.s-1. A distance of one light year is that...

How far is one light year in terms of kilometers. Which of the following equations is dimensionally consistenta a) x = vt + y at b) v = y at c) v = at + y at d) x2 = 2a(v-vo) e) None of these. Which one of...
#1. One lightyear is defined to be the distance light can travel in one year. (10 points) What is this distance in meters? How long does it take for light to get to the Moon? #2. Multiply 1.783 x 102 * 4.4 x 10-3, taking into account significant figures. (10 points) #3. What is the surface area of a sphere of diameter 2.4 x102 cm? (10 points) #4. What is larger 4000 L or 4 x 105 cm3 (and you...
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...
need help changignt the two second oder equations into four first order equations here R is the sphere's radius, p is the density of air, v is the velocity, and C is the called coefficient of drag (a property of the shape of the moving object, in this case a here). a) Starting from Newton's second law, F ma, show that the equations of motion for the position (x, y) of the cannonball are 2m where m is the mass...
