A light-year (ly) is the distance light travels in one year (at speed of 2.998 ×× 108 m/sm/s ). An astronomical unit (AU) is the average distance from the Sun to Earth, 1.50 ×× 108 kmkm.1 yearyear = 3.156 ×× 107 ss. a. How many meters are there in 6.50 lyly ? Express your answer using three significant figures. b. How many AUAU are there in 6.50 lyly light-year? Express your answer using three significant figures.
true or false. I- The speed of light in vacuum is a universal constant, whose value (without uncertainty, as it is defined as a standard) is c=299792458 m.s -1..The value of c in scientific notation is 2.99792458 x108 m.s-1. II- The value of c (velocity of light in vacuum) written to 3 significant figures is 3.00 x 108 .m.s-1. III- The value of the density of an object obtained was ρ±uρ=(7.768581114 ± 0.012540242) g.cm -3. The value obtained for the density and its respective uncertainty is incorrect, as it makes no sense to report the uncertainty with so many decimal places. IV- To convert g/cm 3 to kg/m 3 just multiply by 10 3.
a. Light Post f h d. A robot holds an upright measuring stick that is 8.00 cm in length and a distance of 20.0 cm from its face. The robot is a distance of 15.0 m from the projection of the top of the lamp post onto the ground. The robot's eye level height is 1.80 m. Use this information to determine the height of the lamp post, filling in the table below with the proper quantities measure in meters. 1= stick length x = stick g = eye level height d = object distance f= object height from h = full object height A = angle from eye level to top of eye level object distance What is the full height in feet?
An astronomical unit (AU) is equal to the average distance from Earth to the Sun, about 92.9 × 106 mi. A parsec (pc) is the distance at which a length of 1 AU would subtend an angle of exactly 1 second of arc (the figure). A light-year (ly) is the distance that light, traveling through a vacuum with a speed of 186000 mi/s, would cover in 1.0 year. Express the Earth–Sun distance in (a) parsecs and (b) light-years.
A tape measure that can be read to the nearest eighth of an inch gives your height as 62 3/8 inches. A new laser device at the doctor’s office that gives readings to the nearest 0.05 inch gives your height as 62.35 inches. Your true height is 62.50 inches. a. Which measuring device is more accurate? (WORK: Compare the absolute errors for the measuring devices.) Answer: Tape OR Laser is more accurate. (Circle your choice above.) b. Which measuring device is more precise? (WORK: Compare the increments of measure for the measuring devices.) Answer: Tape OR Laser is more precise. (Circle your choice above.)
All the stars of the Big Dipper (part of the constellation Ursa Major) may appear to be the same distance from the earth, but in fact they are very far from each other. the figure shows the distances from the earth to each of these stars. The distances are given in light-years (ly), the distance that light travels in one year. One light-year equals 9.461 × 1015 m..

Current Attempt in Progress In astronomy, distances are often expressed in light-years. One light-year is the distance traveled by light in one year. If the distance to a star is 4.2 light-years, what is this distance in meters? (There are 365.25 days in one year.) Number i Units
According to Timothy Treadwell in 2001 "Now, the bears I live with average, the males are on average twelve hundred pounds. They're the largest bears in the world and they've been clocked at 41 [mph] and they've run a hundred meter dash in 5.85 seconds which human on stimulants doesn't even approach. a. Compute the speed of a grizzly bear using Mr. Treadwell's hundred-meter statement. b. Compute the momentum of a grizzly bear using the speed you calculated in part a. and the average mass stated by Mr. Treadwell. c. How fast would a 250 lb man have to run to have the same momentum you calculated in part b? d. How fast would a 4000 lb car have to drive to have the same momentum you calculated in part b?
