I was able to understand the attached problem and have the answer now for mu. So the equation I have is v=150e-6.0788 x My question, then, is how do we find the TIME to slow the sled to 15 mi/hr ? The answer is supposed to be 35.533 seconds, but I don't know how to get that. Thanks!
In general relativity, gravity changes time. Gravitational potential = - G M / R. Time change r = At/t = A/c². A satellite (e.g., GPS) orbits 21 km above Earth surface, and gravity at the satellites are a little different from Earth surface. The distance error is Ad = c At. Ad is km in one day Please do not copy and paste. Thank you!
Can you please help w/ the question in the pic? This is the data I have so far: 1. Determine the mass M of the massive object at the center of the Milky Way galaxy. Take the distance of one light year to be 9.461x10^15: answer= 4.26*10^37 2.Express your answer in solar masses instead of kilograms, where one solar mass is equal to the mass of the sun, which is 1.99*10^30: answer=2.14*10^7 TIA
The remaining lifetime of the Sun in seconds is 1.5 x 10¹7 sec. Convert this value into years. 0000000000000000 PLS HELP!
Tim and Rick both can run at speed , and walk at speed vw, with ur > Uw. They set off together on a journey of distance D. Rick walks half of the distance and runs the other half. Tim walks half of the time and runs the other half.
The speed of a gravitational wave is reported to be the same as the speed of light, which is 3.0 x 108 m/sec. How many times in 1.0 sec would a traveler moving at the speed of light circumnavigate the Earth at the poles where the diameter is roughly 7.8998 x10³ miles? (recall the circumference of a circle is 2πr). O 750 01 O 7.5 O 0.75 O 10.0
QUESTION 2 A parsec is a unit of length equal to about 3.10X1013 km. How long will it take light, moving at 3.00X108 m/s to travel 1.00 pars (3.154X10 seconds = 1 yr) O a.I don't know, but I made the Kessel run in less than 12 parsecs b.3.27 yrs O c. 10.3 yrs O d.9.68 yrs O e.525600 min
How do you find the distance traveled between 6s and 14s? I got 24m, but I'm unsure.
A light year (LY) is the distance that light travels in one year. 1 LY = 9.46x1015 m. Suppose we have detected a planet that orbits a star that is 104 light years away. How many millions of years would it take us to get there if we used a modern rocket with a maximum speed of 20.0 km/s (about 45,000 mph)? Assume 3 sig figs.
