1ly = 5.88 Trillion miles 4.2 x 5.8 Trillion = 24.696 Trillion m. 2. The fastest space probe ever designed has a speed of about 58,000 km/h. How long (in years) would it take it to reach the nearest star beyond our sun?

Time left 0:37:58 of on The force of gravitational attraction between two objects with masses m1 and m2, at a distance r apart, is given by Gm, m2 F = 12 of The dimensions of G (the universal constant of gravitation) is O a. M1L2T 3 O b. M1L3T2 O c. M'L3T2 O d. ML3T2

The speed of light is 2.998*10^8 m/s. How far does light travel in 7.0 μs ? Set the math up. But don't do any of it. Just leave your answer as a math expression. Also, be sure your answer includes all the correct unit symbols.

Number 6 & 7

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.

A light-year is a measure of the astronomical distance that light traverses in a vacuum in 1 year. (a) How many kilometers does light traverse in 1 ly? km (b) What is the speed of light c in terms of ly per year. ly/y (c) Express your answer from (b) in terms of feet per nanosecond. ft/ns

A space probe with a diameter of 2.50m is moving past Saturn's moon Enceladus. An observational platform on Enceladus measures the shortest length of the ellipsoidal probe to be 1.25m. How fast is the probe moving relative to the moon? a) .999c b) .995c c) .957c d) .883c e)  .866c

The speed of light is about 3 x 108 meters per second. The Millennium Falcon is traveling from Earth to Mars at the speed of light. The distance between the Earth and Mars fluctuates between 5.46 x 10¹0 meters and 4,01 x 10¹¹ meters. If the day the Millennium Falcon makes the "Mars Run," the distance is 2.25 x 10¹¹ meters, how long will it take them? Note: distance = rate time, and time = distance/rate Express your answer in scientific notation. Use for the multiplication. seconds Convert your answer to minutes. Include at least 3 decimal places in your answer, which can be expressed in standard notation. minutes Suppose the Millennium Falcon flies for 5 hours at the speed of light. How far will they travel? Express your answer in scientific notation. meters
