A Global Positioning System (GPS) receiver is a device that lets you figure out where you are by receiving timed radio signals from satellites. It works by measuring the travel time for the signals, which is related to the distance between you and the satellite. By finding the ranges to several different satellites in this way, it can pin down your location in three dimensions to within a few meters. How accurate does the measurement of the time delay have to be in units of nanoseconds to determine your position to 10 m accuracy? 1 s = 10^9 ns

In 1980, the Voyager spacecraft sent back beautiful photographs of Saturn via radio transmission. If the distance between Earth and Saturn was 1.277 x 1012 m, how much time (in minutes) was required for the transmission?
Consider the equation s = s0 + v0t + a0t2/2 + j0t3/6 + S0t4/24 + c0t5/120 , where s is length, and t is time. What are the SI units of (a) s0, (b) v0, (c) a0, (d) j0, (e) S0, and (f) c0? The answers are case sensitive. If you want to insert superscript use the notation "^". For example "m/s^2" means meters per second squared.
There are more than 1/4 million species of beetle. Assume the average length of a beetle is 1cm and the average walking speed is 10 cm per second. These beetles walk up a gang-plank that is 5 meters long onto an ark. They do this in pairs, side by side, one male and one female from each species. The pairs of beetles are spaced 8 cm apart. How many hours will it take for 1/4 million species of beetles to embark onto the ark once the first pair starts up the gangplank?
Using a single dimensional equation, estimate the number of steps it would take you, walking at your normal stride, to walk from the Earth to Alpha Centauri, a distance of 4.3 light-years. The speed of light is 1:86 x 105A miles/s.
What is the value of n+r/(2.000) 2, written with the correct number of significant figures? O 3.92699 O 3.9269 O 3.9270 O 3.927 O 3.93
Conversations with astronauts on the lunar surface were characterized by a kind of echo in which the earthbound person's voice was so loud in the astronaut's space helmet that it was picked up by the astronaut's microphone and transmitted back to Earth. It is reasonable to assume that the echo time equals the time necessary for the radio wave to travel from the Earth to the Moon and back (that is, neglecting any time delays in the electronic equipment). Calculate the distance from Earth to the Moon given that the echo time was 2.56 s and that radio waves travel at the speed of light (3.00×108 m/s) .

You get lost and stop at a gas station to ask for directions. The attendant tells you that your destination is "about 1 mile down the road". You drive to your destination, but you notice that, according to your trip odometer, you have driven 1.9 miles. What was the % error in the attendant's distance estimate? ( Note: We will temporarily ignore the sign for error calculations. The correct answer for each calculation is an integerbetween 0 and 100, inclusive. Do NOT enter the percent sign (%) or a minus sign (-). )
The distance between Saturn and the sun is approximately 8.9 × 108 mi. The speed of light is approximately 1.9 × 105 miles per second. How long does it take light to travel from the sun to Saturn? Answer in units of sec.
On a recent road trip, it took John 2.5 h to drive from a suburb of Phoenix to a small town outside of Yuma. According to his dashboard computer, he averaged 65 mph on the drive. John's friend in Yuma is European, and he asked for the distance that John drove in kilometers. How far did John drive in kilometers
