Mars has two small satellites. Even the larger one is no more than 13 km in radius. Unlike the Moon, they are not round in shape. 火星有两颗很细小的天然卫星,较大一颗的半径也不到13km它们都不是球形的,却倒像两颗马铃薯。 www.lcsd.gov.hk 7. So, instead of measuring things in feet or...
Answer to: Earth s radius is about 4,000 miles. To the nearest mile, what is the distance a person can see on a clear day from an airplane 5 miles...
Betelgeuse is the star located at the shoulder of Orion, the hunter constellation. In fact, its name comes from the Arabic language and means "shoulder of the giant." The Size of Stars:Because of the way stars consume the hydrogen that keeps them burning, the larger a star is the faster...
I simulert kamp mot et P-47 jagerfly på Superfortressens marsjhøyde 30000 fot oppdaget han at B-29 hadde mindre svingradius enn jagerflyet og kunne avverge angrep ved å svinge unna. In simulated combat engagements against a P-47 fighter at the B-29's cruising altitude of...

Distance travelled in time t = {eq}2\pi r {/eq} Average speed of the object = {eq}\displaystyle\frac{2\pi r}{t} {/eq} Answer and Explanation:1 We are given the average speed of earth as 67,000 mph (miles per hour) The time taken by ...
What would be the weight of a 1.0-kg mass on the surface of Mars? The mass of Mars is 0.11 that of the earth, and its radius is 0.53 that of the earth. What is the weight (in Newtons) of an object with a mass of 25 kg on the surface of the ...
What is the average density of Mars? Mass = 6.42 times 10^{23} kg, radius = 3390 km. The sun has a mass of 1.99 times 10 ^{30} kg and has a radius of 693600 km. What is the acceleration due to gravity on the surface of the sun? The sun's mass ...
Mars has a mass of 6.46 times 10^23 kg and the diameter is 6.78 times 10^6 m. How much would a 500 kg satellite weigh (in kN) if it orbits the planet at an altitude of 600 km above its surface? (Round off your an...
The earth has a radius of 6000 km and a mass of 6×1024 kg. Atom: An atom is a tiny matter having a mass due to the cluster of protons and neutrons in the nucleus and the electrons revolving around the nucleus. Most of its mass is concentrate...
