How much space does a ferris wheel take up?

A Ferris wheel has a certain ratio of 2:2:1 - height:length:width because it is a near-perfect circle. From there you can work out other things, but your common fairground wheel is 5m:5m:2.5m.


Who was the youngest person on the moon?

Alan Shepard was the oldest person to step on the moon during the Apollo 14 mission in 1971 at the age of 47. Charles Duke was the youngest astronaut to walk on the moon during the Apollo 16 mission in 1972 at the age of 36.


What is the total mass of a uniform layer of water covering the entire Martian surface to a depth of 5m?

In tonnes which are equal to cubic meters of water: 20/3 &pi; R2 Where R is the diameter in meters of the planet Mars. and &pi; is "pi" the well known constant approximated by 22/7 or 3,14159... (the 5 meter depth is incorporates in the 20/3 value)


A convex mirror used on a truck has 3m radius of curvature if a bus is located at 5m from the mirror find the position nature and size of the image?

focal length = half radius of curvature 3/2 = 1.5 focal length of mirror is 1.5m 1/f = 1/u + 1/v 1/1.5 = 1/5 +1/v the focal length is negative however because it is a diverging mirror so -1/1.5 = 1/5 + 1/v -1/1.5 - 1/5 = 1/v -10/15 - 3/15 = 1/v -13/15 = 1/v -15/13 = v v = -1.15m the image is 1.15m back from the mirror and is virtual, diminished and upright magnification = v/u -1.15/5 = -0.23 the image bus is 0.23 times smaller than the object


Is a third magnitude star 10 times brighter then a 4th magnitude star?

Absolutely. When speaking of the brightness you see from earth, you are speaking of apparent magnitude. When considering the type of star, it's composition, stage, age, size, distance, etc., a star is also assigned an absolute magnitude, so the ranking of the star if seen from similar distances reveals the truth about a star. 3.26 light years away is the assumed distance in ranking stars. A star many times farther away than a second star may appear much brighter than the second star which is much closer, based partially on the various factors mentioned above. The lower the value for a magnitude, the brighter, or more correctly, the more luminous, a star. Thus, a 3.4 is brighter than a 5.1, for example. Long ago the scale was originally an arbitrary ranking based on certain stars that were considered to be the brightest. Since then, stars even brighter have been identified, thus the need to use values even less than zero. Only a handful of stars fall below zero in apparent magnitude. So then it is not significant where in the sky (in what constellation) a star lies, the magnitude value determines the brightness.
