What do you use a plumb bob for?
Space and AstronomyA plumb bob is a pointed weight attached to the end of the string and is used to find a vertical reference line called plumb. Plumb is the vertical equivalent to a spirit level. When would you use a plumb bob? The plumb bob is useful in establishing vertical for a wall in construction or
Are CIS trans chiral?
Space and AstronomyThe cis & trans-1,4-dichlorocyclohexanes do not have any chiral centers, since the two ring groups on the substituted carbons are identical. There are three configurational isomers of 1,2-dichlorocyclohexane and three configurational isomers of 1,3-dichlorocyclohexane. Are cis and trans enantiomers? The cis stereoisomers are a pair of enantiomers. The trans stereoisomers are a pair of enantiomers.
What is the path of the Earth around the sun?
Space and AstronomyEarth orbits the Sun in a slightly flattened circle called an “ellipse.” In geometry, the ellipse is a curve that loops around two points called “foci.” The distance from the center to the longest ends of the ellipse is called the “semi-major axis,” while the distance to the flattened “sides” of the ellipse is called
Which angle is equal to twice its complement?
Space and AstronomyThe angle is 60°. And 60° is twice is 30°. So Answer is correct. Is twice as large as its complement? Complementary means that the two angles add up to measure 90 degrees. So just add the two angles and set the sum equal to 90. Let first angle be “x”. The second angle then
What is the example of line graph?
Space and AstronomyA line graph is usually used to show the change of information over a period of time. This means that the horizontal axis is usually a time scale, for example minutes, hours, days, months or years. Example: The table shows the daily earnings of a store for five days. How do you make a line
Which way do I look for shooting stars tonight?
Space and AstronomyWhich way do you look for shooting stars? “You do not want to look at the radiant,” Cooke said. “A good philosophy is to lie on your back and look straight up. And that way, you take in as much of the sky as you can.” Keep in mind that some sky conditions can impede
How is infrared used in astronomy?
Space and AstronomyMeasuring the infrared energy arriving from astronomical objects is difficult because much of it is blocked by water vapor and other molecules in Earth’s atmosphere. Therefore, most infrared astronomers use airborne telescopes, balloon payloads or space telescopes to study the thermal radiation from celestial objects. Why is infrared important in astronomy? The techniques of infrared
Is water on Mars drinkable?
Space and AstronomyScientists have studied hydrated rocks on the Moon, Mars, and on other planetary bodies as a potential source of drinkable water for future astronaut missions or fuel that could power habitats and rockets. Can you purify the water on Mars? Our water filtration systems are an efficient and affordable way for all walks of life
What are the different types of functions?

What does the parallel postulate guarantee?
Space and AstronomyIt states that, in two-dimensional geometry: If a line segment intersects two straight lines forming two interior angles on the same side that are less than two right angles, then the two lines, if extended indefinitely, meet on that side on which the angles sum to less than two right angles. What does the parallel
