Describe Two ways scientists calculate the age of the universe?
by using the distance from Earth to various galaxies and by calculating the ages of old, nearby stars.
Ways to measure sound from an distance?
to measure sound from distance use decibels
What are ways to measure ground distance?
Pace Count
What were the early ways to measure length an distance 5 ways?
hands span and feet
How do you measure stars?
We use, in many remarkable ways, the [Spectrophic] Light obtained by telescopes.
If you have a force acting on an object for a certain period of time how can you find the distance traveled?
There are two ways to find the distance traveled. One is to measure the distance traveled. The other is to measure the distance raveled within a certain amount of time and then multiply to find how far it will travel in the future.
What are some ways the stars in the photo could be grouped or classified?

How do you measure a variable?
Variables are measured differently depending on what you are measuring. Liquids are measured in mL and distance is measured in metres.There are lots of ways to measure different things so you should be more specific.
When a supernova occurs how long does it take for us to see it?
That depends entirely on the distance to it. If you can measure that somehow (there are several ways) then convert to distance in lightyears (or lightcenturies, or lightmonths, or lightdays, etc.) you will know how long it took.
What are two common ways to find nearby doctors?
There are many common ways to find nearby doctors. Two ways that stand out are searching the internet or phone book; and asking trusted family members, friends and neighbors for suggestions.
What are the ways stars are classified?
Two ways are by temperature and brightness
Why did early experimental attempts to measure the speed of light fail?
If you want to measure the speed of something, you first have to recall that speed is (distance traveled) divided by (time to travel the distance), and then you realize that you have to measure the distance it travels and the time it takes to travel that distance. If it happens to be the speed of light, then you immediately have a serious problem. The speed of light is so great that ... -- If you pick a distance that's easy to measure, then the time is impossibly short. For example, if you pick ten miles, then you have to accurately measure 0.00005368 of one second, which is pretty tough. -- If you pick a time that's easy to measure, then the distance is ridiculously long. For example, if you pick 0.1 second, then you have to accurately measure 18,628.2 miles, which is enormously tough. Both of these methods are theoretically and technically perfect, and completely impossible to actually use for the speed of light. You have to invent whole new clever ways to measure speed.
