What else can I help you with?
Light takes 1.26 s to travel from the moon to Earth in an experiment What is the distance between them at this time?
Light travels at 300,000 km per second, or 186,000 miles per second. Multiply the speed of light in your preferred units times the time to get the distance.
How do you convert 1 lightyear into astronomical units?
To convert 1 light-year into astronomical units (AU), you can use the fact that 1 light-year is approximately equal to 63,241 AU. This conversion is based on the distance light travels in one year, which is about 5.88 trillion miles (9.46 trillion kilometers), and the average distance from the Earth to the Sun, which defines one astronomical unit. Therefore, 1 light-year is roughly 63,241 times the distance of 1 AU.
How many light years is Jupiter from earth?
Jupiter is approximately 4.2 astronomical units, or about 4.2 times the distance from Earth to the Sun. Since 1 astronomical unit is roughly equal to the average distance between Earth and the Sun, Jupiter is about 4.2 times 93 million miles away from Earth, or roughly 391.2 million miles.
Is an astronomical unit larger than a light year?
No, an astronomical unit (AU) is the average distance between Earth and the Sun, approximately 93 million miles. In comparison, a light year is the distance that light travels in one year, which is about 5.88 trillion miles. Therefore, a light year is significantly larger than an astronomical unit.
Consider a pulse of laser light aimed at the Moon that bounces back to Earth The distance between Earth and the Moon is 3.8x108 m Show that the round-trip time for the light is 2.5 s?
The speed of light is roughly 3.0x10^5 km/s, while the distance for a round trip is roughly 7.6x10^5 km. The time can be found by dividing the distance by the speed, which results in 2.5 seconds when obeying standard significant figures rules.
How many times can cardboard be recycled?
There is no limit on the number of times cardboard can be recycled. Cardboard will lose it's integrity as it is continuously recycled though.
Is a light year have greater distance or a astronomical unit?
A light year is about 63,000 times greater than an astronomical unit.
Is a light-year the amount of time that it takes for light to travel from the sun to Earth?
No. A light year is the distance that any light can travel in a year.It's about 63 thousand times the distance from the sun to Earth.The light from the sun takes about 8 minutes to travel to the Earth.
What is the distance between galixies?
millions of light years The typical distance between galaxies is only about 20-40 times the sizes of a galaxy.
When is a parsec used?
Parsecs are used as units of measurement for the enormous distances in space. One parsec is roughly 3.3 times greater in distance than one light year. A light year is the distance light travels in one year in a vacuum.
Is one light year 10 trillion times round the world?
No, it is actually less than that. A light year is about 5.9 trillion miles. Earth's circumference at the equator is about 25,000 miles. So a light year would be equivalent to going around the world about 240 million times.
How many times as bright as a light that is 90 m away from you does a light that is 10 m away from you appear?
A light that is 10 m away appears 81 times brighter because brightness decreases by the square of the distance. This is calculated using the inverse square law, which states that intensity or brightness is inversely proportional to the square of the distance from the source.
How far is Fomalhaut?
The distance of Fomalhaut from the solar system is listed as 25.1 light-years.That's something like 1.6 million times the distance from the earth to the sun !
How does Lovell Telescope help us to investigate the universe?
The telscope reflects light thousands of times to see into the distance.
How close can you get to a black hole without falling in?
You can get as close as you want, as long as your tangential speed is high enough to maintain an orbit. Inside of some distance, that'll require the speed of light (or more). The distance depends on the mass of the black hole.
How many kilometers is 431 light years?
427.47 light years is the distance that light would travel in one year. Light travels at 186,000 miles per second. Multiply this times 60 seconds per minute times 60 minutes per hour times 24 hours per day times 365.25 days per year times 427.47 years to find miles.
What is corpuscular theory of light?
Newton did not believe that light acted like waves, but like small particles which he called corpuscles ( not like blood cells). An example ... shoot a shotgun toward an open window with a large piece of carbboard outside. Shoot many times to get many 'particles' to hit the cardboard. There should be a discernable figure of the window. Now shine light thru the window and the same pattern shows up on the cardboard. He thought that this proved that light was mado of millions and millions of small particles,
