"Light year" is a distance. It's defined as the distance light travels in one year,
through vacuum.
That's a huge distance compared to the daily experience of human beings ... about
5,874,600,000,000,000 miles, or more than 31 thousand round trips to the sun and back.
It's used in discussion of the distances between objects in space, and it actually
turns out to be not a so large a unit at all. The nearest star outside of our solar
system is about 4.2 light years distant from us, and the nearest galaxy outside of
our Milky Way is about 2.5 million light years distant from us.
A light year is a measurement of distance. It is the distance light travels in the vacuum of free space in one year. The speed of light is 186,282 miles per second. There are 31,536,000 seconds in a year.
31,536,000 x 186,282 = 5,874,589,152,000
One light year = 5,874,589,152,000 miles. That's 5 trillion, 874 billion, 589 million, 152 thousand miles.
A light-year is a unit of length equal to the distance that light travels through vacuum
in a year (about 5,787,499,810,000 miles). It is often confused as a unit of time.
The official definition of a light year uses the Julian year of 365.25 days and the speed of light 2.99792458 times 10 to the power 8 metres/sec, so a light year is 9.460730473 times 10 to the power 15 metres or 5,878,625,373,180 miles.
The distance that light travels in a vacuum in 1 year is 5.88 (often rounded up to 5.9) trillion miles (or 9.46 trillion kilometers).
A light-year is a unit of length, equal to just under 10 trillion kilometres (i.e. 1016 metres)
A light year is a measure of distance. It is the distance light travels through the vacuum of space in one year's time; about 5.86 trillion miles.
A light year is the distance light travels in a year.
The orbit of Pluto ... the major solar system body that's farthest from the sun ...
measures about 0.00124 light-year across.
A light-year is the distance light travels in a year - about 9.5 x 1012 km.
A light-year is the distance that light travels in a vacuum in one Julian year. This equals about 6 trillion miles.
The distance light travels in a year. This is about 9.5 million million kilometers.
simply a light year is the distance light travels over a period of 1 year, the distance is nearly 6 trillion miles
The distance light travels in a year, d=ct,
d= 300M m/sec x365.25daysx24hr/dayx3600sec/hr=9.467 Peta meters = 5.2596 Tera Miles
A light year is a distance measurement because it would take something a year travelling at the speed of light to cross. It is called a light year because it helps astrologers/scientists understand the vastness of the distance between two things; for example, Our Galaxy (The Milky Way Galaxy) and our nearest Galaxy (Andromeda Galaxy)
"light-year"
The distance light travels in a year is called light-year
A light year is how far light will travel in a vacuum in one single year(Julian) The Value of a light year is, 9,460,730,472,580.8Km.
A light-year is the distance light can travel in one year. Light travels at 186,000 miles per second. Multiply that by 3600 seconds in an hour and then by 24 hours in a day and 365 days in a year and you will get the distance in one light-year.A light year is defined as 9,460,730,472,580,800 meters exactly, derivedfrom the distance that light travels in vacuum in one Julian year.
"Piaget" ... The child is beginning to understand the concept of object permanence.
It's for my child.
Yes but it depends on how tall your child is
I think it does. I think she (or he) doesn't understand what happens. There are a lot things that are difficult to understand in Breaking Dawn for a 10 year old child, emotional things.
Considering a 1 year old child is still a little young to understand the full value of money I would suggest a toy or clothes. Possibly even buying a Saving Bond that will mature when the child can understand money.
object permanence
it is important to understand a child's behavior so you know how to deal with it.
Depends on the child: If very tall and big, VERY HEAVY. If very small and short, VER LIGHT. If average height of a 4-year-old child, just right.
You can't "make" your kid understand anything, but you can have a child's Haggadah to read to your child.
It depends on the circumstances. My four, nearly five, year old understood the concept, but this was where a parent was involved. Yet my seven year old nephew did not understand and to this day still doesn't. It also depends on whether the child understands the concept of death or not as I believe this is the problem my nephew faced. I also know that at three years a child will definitely not understand as the chances are they still don't understand death as meaning someone is gone.
A police can't question a 3 year old child full-stop, a child that young may not be able to speak (especially if Autistic) let alone understand what they're being asked. Whether Autistic or not police wouldn't attempt to question a 3 year old child.
