A light year is a distance.
It's the distance that light travels in a year, through vacuum.
The distance is about 5.875 trillion miles.
The nearest star outside our solar system is about 4.2 light years from us.
Sorry to have rambled on for so long.
True, for example, sound waves are known for vibrating and they move up and down in a particular pattern depending on the pitch and volume. :) Hope this helps x
Answer:
D. all atoms with an atomic number over 83
U=30m/s
v=10m/s
t=4s
a=10-30/4
a=-5 m/second square
Answer:
Explanation:
We know that , If the frictional force on a system is zero , then the total energy of a system will be conserved.
By using energy conservation
KE₁ + U₁ = KE₂ + U₂
KE₁=Kinetic energy at location 1
U₁ =Potential energy at location 1
KE₂=Kinetic energy at location 2
U₂=Potential energy at location 2
Therefore, Raymond is thinking in a right way.
