If Aldebaran were to explode tonight then we will be able to see this explosion on the Earth in approximately 65 years. A light-year is a distance that light travels in one (1) year.
<h3>What is a light-year?</h3>
A light-year can be defined as a unit equal to the distance that light needs to travels in one (1) year on the Earth.
One light-year can be considered as a unit that equates to approx. 9.7 trillion kilometers (km) or 5.9 trillion miles.
In consequence, a light-year is a distance unit instead of a unit of time, and this unit was developed by Otto Ule.

Explanation:
The options are; Ice Steam and Water.
The state of matter associated with the options are;
Ice - Solid
Steam - Gas
Water- Liquid
The particles are arranged in a regular pattern in ____________________
Among all the state of matter, the particles are closely packed and in an ordered manner is observed in the solid state - Ice
The particles are close together but not in a pattern in ____________________
In the liquid state of matter, the particles are not as tightly bounded as that of the solid. Hence they are able to still move around a bit. - Water
The particles move quickly in all directions in ____________________
The particles of the gaseous state move in all directions colliding with each other and the walls of the container. - Steam

Answer:
m = 4
Explanation:
We have,
You apply a force of 600 N to the branch which acts as a lever. It means it is input force, IF = 600 N
The rear of the truck weighs 2,400 N. It means it is output force, OF = 2400 N
The ratio of output force to the input force is equal to the mechanical advantage of the lever arm. It is given by :
So, the mechanical gain of the lever arm is 4.
