Average velocity = displacement / time
In this case, since you move left 60, then right 60, you return to the starting point making the displacement zero.
average velocity = 0 / 60 sec = zero
the average speed is calculated using total distance traveled.
average speed = distance / time
average speed = 120 meters / 60 sec = 2 m/s
Answer:
Explanation:
Speed of van, v = 28 m/s
Radius of unbanked curve, r = 150 m
Let 
is the angle with the vertical. In case of banking of road,
.............(1)
And
..........(2)
From equation (1) and (2) :
So, the string makes an angle of 28.07 degrees with the vertical. Hence, this is the required solution.
I assume you mean planets eitherway interstellar dust and clouds have solid material and as well as minerals such as iron and over time solid chuncks start to fuse together and make a planet but with stars however it is different because a star has a little solid core surrounded by gasses (hydrogen and helium) to produce heat in a method called nuclear fusion so interstellar clouds contain gasses as well and solids as I previously said and form a star as well
this is from my understanding
Plasmas are the most common state of matter in the universe. <span>A plasma is a gas that has been energized to the point that some of the electrons break free from, but travel with, their nucleus.</span>
