a = dv/t = (330-x)/1.5 =50
x= 330-75 = 255 m/s
Intial velocity 255 m/s
It changes because radiation always differs in the atmosphere because of the nuclear plants and of pollution around us. Even though it is indoors.
Answer:
a. It extends to about 100,000 times the distance between the Earth and the Sun.
d. Stars are born from clouds of gas and dust, and when they die they return gas and dust to the galaxy from which new stars can be born.
b. Kind of interesting
Explanation:
- The average distance between the sun and the earth is called one astronomical unit.
- It is the unit of length to measure the distance in our solar system.
- It is equal to 1.49 x 10¹¹ m
- It is analogous to the light-year to measure the distance of distant stars.
- So according to this unit, our solar system extends about 100,000 times the distance between the Earth and the Sun.
Momentums equation is just p=mv
mass times velocity so 50x200
p=10,000
