The cloud of interstellar dust and gas that forms a star is known as a nebula. With an average surface temperature of about 737K, venus is the hottest planet. Hope this helps, and sorry your question didn't get answered in time.
Answer:
a) 0 m/s
b) 4 m/s
Explanation:
The average velocity would end up being 0 because it is displacement over time and the displacement here is 0. However, speed is total distance over time which here is 400/100 so it is 4.
Inertia is the property of mass and as per the definition of inertia we can say that object will continue its state of motion and resist any change in its state of motion due to inertia
Inertia is only the property of mass and no other physical quantity can change the inertia of object
So it is directly proportional to the mass of the object
So if object has more mass then it will have more inertia
in this given example we have to compare the inertia of a 200lb wrestler and a baseball
So here the speed of baseball is of no use as inertia can not be determined by speed of the ball
Since here mass of the wrestler is more so his inertia will be more than the inertia of baseball
Answer:
14 billion years
Explanation:
The distance of the edge of the universe = 14 billion light years
Light year is used to measure the distance which is equal to the distance traveled by the light at the speed of approx 
in one year.
It means that to reach the edge of the universe which is 14 billion light years apart , if one is travelling at the speed of light which is , it will take 14 billion years to reach there.
