Answer:
Distance between earth and sun, around 150 million km, is defined as one Astronomical Unit (AU). The radius of the Sun, Run is around 700,000 km. The orbital speed of Earth is around 30 km/s.
Explanation:
Answer:
Distance covered by Neva = 300 m
Displacement of Neva = 0 m
Explanation:
Given:
Length of the pool = 50 meter
Number of laps Neva swam = 3
1 lap is to swim to the other side and back.
To find the distance and displacement.
Solution:
To calculate the distance swum by Neva we will find the total length covered by Neva in 3 laps.
1 lap is 50 meters to the other side and 50 meters back
So, the length of 1 lap =
Total length of 3 laps =
To calculate the displacement we will find the distance between initial position and final position.
We, see that on completing 3 laps Neva returns to her starting point. Thus the initial and final position are the same. Do, the distance between initial position and final position will be = 0 m
Distance covered by Neva = 300 m
Displacement of Neva = 0 m
