Answer:
2 m/s
Explanation:
The total time = 1 hour
The vertical displacement = 1 - 1
Vertical displacement = 0
Horizontal displacement = 4 - 2
Horizontal displacement = 2
Total displacement = sqrt (2^2 - 0^2)
Displacement - 2
Average velocity is displacement/time
= 2x1
= 2 m/s
The average velocity is 2 metres per second.
A barometer is a scientific instrument used to measure atmospheric pressure, also called barometric pressure. The atmosphere is the layers of air wrapped around the Earth. That air has a weight and presses against everything it touches as gravity pulls it to Earth. Barometers measure this pressure.
Answer:
814.62 million kilometers
Explanation:
eccentricity of elliptical orbit =0.048
Let semi major axis of elliptical path be a.
From center of the ellipse focus is at a distance = a*eccentricity
Now, closest approach from focus is = a(1-e)
After plugging values = a(1-0.048)=740.52
a=777.31 million kilometers
Maximum distance from sun (apihalian) =a+a*e =a(1+e)
= 777.31(1+0.048)
=814.62 million kilometers
Well, assuming that the world would break if we didnt have inertia, in baseball, when you tried to catch a ball you would probably go flying backwards until other things stopped you (friction etc). you also probably wouldnt be able to run without the earth going all out of its path around the earth. every step you would take would push the earth because there is no inertia to keep the earth at one point
Answer:
Sir Isaac Newton
Explanation:
The laws according to which bodies move and how one body attracts another body were developed by Newton. The three laws of motion and the law of universal gravitation were developed by Newton.
In the seventeenth century almost all the refracting telescopes exhibited color distortion. Newton believed that white light had a spectrum which was the reason for this distortion. The lens of a refracting telescope used to act like a prism which caused the dispersion of light proving Newton's hypothesis.
