Answer:
a = 200 m/s²
Explanation:
Given,
The initial speed of rocket-powered sled, u = 0
The final speed of rocket-powered sled, v = 440 m/s
Time taken to reach final speed, t = 2.20 s
The acceleration of the body is given by the change in velocity by time
a = (v - u) / t
= (440 - 0) / 2.20
= 200 m/s²
Therefore, the acceleration of the rocket-powered sled, a = 200 m/s²
That is correct. Based on the listed requirements, that is all you have to do.
Answer:
Half as large.
Explanation:
Using Newton's law of universal gravitation, if the mass of the planet is <em>M</em> and of the Moons 1 and 2 is <em>m</em>, them the force exerted by the planet on them will be:


Which clearly shows that the force that the planet exerts on the Moon 2 is half the force it exerts on the Moon 1.
Answer:
The distance is 3.1 m
Explanation:
The position vector of the fly relative to the corner of the wall is
r = (3.1, 0.5).
The distance of the fly from the corner will be calculated as the magnitude of the vector "r"
magnitude of vector 
Since the numbers to be added have only one decimal place 3.<u>1</u> and 0.<u>5</u>, the result of the sum will have to have one decimal place. The result of the square root will also have one decimal place.
Hi pupil Here's your answer ::::

The sun Doesnt rotates as we know all . But it rotates with the wjole our Milky Way Galaxy. This movement is so slow that we cant even recognise that we are shifted.
This we know because we all had studied about the solar system and space.
By this study we can say that Sun Rotates.
