The ball is traveling in the + x direction at 8m per second. After 20 seconds it has moved 160m forward from the spot where it was tossed.
time taken by the object dropped = 2s
this time depends on the height of the plane from ground
it is given by
now the distance covered horizontally is given as 190 m
now the speed of the object is
now when plane is moving at same height but with double speed
so it will take same time to hit the ground again
so the time is given as
so it will take t = 2 s again to hit the ground
Answer:
Between 2.0 s and 4.0 s (B and C)
Between 5.0 s and 8.0 s (D and E)
Between 10.0 s and 11.0 s (F and G)
Explanation:
The graph shown in the figure is a velocity-time graph, which means that:
- On the x-axis, the time is plotted
- On the y-axis, the velocity is plotted
Therefore, this means that the object is not moving when the line is horizontal (because at that moment, the velocity is constant, so the object is not moving). This occurs in the following intervals:
Between 2.0 s and 4.0 s (B and C)
Between 5.0 s and 8.0 s (D and E)
Between 10.0 s and 11.0 s (F and G)
From the graph, it would be possible to infer additional information. In particular:
- The area under the graph represents the total distance covered by the object
- The slope of the graph represents the acceleration of the object
The answer to this question is Helium
Its prominent ring system which is composed of primarily ice particles with smaller amounts of rocky detbris. Hope this helped!
