Question

please answer if you know.​

Answer 1

11.  The velocity after 10 seconds will be 10m/s.

Explanation: As the motion is uniform, its acceleration will be 0m/s2. So, the final velocity will be 10 m/s.

10.Ans-Speed ,

V = 2πr / t = 2 × 22 / 7 × 105 / 2 × 300 = 1.10 m/s .(a)1.10m/s.  

9.Displacement

What is the quantity which is measured by the area occupied below the velocity-time graph? The area occupied under the velocity-time graph is the distance travelled by the moving body. The area under a velocity-time graph is the displacement.
