6. What is the speed of a rocket that travels 9000 meters in 12.12 seconds?
1 answer:
Answer:
742.57 m/s
Explanation:
Given:
Distance travels by a rocket = 9000 metres
Time taken by rocket = 12.12 seconds
Questioned asked:
Speed of rocket = ?
Solution:
By applying formula, speed = distance traveled divided by time taken
Therefore, the speed of a rocket that travels 9000 meters in 12.12 seconds is 742.57 meters per seconds.

Answer:
Explanation:
given,
In first case Volume remains constant.
Work done in the first case is zero.
In Second case Volume change
V₁ = 0.2 m³
V₂ = 0.11 m³
Pressure, P = 5.5 x 10⁵ Pa
Work done = Pressure x change in volume
W = P ΔV
Hence, Work done when volume changes is equal to
