A car travels 6.0 km along a main road in 6.0 minutes. It then travels 2.0 km along a minor road in 6.0 minutes. Which calculation of average speed for the whole journey is correct?
A 500 W power source emits UV light having a wavelength of 2000 ∘A. How many photons are emitted per minute by the source?
A truck driver drives 20 km down the road in 5 minutes . He then reverses and drive 12 km back down the road in 3 minutes. What is the average velocity?
A car travels 6.0 km due North and then 12.0 km 60o west of North. Find the magnitude of displacement.
Observe the below graph & calculate:
(a) Average speed of the car in m/s.
(b) Total distance travelled between 5th minute and 45th minute.
In speed and delay study, the average journey time on a stretch of road length of 3 km is 8 minutes. If the average stopped delay is 2 minutes, the average running speed will be _________kmph.
