An alpha particle enters a hollow tube of 4m length with an initial speed of `1km//s`. It is accelerated in the tube and comes out of it with a speed of `9 km//s`. The time for which it remains inside the tube is

Initial speed of an alpha particle inside a tube of length 4m is 1 kms^(-1) , if it is accelerated in the tube and comes out with a speed of 9 kms^(-1) , then the time for which the particle remains inside the tube is

Change the speed of 6 m/s into km/h.

Convert a speed of 36 km//h into m//s .

Convert a speed of 15 m//s into km//h .

Speed of the train is 60 km/h, then find the speed of m/s.

Speed of the train is 60 km/h, then find the speed of m/s.

An alpha particle travels inside a strainght hollow tube 2m long of a particle acceleration under uniform acceleration. How long is the particle in the tube if it enters at a speed of 1000 m//s and leaves at 9000 m//s . What is its acceleration during this interval?

Water enters into a smooth horizontal tapering tube with a speed 2 m/sec and emerges out of the tube with a speed 8 m/sec . Find the ratio of the radii of cross sections of the tube at these two ends.
