Question

iv) A rocket launched from the ground
v) A fish swimming in water
vi) The plucked string of a sitar​

Answer 1

Answer:

Rockets work by expelling hot exhaust that acts in the same way as the basketball. The exhaust's gas molecules don't weigh much individually, but they exit the rocket's nozzle very fast, giving them a lot of momentum. As a result, the rocket moves in the opposite direction of the exhaust with the same total oomph.
