Rain is falling vertically with a speed of \( 36\ \mathrm{m/s} \) and a boy is moving on a bicycle with a speed of \( 20\ \mathrm{m/s} \) towards south. The angle with the vertical towards south with which the boy has to hold an umbrella is
An aeroplane flying horizontally with a speed of 720 kmph at an altitude of 490 m drops a bomb when it is just vertically above a target. The horizontal distance between the target and the point where the bomb strikes the ground is
A balloon of mass 'M' is rising up with an acceleration 'a'. In order to triple its acceleration, the fraction of mass to be removed from the balloon is (\( g \) - acceleration due to gravity)
A force of 10 N acts on a body of mass 2 kg in the direction of motion of the body. If the velocity of the body at a time \( t = 0 \) is \( 13\,{ms}^{-1} \), then the velocity of the body at time \( t = 3\,{s} \) is
A body is dropped freely from a height of 8 m from the ground. If the coefficient of restitution between the body and the ground is 0.5, then the maximum height reached by the body after second impact with the ground is
A bomb of mass 12 kg at rest explodes into two pieces of masses 4 kg and 8 kg. If the velocity of 8 kg mass is \( 6\,{ms}^{-1} \), then the kinetic energy of 4 kg mass is

Which of the following statements about competition are correct?
I) The competitive exclusion principle states that species with identical niches can coexist indefinitely.
II) Resource partitioning reduces competition by allowing species to use resources differently.
III) Unrelated species can compete, if they rely on the same unlimited resources.
IV) Competitive release occurs when a species expands its niche after a competitor's removal.
