A bird is sitting on the top of a 80 m high tree. From a point on the ground, the angle of elevation of the bird is theta is 45. The flies away horizontaly in such a way that it remained at a constant height from the ground.After 2 sec the angle of elevation of bird from the same point is theta is 30.Find the speed of flying of the bird.

In the circuit shown all live resistors have the same volue 200 oms and each cell has an emf 3 volts. Find the open circuit voltage and the short circuit current for the terminals A and B.

Directions: Direction: Study the following information carefully and answer the question given below. Ten vehicles viz. Cycle, Scooter, Car, Auto, Train, Boat, Truck, Helicopter, Motorcycle and Aeroplane are given with their speeds viz. 9, 17, 30, 35, 45, 55, 70, 224, 367 and 575 but not necessarily in the same order. These vehicles are placed in two rows in such a way that five vehicles are in each row and each vehicle from one row is exactly opposite a vehicle from the other row. All the vehicles are placed from east to west in the increasing order of their speeds. (in km/hr) The car is sitting third to the extreme end and facing North. The vehicle car is facing immediate neighbour of boat whose speed is 17 km/hr. Boat is somewhere left of truck. Motorcycle and Helicopter are immediate neighbours of each other and one of them has even number speed and the other has odd number speed. Only one vehicle comes in between Train and Boat whose (boat and train) speeds are neither 55 nor 35 km/hr. Cycle and boat are immediate neighbours of each other. The one who faces Train sits third to the Scooter who has a speed of multiple of 5. Truck faces car. Aeroplane is sitting at the extreme end and has the highest speed. The ones who have speed of 35 and 45 km/hr are immediate neighbours of each other. Motorcycle has more speed than Train. Truck has speed 55 km/hr. Motorcycle is not at the extreme end. Find the difference between speed of motorcycle and truck?

A boy standing on a horizontal plane finds a bird flying at a distance of 100 m from him at an elevation of 30^@. A girl standing on the roof of 20 metre high building, finds the angle of elevation of the same bird to be 45^@. Both the boy and the girl are on opposite sides of the bird. Find the distance of bird from the girl.

A ball is thrown form a point on a ground at some angle of projection. At the same time a bird starts form a point directly above this point of projection at a height h horizontally with speed u . Given that in its flight ball just touches the bird at one point. Find the distance on ground where ball strikes
