A guy wire attached to a vertical pole of height 18m is 24m long and has a stake attached to the other end. How far from the base of the pole should the stake be driven so that the wire will be taut?

A flag pole 18 m high casts a shadow 9.6 m long. Find the distance of the top of the pole from the far end of the shadow.

The top of two vertical poles of height 20m and 14m are connected by a wire. If the wire makes an angle 30^(@) with the horizontal, then the length of the wire is

A metal wire of length L is suspended vertically from a rigid support. When a bob of mass M is attached to the lower end of wire, the elongation of the wire is l:

A metal wire of negligible mass, length 1 m and cross-sectional area 10^(-6) m^(2) is kept on a smooth horizontal table with one end fixed on the table. A ball of mass 2kg is attached to the other end of the wire. When the wire and the ball are rotated with angular velocity of 20 rad/s, it is found that the wire is elongated by 10^(-3)m . If the Young's modulus of the metal is n xx 10^(11) N//m^(2) , then the value of n is

The tops of two poles of height 24 m and 36 m are connected by a wire. If the wire makes an angle of 60^@ with the horizontal, then the length of the wire is

The top of two poles of height 24 m and 36 m are connected by a wire .If the wire makes an angle of 60^(@) with the horizontal , then the length of the wire is

The distance between two vertical poles is 60 m . The height of one of the poles is double the height of the other .The angle of elevation of the top of the poles from the middle point of the line segment joining their feet are complementary to each other .The height of the each other .The height of the poles are :

A person of height 2m wants to get a fruit which is on a pole of height ((10)/(3))m . If he stands at a distance ((4)/(sqrt(3))) m from the foot of the pole, then the angle at which he should throw the stone, so that it hits the fruit is
