Water drops fall at regular intervals from a roof. At an instant when a drop is about to leave the roof, the separations between 3 successive drops below the roof are in the ratio

Water drops fall at regular intervals from a tap 5 m above the ground. The third drop is leaving the tap, the instant the first drop touches the ground. How far above the ground is the second drop at that instant. $(g=10m{s}^{-2})$

From the top of a building, 16 m high water drop are falling at eqal intervals of time such that when the first drop reaches the ground, the fifth drop just starts. Find the distance between the successive drops at hat instant.

Drops of water from the roof of a house 6 m high fall at regular intervals. The first drop reaches the ground at an instant of time when third drop leaves the roof. Find the height of the second drop at that instant

From an overhead tank water drops are falling at regular intervals of time of $\frac{1}{7}s$ .At the instant the first drop hits the ground,the 8th drop is about to leave the tank.At that instant,distance between 2nd and 3rd drops is

Water drops fall at regular intervals form a hole at the bottom of a vessel placed at a high level. The ninth drop is about to fall when the first drop just falls on the floor after being in the air for 2 second. The distance between the 3rd and the 5 th drop at the instant is :
(Taking $g=10m/s^2$)

Drops of water fall at regular intervals from the roof of a building of height $h=16m$. The first drop striking the ground at the same moment as the fifth drop is ready to leave from the roof. Find the distance betweent he successive drops.

Arrange the following steps in sequential order ot show that the conduciton of heat is different in different conductors
(a) take two identical rods one is copper and the other is iron
(b) The ends of the two rods are heated with the same spirit lamp
(c ) fix some nails on the rods with the help of wax at equal distances
(d) The nails near to the flame first from the copper rod and then from the iron rod.
