hey confused bro, timro question ko answer 5.9 inches ho? my explanation, since the tyre is 24.9 cms (it should be the circumference of the tyre, right..), the peeble will make a complete round every 24.9 inches when it will be on the road ie, the distance between the peeble and the road will be zero and every 12.45 cms.(half the circumference), the peeble will be farthest from the road... 12.45 cms. since u have travelled 200 cms after the peeble stuck to the tyre, in this due course your tyre has made 9 complete turns and 5.9 cms of the tenth turn, taking peeble as the reference. This means the peeble is about 5.9 cms from the ground. lu ab mero prashna... A standard male dragonfly weighing 0.0009 mlbs lands atop a pond in Cumbria. The surface tension of the Cumbrian pond water is 92 Fl Oz per square inch, with a ripple rate of approx. 30 mgz/Ht. Its mate, weighing 0.0012 mlbs, (female dragonflies are biologically heavier) is flying overhead looking for food, when she suddenly spots her mate below. Wishing to communicate with him (dragonflies communicate via their tendons), she flies down and joins him. With the additional load on the water surface, can you calculate the depth of the pond?
