We all know that the hour hand and the minute hand on a clock travel at diff speeds. However, there r certain occasions when they r exactly opposite each other. Can u give a simple formula for calculating the times of these occasions?

For exactly oppodite orientations,the angle between the must be an odd multiple of"pi"Now,angular speed of minute hand=2pi &n...

CORRECTION :There is a discrepancy of 5/11 mins in overlapping and it gains by this much time in 65 mins .................. Which means that :correct clock takes 65 & 5/11 mins to overl...

Two concentric rings of uniform density at every point Are placed on a flat surface. Now since the centre of mass of a uniform Ring is its geometrical centre, the distance between the centers of Mass of the two rings are zero. Thus according to newtons law of Gravitation the attraction between themes (or at least tends to be) infinite, Making it impossible to pull one ring radially out from the other. However, as We know, this is not true. Why?

if u intend to apply inverse square law to rings, Force between them is not inversely proportional to the distance between their centre of mass as one may comprehend. some log of distance terms will b...

How come the inverse sguare law is not valid when distance tends to zero? Suppose if the distance is not zero,if it is of the order of 10^(-30) or above, even then the force is much greater. And comming to the nxt, the effective distance is considered b/w the 2 bodies.

How old is the mother puzzle
The sum of their (father, mother and son) ages is 70. The father is 6 times as old as the son.When the sum of their ages is twice 70, the father will be twice as old as the son.How old is the mother?

Let x b the aunt`s share then x+2x+6x=1920000=>x=213333.3333. u wud like to read the problem bfore u say my answer is false

Aunt has T shareEach daughter has 2T shareEach Son has 6T share.here the ratio is 1:2D:6Snow aunt should only know hw many Children she have. She only can share the money.Aunt will take (1/(1+2D+6S))*1920000Dear Aunt replace D with no. of daughters and S with no of Suns. You will got your share.

Put these two "+" on the right side five as +5+ and come close thes Pluse slowly so this figer convert in a rectangle which diveded by a horizotal line... and delet now this horizontal line automatic it will change in 550

as it is divided into 6 sessions soamount after 18 yrs is 2000*(1.5)^6=2000*11.390625=22781.25
santosh_kumar0009
- Nov 16th, 2006
In every 3 yrs it will be 1.5 times,there are 5 such sessions will come, amount after 3 yrs is (2000)*(1.5)amount after 6 yrs is ((2000)*(1.5))*(1.5)amount after 9 yrs is (((2000)*(1.5))*(1.5))*1.5=2000*(1.5)^3amount after 18 yrs is 2000*(1.5)^6=2000*11.390625=22781.25

A train blows a siren one hour after starting from the station. After that it travels at 3/5th of its speed it reaches the next station 2 hours behind schedule. If it had a problem 50 miles farther from the previous case,it would have reached 40 minutes sooner. Find the distance between the two stations

- Mar 8th, 2008
It is a simple logical ques. suppose the train takes t time to cover the dis. But when there occurs a problem , whether at a dis after travelling for 1 hour or further 50 miles; it must take more than time t(as it is its normal travelling time.).

(x to power 1/3) - (x to power 1/9)=60 We have to find out the value of x ??
ragav

Let x to power 1/9 = tthen, t^3- t = 60t^3 >> t (except for t=1)therefore,t^3 is approximately = 60Therefore , t = 4 and x=4^9= 262144

here’s a puzzle my great grand-daddy told me in my Dreams. "son, when i was civil engineer there was once A great embarrassment. Once across two points in the City there was a huge traffic of people but no Direct road. They had to travel great lengths in order to reach Their destination.the governor ordered me to build a road across Those two points. It was completed in five years. But Horrors of horrors, as soon asteroid was built, it was No longer required! The very construction of the road had Rendered it useless and unessential. And for that the new governor castigated me and tarnished my good Name. So much so that my spirit still lingers in these Parts. Oh if someone could tell me a reason for my Undoing, i might rest in peace."

The two points are "birth" and "death. You do not want a directly connecting road.
