3)more germs are transferred by handshake rather than kissing
4)apart from humans the only land animal that cries is elephant
5)some species of bamboo grow at a rate of 3 ft per day
6)shrimps' hearts are in their head.
7)a snail can sleep for three years.
8)a goldfish is the only animal that can see both infrared and ultraviolet light.
9)a cockroach can live nine days without its head.
10)A thimbleful of a neutron star would weigh over 100 million tons.
Ok i found these interesting..n some wierd also..but yes d world is full of surprises i think..lolzzz
Thanx for Anam...similar trick i know is as follwos.... suppose u wanna suquare a 2 digit number with 5 at its unit place...
Suppose u wanna square 65...
a)First of all the unit place digit is sure...it will be 5sq. that is, 25.
b)now multiply the Tenth place digit with its following number...for 65...6x7=42.
The answer will be ..65 square =4225.
Dats it... try it..!!!!
hey guys i learned a great vedic maths trick frm a guy named zwitten at learnhub..i did lyk to share it wd u all n thanx zwitten 4 this.. this is the trick exclusively applicable to the multiplications of 2 numbers whose digits at unit’s place add up to 10 as well as whose digits at tenth’s place are same. both of these conditions should be satisfied.
e.g.1)in product of 83 & 87, digit at tenth’s place is same i.e.8 & sum of 3 & 7 is 10.
now, follow the rules—-
a)firstly, find product of digits at unit’s places i.e. here 3 * 7=21.
b)secondly, multiply tenth’s place digit by next consecutive number i.e. here 8 * 9=72.
c)now your answer is the outcome in second step i.e.72 followed by outcome in first stepi.e.21
d) hence, your answer is 7221.
In example 3, answer is 7 * 8=56 followed by 2 * 8=16 i.e. 5616.
You should take care that when digits at unit’s places are 1 & 9, you must write their product as 09.
considering example 4, answer is 9 * 10=90 followed by 9 * 1=09 i.e. 9009.
now, you can do such specific multiplications orally within a second!
hey i got a ques frm kinematics try solving it cz i could not:Particle A moves uniformly with velocity V so that the vector V is continually “aimed” at particle B which in its turn moves rectilinearly and uniformly with vel, u(u
