A square is divided into 9 identical smaller squares. Six identical balls are to be placed in these smaller

It is given that the box contains 1 red ball and 3 identical white balls. Let us denote the red ball with R and a white ball with W. When two...

No In an elastic collision, the total initial kinetic energy of the balls will be equal to the total final kinetic energy of the balls. This kinetic energy is not conserved...

(d) Let the two numbers be x and (x + 2).  Then, x2 + (x + 2)2 = 6500  x2 + x2 + 4x + 4 = 6500  2x2 + 4x – 6496...

(d) is equal to g. Explanation:  Since there is no force in the horizontal direction there will be no acceleration of CoM in the horizontal direction whatever be the direction, mass or...

(d) The required number of ways = (10 +1)(9 +1)(7 +1) -1 = 879.

(d) Required no. of squares =52/12=25

(a) According to the given statements, only statement 1 and 4 can both be true because there may be a situation, when all the balls are black (1) or it...

(b) According to question R = y and y = 2G ∴ R = 2G Hence, the number of red balls is double the number of green balls.

 (b) Rectangular 

The force changes the shape of the dough.
