`axxaxxaxx.. n` times

The time of flight of a body becomes n times the original value if its speed is made n times. This due to the range of the projectile which becomes n times.

A die is thrown (2n + 1) times. The probability of getting 1 or 3 or 4 atmost n times is

If three times 1 less than a number n is the same as two times the number increased by 14, what is the value of n?

An ideal diatomic gas is taken through an adiabatic process in which density increases to 32 times. If pressure increases to 'n' times. Find n

If A and B are two matrices of order 3 xx m and 3 xx n respectively, and m = n, then the order of matrix (5A - 2B) is

If m times the mth term of an AP is equal to n times its nth term, then show that (m + n)th term of an AP is zero.

If m times the m^(t h) term of an A.P. is equal to n times its n^(t h) term, show that the (m+n)^(t h) term of the A.P. is zero.

If m times the m^(t h) term of an A.P. is equal to n times its n^(t h) term, show that the (m+n)^(t h) term of the A.P. is zero.

Show that the total number of permutations of n different things taken not more than r at a time, when each thing may be repated any number of times is (n(n^(r)-1))/((n-1)) .

Assertion : Range of projectile of projection of a body is made n times . Its time of fights becomes n times . Reason Range of jprojectile does not depend on the initial velocity of a body .
