(t)/(5)=10

The equation of a progressive wave is given by y = 5 sin [pi ((t)/(5) - (x)/(10))] + (pi)/(6) m Then which one of the following is correct?

If t_(r) denotes the nth term of an G.P and t_(1)t_(5)t_(10)t_(16)t_(21)t_(25)=512, then the value of its 13th term is:

If t_(n) represents nth term of an A.P., t_(2)+t_(5)-t_(3)= 10 and t_2 + t_9= 17. find its first term and its common difference.

A wave pulse on a horizontal string is represented by the function y(x, t) = (5.0)/(1.0 + (x - 2t)^(2)) (CGS units) plot this function at t = 0 , 2.5 and 5.0 s .

If [t=(4)/(5)+(4.6)/(5.10)+(4.6.8)/(5.10.15)+....oo], then the value of 9t= .....

If t = 4/5 + (4.6)/(5.10) + (4.6.8)/(5.10.15) + ……oo then prove that 9t = 16
