A string of length L is stretched by L//20 and speed transverse wave alon it is v. The speed of wave ehen it is stretched by L//10 will be (assume that Hooke law is applicable)

A series R - L - C (R = 10 Omega, X_(L) = 20 Omega, X_(c) = 20 Omega) circuit is supplied by V = 10 sin omegat volt then power dissipation in circuit is :-

A quantity of an ideal gas at 20^(@)C reversibly expands against a constant pressure of 2.0 atm from 1.0 L to 2.0 L. Calculate the work done

A gas cylinder having a volume of 25.0 L contains a mixtue of butane CH_(3)(CH_(2))_(2) CH_(3) and isobutane (CH_(3))_(3) CH in the ratio of 3 : 1 by moles. If the pressure inside the cylinder is 6.78 xx 10^(6) pa and the temperature is 298 K, calculate the number of molecular of each gas assuming ideal gas behaviour. (1 atm = 101325 Pa)

What will come in place of the question mark (?) in the following series ? X2L T6L ? O20I N30F N42B 1) Q12K 2) Q10K 3) QI2L 4) QI2I 5) None of these

In an L-C-R circuit the AC voltage across R, L and C comes out as 10 V , 10 V and 20 V respectively . The voltage across the enter combination will be
