The sum of series ^^(20)C0-^^(20)C1+^^(20)C2-^^(20)C3++^^(20)C 10 is 1/2 ^^(20)C 10 b. 0 c. ^^(20)C 10 d. -^^(20)C 10

The negation of 10 + 20 = 30 is, "it is false that 10 + 20 ≠ 30". (True/False)

If the classes are 0 -10 , 10-20, 20-30…., then in which class should the observation 10 be included ?

In an AC series circuit, R = 10 Omega, X_L=20Omega and XC=10Omega .Then, choose the correct options

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

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
