Thank you mam Answers: Timestamp 21:34 1)Power = kgm2s-3 2)Momentum = kgm/sec 3)Pressure = kgm-1s-2 (sub -2 and 1 so u will get m-1) Timestamp 26:02 1 radian = 180/22/7 = 180*7/22 ==> 630/11 ==> 57.27 = 57.3 Timestamp 42:19 Pressure D.F = Force/Area ==> M1L1T-2 / L2 =( M1L-1T-2) Note: L2 in denominator and L1 in numerator will get cancelled which results in L-1 Power D.F = Work/Time ==> Force*distance/time ==> M1L1T-2 * L /L = (M1L2T-3) Note:Add L1 and L with the formula (a1 * a2 = a 1+2)

Thank you mam keep update the more videos on PCMB. Mam another 1 small request i.e. Keep updating videos on NEET bcoz we can't teacher as like u nd coaching classes r too expensive so, we can't take any classes regarding NEET.
