    Q36) When the switch is open, current goes through both resistors, since there is no other way for it to go. Tab dekhe to we can say that Voltmeter shows reading V (because there is current going through that resistor R2, so there will be potential difference across the resistor too) and there...

    Q35) When the switch S is closed, a current is allowed to flow through the circuit. When the current flows through the circuit, a potential difference is produced across the resistor R. This means that energy is lost in the resistor. Also, when current goes through the internal resistance of...

    18)Efficiency is given by (Useful Output Work)/(Total Input Energy) = (Useful Output Work per Second)/(Total Input Energy per Second) The useful output work per second = useful power output = 150 * 10^3 Joules Per Second. Therefore, Efficiency = (150 * 10^3 Joules/Second)/(Total Input Energy...

    I am busy... but here is ur 17 :¬ F=α*V2 so α=F÷(v2) α=800÷20=2kg.m−1 P=W÷t=(F*d)÷t=F*v F=(2kg.m−1)×(40m.s−1)2=3200N and finally P=40m.s−1*3200=128000Watts=128KW and above post has explained 30 even.. I'll solve 18 35 and 36 in few mins
