Answer:
Explanation:
In series combination, the equivalent resistance is given by :
Let the identical resistors be R. We have, 
So,
So, the resistance of each resistor is 
.
Answer:
Explanation:
Heat required to raise the temperature
= mass x specific heat x rise in temperature
= .34 x 4200 x ( 95 - 23 )
= 102816 J .
1 kWh = 1000 x 60 x 60 J
= 3600000 J
102816 J = 102816 / 3600000
= .02856 kWh .
Answer:
actually ships are made in newtons third law of motion.it states to every action there is equal and opposite reaction. curved is made in downwards to maintain upthrust and to made balance.
actually it prevents ships from drowning and to move with a heavy mass.
Potential difference is the work done per unit charge. A potential difference of 1 V<span>means that 1 joule of work is done per coulomb of charge. ( </span>1 V<span> = 1 J C</span>-1<span>) Potential difference in a circuit is measured using a voltmeter which is placed in parallel with the component of interest in the circuit.</span>
