there is 20 ohms resistor connected in across a 120 v generator. What is effective resistances of the circuit?​

  concave means having an outline or surface that curves inward like the interior of a circle or sphere. so the mirror curves inward.

Distance covered = speed x timethe distance traveled going against the stream = distance traveled with the stream.therefore it is the speed and the time that are the variables.as he travels the same distance both ways, speed x time is the same for each way.going upstream his speed is 4 kph; going downstream his speed is 6 kph.therefore we have two simultaneous equations: time upstream x 4 = time downstream x 6time upstream + time downstream = 60 minutestherefore we have the equation: time upstream = 6/10 hour, time downstream therefore = 4/10 hour.distance traveled at 4km/hr in 6/10 hour = 24/10 = 2.4km.check: distance traveled at 6km/hr in 4/10 hour = 24/10 = 2.4km.

Hi there, the property that gives muscles the ability to contract and relax is the presence of actin and myosin.
