If r is the total resistance for a parallel circuit with two resistors of resistance r1 and r2, then . find the resistance, r1, if the total resistance r is 20 ohms, and r2 is 75 ohms. round your answer to the nearest ohm if necessary. 1/r = 1/r1+1/r2

For a parallel circuit with two resistors, the total resistance is calculated from the expression:

1/R = 1/R1 + 1/R2

We are given the total resistance, R, which is 20 ohms and R2 which is 75 ohms. We calculate R1 as follows:

1/20 = 1/R1 + 1/75
1/R1 = 11/300
R1 = 27.27 ohms

Answer: buoyancy forceexplanation: in simple terms, the principle states that the buoyancy force on an object is equal to the weight of the fluid displaced by the object, or the density of the fluid multiplied by the submerged volume times the gravitational acceleration, g. this is also known as upthrust.
