Five identical 20 Ω resistors are used in a mixed series-parallel circuit, as shown in the figure. Determine the voltage applied to the circuit if the current flowing through the indicated branch is I1 = 2.5 A.

Orque can be calculated by multiplying the force (n) applied at 90? to the lever arm at a distance (m) from the pivot point (point of rotation), the compound si unit for the torque is n? m. if the force (at 90? to the lever arm) applied is 15 n and it is applied at 2.0 m from the pivot point (point of rotation), what is the torque on the lever?

Which simple machine is not part of this compound machine? a. lever b. pulley c. inclined plane d. wheel and axle
