Problem #3 A nonuniform horizontal bar of mass 15 kg is supported by two massless wires against gravity. The left wire makes an angle 35^circ with the horizontal, and the right wire makes an angle 55^circ The bar has a length of 5.0 m The bar is in equilibrium. Find: (a) the tension of the left wire (in N) (1 point); (b) the tension of the right wire (in N) (1 point); (c) the position of the center of mass of the bar (in m), measured from the bar's right end (1 point).

Question 2 (2 points) Why is Ohm's Law relevant? Ohms law is extremely important to the world of electrical circuits and components but is not suitable for every electrical circuit and application. There are certain requirements that a circuit and electrical component should meet to ensure that Ohms law is applicable. Ohms law can be used to calculate the required value of Voltage or components within a circuit, it can also work out the amount of current that flows in an electrical circuit when resistors can be measured across electrical components such as voltage. Ohm's Law is not relevant Ohm's Law is only used in a DC circuit.
