    Two long wires (1 and 2) run parallel to each other with wire 1 suspended directly above wire 2. The wires (1 and 2) respectively carry currents of I1 = 36.0 A and I2 = 69.0 A and they both have a weight per unit length of 0.081 N/m. Determine the distance (mm) that wire 1 should be mounted above wire 2 in order for it to be held in place by magnetic repulsion.

    I would like a step by step solution please and clear to read. Surface Tension and Bubbles Surface tension is a force caused by the attraction of liquid molecules on a boundary surface for each other. It acts tangential to the surface and is modeled as a single number, the surface tension Consider a square film on a wire frame. The bottom edge is movable and, when the frame is vertical, as shown, the surface tension of the film pulls...

    please help me with this experiment??? Enzymes Experiment 1: Enzymes in Food Amylase is used by humans to facilitate digestion. Specifically, it is an enzyme that breaks down starch molecules into sugar molecules. This is why people sometimes observe a sweet taste after sucking on a starch-containing food for an extended period of time. Amylase is found naturally in human saliva and the pancreas. However, it is also present in some of the common plant foods consumed by humans. This...
