What modern tools do these early tools resemble? 1.> Small sharp tipped tool which is made of bone. 2.> Roughly the size of arrowhead, the 1.5 inch tip of this hand held tool is made of flint, a very hard rock. the wooden
Two identical thin wires are oriented along the x and y axes. With current on x plane going North. Current on y plane going West.Both carry the same current I, and there is no electrical contact between the wires. The points A, B,
A sign with a mass of (24) kg is hanging in two wires both making an angle of (52) degrees with the vertical. Find the tension in one of the wires. Give your answer in newtons (N) and with 3 significant figures.
Q.1. Two wires each of length 40 m and diameter 2.6 mm, are connected in series. A potential difference of 50 V is applied between the ends of the composite wire. The resistances the wires are 0.13 Ω and 0.75 Ω,
