A point charge of 1 nC carries over two paths in an electric field of = 2 + V / m. The first path starts at A (2, 30º, 0) and ends at point C (4, -90 º, 0) through the point B (2, -90 º, 0). The second path starts from the point A (2, 30º, 0) and ends at the point C (4, -90º, 0) through the point D (4, 30º, 0). Calculate the energy consumed while the load is transported separately on both paths.

The higher the astm grain-size number, the coarser the grain is. a)-true b)-false

Inspection for bearing condition will include: (clo4) a)-color b)-smell c)-size d)-none of the above

Afoot bridge is made as a simple deck, 4 m long, with a cross section 2 m (wide) and 20 cm thick, and made of wood. the deck is supported at the two ends. the maximum load allowable on the bridge is 10 tons, provided it is uniformly distributed on the deck. to sense this load, a strain gauge is placed at the center of the bridge and its resistance is monitored. if the sensor has a nominal resistance of 350 s2 and a gauge factor of 3.6, what is the reading of the strain gauge at maximum load? the modulus of elasticity for the wood used in the construction is 10 gpa.
