Why are the more strict tools for assessing green products those that demand second- or third-party verification? The assessment process is more elaborate.
The assessment process takes longer.
The assessment process is more independent,
The assessment process is more adaptable.

During a steady flow process, the change of energy with respect to time is zero. a)- true b)- false

Burgers vector is generally parallel to the dislocation line. a)-true b)-false

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.
