Determine whether each of the following systems are 1. Linear or non-linear 2. Time-invariant or time varying 3. Causal or non-causal 4. BIBO stable or unstable 5. Memory-less or not. Justify each of your answers. (Stating an answer without justification will earn you no credit)a. y[n]= 3x[2n] b. y[n] = n^2x[n+1] c. y[n] = Cos(ωo. n) x[n-5] where ωo is a constant d. y[n] = e^n x[5-n] e. where N is a constant

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.

A5 kg block of fe is dropped into a very large vat of water. the fe and water initial temperatures are 95 and 25 c, respectively. the fe final temperature is 25 c and the water can be treated as a thermal reservoir,. treated as a thermal reservoir take the water to be the system and determine the entropy generation. report vour answer in kj/k.
