Answer:
LTI system is stable if Impulse response is finite.
so the correct answer is "b"
(b) h2(t) = e-r cos(2t)u(t)
Answer:
A) attractive force between ions = 5.09x10^-19 N of attractive force
B) there will be no repulsion since both ions have opposite charges.

Answer:
A famous example of concurrent engineering is the development of the Boeing 777 commercial aircraft. The aircraft was designed and built by geographically distributed companies that worked entirely on a common product database of C A TIA without building physical mock-ups but with digital product definitions.
Answer:
w ( mass flow rate of air ) = 3.16 kg/s
Explanation:
<u>Determine the mass flow rate of air </u>
mass flow rate of water = 1.5 kg/s
Height at which air enters the cooling tower = 1m
velocity of air entering at 1 m = 20 m/s
Height at which air leaves the cooling tower = 7 m
attached below is a detailed solution of the problem
