During load shedding

a.  system voltage is reduced

b.  some loads are switch off

c.  system power factor is changed

d.  system frequency is reduced

Which of the following is not a lean inventory​ tactic?

A. Use a push system to move inventory

B. Reduce lot size

C. Use group technology

D. Reduce setup time

A bandpass filter passes signals with frequencies that are within a certain range.In this filter the ratio of the magnitudes of the voltages is given by:
RV=V0/Vi=wRC/sqrt(1-w^2LC)^2+(wRC)^2 where w is the frequency of the input signal.Given R=1000ohm,L=11mH and C=8µF,determine the frequency range that corresponds to RV>=0.87.
Using MATLAB:
a) First plot the graph
b)Use matlab to construct a script for the Bisection method and Newton's method to find one of the possible roots.

Among the following statements, which statement finds the logical consequence of the second law of thermodynamics?

1. This law states that the entropy of an isolated system always increases or equal to zero but can never decrease

2. This law is a relationship between the energy and the internal energy of a system

3. This law states that entropy attains a constant value at absolute zero temperature

4. This law states enthalpy of a closed system is a point function
