C(iii) : versus the parameter C
The parameter C is centered in a nonlinear equation, therefore the standard locus will not apply hence when you use a polynomial solver the roots gotten would be plotted against C
Answer:
The Poisson's Ratio of the bar is 0.247
Explanation:
The Poisson's ratio is got by using the formula
Lateral strain / longitudinal strain
Lateral strain = elongation / original width (since we are given the change in width as a result of compession)
Lateral strain = 0.15mm / 40 mm =0.00375
Please note that strain is a dimensionless quantity, hence it has no unit.
The Longitudinal strain is the ratio of the elongation to the original length in the longitudinal direction.
Longitudinal strain = 4.1 mm / 270 mm = 0.015185
Hence, the Poisson's ratio of the bar is 0.00375/0.015185 = 0.247
The Poisson's Ratio of the bar is 0.247
Please note also that this quantity also does not have a dimension
Answer:
Three objectives of a tariff are
1) To control trade between countries
2) To protect domestic industries
3) To provide a source of income
Three characteristics of a tariff are;
1) Adequate return
2) Attractive
3) Fairness
Explanation:
A tariff is an import or export tax placed on goods traded between countries, it serves to control the foreign trade between the two countries and to protect or develop local industry
A Tariff is an important source of income to countries
Three characteristics of a tariff are;
1) Adequate return
Proper return from the consumer should be factored in a tariff to account for the alternatives or normal expense pattern
2) Attractive
The tariff should be attractive to encourage consumption of electricity or complimentary goods
3) Fairness
Based on the consumption of related resources brought about by large scale utilization, large consumer tariff should be lower than those that consume less complementary resources.
