Answer:
N = 38546.82 rpm
Explanation:
= 150 mm
= 17671.45 
= 250 mm
= 49087.78
The centrifugal force acting on the flywheel is fiven by
F = M ( 
- 
) x 
------------(1)
Here F = ( -UTS x 
+ UCS x 
)
Since density, 
∴ - = 50 mm
∴ F = 
F = 33618968.38 N --------(2)
Now comparing (1) and (2)
∴ ω = 4036.61
We know
∴ N = 38546.82 rpm
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.
Answer:
D) AND gate.
Explanation:
Given that:
A certain printer requires that all of the following conditions be satisfied before it will send a HIGH to la microprocessor acknowledging that it is ready to print
These conditions are:
1. The printer's electronic circuits must be energized.
2. Paper must be loaded and ready to advance.
3. The printer must be "on line" with the microprocessor.
Now; if these conditions are met the logic gate produces a HIGH output indicating readiness to print.
The objective here is to determine the basic logic gate used in this circuit.
Now;
For NOR gate;
NOR gate gives HIGH only when all the inputs are low. but the question states it that "a HIGH is generated and applied to a 3-input logic gate". This already falsify NOR gate to be the right answer.
For NOT gate.
NOT gate operates with only one input and one output device but here; we are dealing with 3-input logic gate.
Similarly, OR gate gives output as a high if any one of the input signals is high but we need "a HIGH that is generated and applied to a 3-input logic gate".
Finally, AND gate output is HIGH only when all the input signal is HIGH and vice versa, i.e AND gate output is LOW only when all the input signal is LOW. So AND gate satisfies the given criteria that; all the three conditions must be true for the final signal to be HIGH.
