Discuss three objectives of Tariff and elaborate on three characteristics of it
Margaret [11]

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.

The dot plot shows the number of cupcakes bought by each person who came to a bake sale.
Maslowich

The true statement about the dot plot is 1 has 4 and 0 dots.

Explanation:

  • after creating a Bar chart 4 is the right answer.
  • The highest among st all the other plots is 1 but 4 shows 3.
  • Taking an average from all the data points 3 comes to the right answer.
  • Median the central Mid-point is 3.
  • Mode also comes to 3.
  • It is skewed on the right due to the 1st one.
  • Skewed shows the data point either increasing or in decreasing.
  • There a to Bi- histograms which has two ups and downs.
  • The true statement has to be as Mean=Median=Mode is 3.

A 3-phase induction motor with 4 poles is connected to a voltage source with an amplitude of 209 Vrms and a frequency of 120 Hz.
Ket [755]

Answer:

<em>T = 25.41 Nm</em>

Explanation:

Calculating Nsync (Synchronous Speed):

Nsync = 120f/P

Nsync = 120 x 120 / 4\\Nsync = 3600 rpm

Wsync = 3600 * 2\pi /180\\Wsync = 377 rad/s

Calculating s (Slip):

s = (Nsync - Nm) / Nsync \\[tex]s = (3600-2464)/3600\\s = 0.3156

Calculating Vth (Thevenin Voltage):

Vth = Vph (Xm / \sqrt{Rs^{2} + (Xs+Xm)^{2}  })\\Vth = 209 (76 / \sqrt{(2.3)^{2} + (1.3 + 76)^{2}  }\\Vth = 205.39 V

Calculating Rth (Thevenin Resistance):

Rth = Rs (Xm/Xs + Xm)^{2} \\Rth = 2.3 (76/1.3 + 76)^{2} \\Rth = 2.22 ohm

Calculating Xth (Thevenin Reactance):

Xth = Xs = 1.3 ohm

Calculating Torque:

T = (3Vth^{2}Rr/s) / (Wsync[(Rth+Rr/s)^{2} + (Xth + Xr)^{2}])\\T = (3*205.39*0.7/0.3156) / 377[(2.22+0.7/0.315)^{2} + (1.3+1.8)^{2}]

T = 280699 / 377 [19.69 + 9.61]

<em>T = 25.41 Nm</em>

The function below takes a single argument: data_list, a list containing a mix of strings and numbers. The function tries to use
pychu [463]

Answer:

def filter_only_certain_strings(data_list):

   new_list = []

   for data in data_list:

       # fix here. change >= to >  

       # because we want to return strings longer than 5 characters in length.

       if type(data) == str and len(data) > 5:

           new_list.append(data)

   return new_list

Explanation:
