cogeneration plants are different from regular commercial generating stations because the heat, after it generates electricity,

is later sold to a(n)_____?
Physics

statuscvo [17]4 years ago
5 0

Answer:

Central heating plant or manufacturer.

Explanation:

Co generation plants are useful in the sense that they do not let the thermal energy wasted for heating, they utilize it. They use that heat to drive the steam or gas turbine- powered generators. However the regular commercial generating stations do not do that.

A certain organ pipe, open at both ends, produces a fundamental frequency of 288 Hz in air. Part A If the pipe is filled with he
alina1380 [7]

Answer:

773.25 Hz

Explanation:

Concept : In an open organ pipe in fundamental mode of vibration

wave length of wave λ = 2L

where L  is length of  the pipe

frequency   = velocity of sound / λ

Given values: fundamental frequency = 288 Hz

fluid is air. velocity of sound = 340 m/s

⇒ 288 = 340/2L

⇒L = 59.02 cm

The point to be noted is if the pipe is filled with helium initially at the same temperature, there would be change in the sound velocity .Then,  frequency of note produced will also be changed .

We know that velocity of sound is inversely proportional to  square root of molar mass of gas

velocity of sound in air / velocity of sound in helium = Square root of (Molar mass of Helium/ molar mass of air)

\frac{V_a}{V_{He}} = \sqrt{\frac{4}{28.8} } \\\frac{340}{V_{He}} =0.3725\\V_{He} =912.5 m/s

Now, frequency  = velocity of sound / λ

= 912.75 / (2 x 0.5902)

= 773.25 Hz

Two electrically opposite charges are separated by a fixed distance. Which action will provide the greatest increase in the forc
Alex73 [517]

Explanation:

The electric force between charges is given by the formula as follows :

F=\dfrac{kq_1q_2}{r^2}

k is electrostatic constant

r is distance between charges

Here, charges are equal and opposite. So,

F=\dfrac{kq^2}{r^2}

It is clear the force is inversely proportional to the distance between charges and directly proportional to the product of charges. So, greatest force will be providing by :

  • Increasing the magnitude of charges
  • Decreasing the distance between charges.

How do you balance this equation Mg+ O2= MgO
Anuta_ua [19.1K]

Answer:

2 Mg(s) + O2(g) → 2 MgO(s)

As magnesium (Mg) has a valency of +2, and oxygen (O) has a valency of -2, the ratio would be 1:1, and magnesium oxide would be represented as MgO. It is insoluble in water, hence it has the subscript as a solid, represented by (s). In order to use up the diatomic oxygen (O2), there needs to be two moles of magnesium (2Mg) on the reactant side. This would produce 2 moles of MgO on the product side.

12. An astronaut whose mass is 70 kg on Earth's surface 12 poi
Vadim26 [7]

Her mass is still 70 kg

Explanation:

The mass of an object is an intrinsec property of the object that gives a measure of the "amount of matter" inside the object.

Being an intrinsec property, it depends only on the object itself, not on its location: therefore, the mass of an object is always the same in different locations. Therefore, the mass of the astronaut in the spacecraft is still the same as if she was on the earth, 70 kg.

On the contrary, the weight of an object is the force of gravity acting on the object, and it is given by

F=mg

where

m is the mass

g is the acceleration of gravity

While m is always the same, the value of g changes based on the location: therefore, the weight of an object changes  depending on the location.
