State two main consumers of electricity transmitted at low frequency Calculate the primary voltage of a transformer if the primary winding is 50 turns and the secondary winding is 150 turns with 450 volts.
Answers
Answer:
1) a. Customers requiring AC electric power transmission for powering remote devices which may include a subsea transmission system where power is distributed to subsea devices
b. Customers that utilize commutator-type motors
2) The primary voltage is 150 volts
Explanation:
The parameters given are;
Number of primary winding, \(N_p\) = 50 turns
Number of secondary winding, \(N_s\) = 150 turns
Voltage in secondary winding, \(V_s\) = 450 volts
Voltage in primary winding = \(V_p\)
The relation between \(N_p\), \(N_s\), \(V_s\) and \(V_p\) is as follows;
\(\dfrac{V_p}{V_s} = \dfrac{N_p}{N_s}\)
Which gives;
\(V_p = \dfrac{N_p \times V_s}{N_s}\)
From which we have;
\(V_p = \dfrac{50\times 450}{150} = 150 \ volts\)
The primary voltage = 150 volts.

Answers
B. One variable should change, and the others should be kept the same.
Explaination:
In a well-designed experiment, researchers typically manipulate or change one specific variable, known as the independent variable, to observe its effect on another variable, known as the dependent variable. The independent variable is the factor that the researcher deliberately varies to test its influence on the dependent variable, which is the factor that the researcher measures or observes for changes. All other factors that could influence the results are kept constant or controlled, known as controlled variables, to isolate the impact of the independent variable on the dependent variable. This helps ensure that any observed changes in the dependent variable can be confidently attributed to the manipulation of the independent variable.
In an experiment, the factors that can change are called variables. The correct answer is B. One variable should change and the others should be kept the same.
When conducting an experiment, it is important to have a controlled environment. This means that all variables, except for the one being tested, should be kept constant. By changing only one variable, scientists can observe the effect that it has on the outcome of the experiment.
For example, let's say you want to investigate the effect of temperature on the rate of plant growth. In this experiment, you would keep all other factors, such as light, water, and soil type, constant. You would then vary the temperature and measure the growth of the plants. By changing only the temperature, you can determine its specific impact on the rate of plant growth.
By controlling the variables in an experiment, scientists can confidently attribute any changes observed in the outcome to the specific variable being tested. This allows for accurate and reliable results.
Therefore, in an experiment, one variable should change while the others are kept the same (option B).
B. One variable should change, and the others should be kept the same. In an experiment, it is important to only change one variable at a time while keeping all other variables constant. This allows researchers to observe the specific effects of that one variable on the results. Changing multiple variables at once can make it difficult to determine which variable is responsible for any observed changes.
In an experiment, variables are the factors that can potentially affect the outcome or results. The answer B states that in an experiment, one variable should change, while the others should be kept the same.
This is important because in order to understand the relationship between variables, it's necessary to isolate the effects of one specific variable at a time. By changing only one variable, called the independent variable, while keeping all other variables constant, we can observe how that one variable affects the outcome, known as the dependent variable.
For example, let's say you are conducting an experiment to investigate the effect of temperature on the rate of plant growth. You would keep factors such as soil type, amount of water, and light intensity constant. The only variable you would change is the temperature. By varying the temperature and observing the growth of the plants, you can determine the impact of temperature on plant growth.
This approach helps to establish a cause-and-effect relationship between the independent variable and the dependent variable. If multiple variables were changed simultaneously, it would be difficult to determine which variable was responsible for the observed changes in the outcome. Therefore, changing one variable at a time and keeping others constant allows for a clearer understanding of the relationship between variables in an experiment.

They are geographic factors capable of modifying the climate, as they influence the climatic elements. The main ones are: altitude, latitude, continentality, maritime area, air masses, maritime currents, relief, vegetation and urbanization.

Materials with lower viscosity and density will be more suitable for transporting fluids with high flow rates.Cost: The cost of the material used for building pipes in a pipeline is an important consideration. Engineers need to choose a material that is both durable and cost-effective, while still being able to meet the flow and pressure requirements.Answer:

Securely glue or tape the piece of cardboard onto the box.
Make lengthwise guides to keep the ball on the ramp. Connect three straws end to end. To connect them, squeeze the end of one straw and insert it into the end of another straw. Tape the guide along one side of the ramp. Make a second guide using three more straws. Tape it along the other side of the ramp. The space between the guides should be a little wider than the width of the ball.
Set up the ramp. The top of the ramp should be 12 inches off the floor. Place the box (vehicle 1) at the base of the ramp—the box should be touching the end of the ramp. The side with the added cardboard piece should face the ramp. Orient the box so it’s wider than it is high.
Let the ball roll down the ramp and hit the box. The box should fall over and move across the floor.

What is force in collision?Collisions between two objects naturally fall under Newton's third law of motion. When two objects collide, forces of equal magnitude and opposite direction are applied to each object.
Such pressures frequently result in one thing gaining momentum and gaining speed while the other object slows down (lose momentum). Newton's third law states that the forces acting on the two objects are of equal strength.
The objects' accelerations may not be equal in magnitude even though the forces acting on them are opposite in direction and of equal magnitude.
