A heater has a resistance of 15 Ω. It operates on 120 V. What thermal energy is supplied by the heater in 2 minutes?

Answers

Answer 1

Answer:

E = 115.2 kJ

Explanation:

Given that,

Resistance, R = 15 ohms

Voltage, V = 120 V

We need to find the energy supplies by the heater in 2 minutes or 120 s.

The formula for the thermal energy supplies is given by :

[tex]E=I^2Rt[/tex]

We know that, V = IR

So,

[tex]E=\dfrac{V^2t}{R}\\\\E=\dfrac{(120)^2\times 120}{15}\\\\E=115200\ J\\\\E=115.2\ kJ[/tex]

So, 115.2 kJ of energy is supplied.

Explanation:

The wind is an actual form of solar energy. winds are caused by the heating of the atmosphere by the sun, the rotation of the earth, and the earth's surface irregularities. The wind is capture in a wind turbine which provides a renewable energy source, the wind makes the rotor spin, as the rotor spins the movement of the blades drives a generator that creates energy, also known as wind power. The average wind efficiency of turbines is between 35-45%.

How do engineers deal with liquefaction when building a very tall building?

Answers

Answer:

Engineers can use a variety of techniques to prevent or mitigate the effects of liquefaction when building a very tall building. Liquefaction is a phenomenon that occurs when soil loses its strength and stiffness due to increased pore water pressure. This can cause the ground to become unstable, potentially leading to significant damage to buildings and other structures. To prevent liquefaction, engineers may use a combination of techniques, including:

Deep foundations: By building the foundations of a building deep into the ground, engineers can reduce the effects of liquefaction by increasing the weight and stiffness of the soil. This can help to keep the building stable even if the ground around it becomes unstable.
Vibration monitoring: Engineers can use sensors and other monitoring equipment to detect and measure vibrations in the ground. This can help them to identify areas where liquefaction is likely to occur, allowing them to take corrective action before it becomes a problem.
Soil improvement: In some cases, engineers may be able to improve the soil by adding chemicals or other materials that increase its strength and stiffness. This can help to prevent liquefaction and make the ground more stable for building.
Flexible design: By designing buildings with a certain amount of flexibility, engineers can reduce the effects of liquefaction on the structure. For example, they may use flexible connections between the foundation and the building itself, or incorporate materials that can withstand movements caused by liquefaction.

Calculate the amount of current flowing through a 75-watt light bulb that is connected to a 120-volt circuit in your home.

Answers

Answer:

I = 0.625 A

Explanation:

Given that,

Power of the light bulb, P = 75 W

Voltage of the circuit, V = 120 V

We need to find the current flowing through it. We know that, Power is given by :

[tex]P=V\times I[/tex]

I is the electric current

[tex]I=\dfrac{P}{V}\\\\I=\dfrac{75\ W}{120\ V}\\\\I=0.625\ A[/tex]

So, the current is 0.625 A.

True

Answers

Primary power is the electrical supply from the power company. The given statement is True.

How do main and secondary powers differ?

Primary distribution lines, often known as primaries, are those located on the high voltage side of the distribution transformer. Secondary distribution lines, or secondaries, are those found on the low-voltage side of the distribution transformer. Primary energy (PE) is a type of energy that can be found in nature that hasn't undergone any artificially designed conversion procedures. It is the energy that is present in unprocessed fuels and other energy sources, such as trash, that are introduced into a system.

Renewable or nonrenewable sources can be used for primary energy. Primary energy sources come in a variety of shapes and sizes, and they can be either nuclear, fossil (such as coal, oil, and natural gas), or renewable (such as wind, solar, geothermal, and hydropower).
