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.

can someone create a 2-minute presentation about wind
also i am giving 40 points
no dam links
if you put links i will hack your brainiy account
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%.
Advantages of wind power
- Wind power is cost-effective
- wind creates jobs
- wind enables US industry growth and US competitiveness
-it's a clean fuel source

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

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

Distinguish between the first two steps of an implementation plan: stating the problem and evaluating the problem.
Answer:
The first step of the problem solving process is to identify and define the problem. The second step, which is to analyze the problem, involves gathering information, sorting through relevant and irrelevant information, and evaluating the source of the problem by asking the Five W's: who, what, where, when, and why.

Which of the following tools utilizes a bubble of air floating in liquid?
A. level
B. sliding T bevel
C. tri-square
D. square
Answer:
Option A
A level tool utilizes a bubble of air floating in liquid
Explanation:
A level tool (spirit level, bubble level) utilizes a bubble of air floating in liquid. This is a mechanism to check whether the surface is horizontal (level) or vertical (plumb). The air bubble must always be at the center with in the two level indication line marks.
Hence, option A is the right answer
Primary power is the electrical supply from the power company.
False
True
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).

Wind is the flow of gases on a large scale. On the surface of the Earth, wind consists of the bulk movement of air. Winds are commonly classified by their spatial scale, their speed, the types of forces that cause them, the regions in which they occur, and their effect. Wind is the flow of gases, here on Earth it refers to the movement of air.
It is caused by differences in air pressure. ...
Short bursts of wind moving at high speeds are known as gusts.
Depending on their strength, winds can be known as a breeze, gale, storm or hurricane.
why does high resistance not affect a parallel circuit
Answer:
Because the equivalent or the total resistance is lower comparatively.
Explanation:
It is because in parallel circuit, the equivalent resistance or the total resistance is lower comparatively and hence more current flow through the circuit.
Basically, the same resistors connected in series have high values as compared to the scenario when these resistors are connected in parallel.
