As an analogy of a circuit with resistance, think of an obstacle race . Which parts of a circuit do the obstacles represent? which part of the circuit do the people respresent?
Answers
In an analogy of a circuit with a resistance to an obstacle race, we can consider various elements of the race as representative of different components of the circuit.Obstacles, Track or Route, Participants, Start and Finish Line.
Obstacles: The obstacles in the race represent the resistors in a circuit. Just as resistors impede the flow of current in a circuit, obstacles in the race create hurdles that slow down the participants. The difficulty or magnitude of the obstacles can be equated to the resistance value of the resistors in a circuit.
Track or Route: The race track or route itself can be seen as the conductive path in a circuit. It provides a pathway for the participants to move and complete the race. Similarly, the conductive path in a circuit allows the flow of current from the power source to the load.
Participants: The people participating in the race represent the flow of electrons in a circuit. Just as the participants move through the obstacles in the race, electrons move through the resistors in a circuit. The rate at which participants complete the race can be compared to the current flowing through the circuit.
Start and Finish Line: The start and finish line of the race correspond to the terminals of a circuit. The start line represents the positive terminal, where the participants begin their journey, and the finish line represents the negative terminal, where the race concludes.

Answer: As an analogy of a circuit with resistance, the obstacles in an obstacle race represent the resistance in a circuit. The parts of the circuit that the obstacles represent are the resistors. The people in the obstacle race represent the current in a circuit. The current is the flow of charged particles (such as electrons) in a circuit. In an obstacle race, the people are moving through the obstacles, just as the charged particles are moving through the resistors in a circuit. The obstacles slow down the people, just as the resistors slow down the flow of charged particles in a circuit.

O B. 7,840,000 J
O C. 2J
O D. 39,200 J
Answers
Answer:
39,200J
Explanation:
just took the test
The meteor's potential energy if it has a mass of 10kg at an altitude of 400 m will be 39200 J
What is potential energy ?Potential Energy that depend upon the relative position of various parts of system . It is an energy possessed by an object by virtue of its position or configuration.
mass(m) = 10kg
g (acceleration due to gravity) = 9.8m/s^2
altitude(height (h)) = 400m
Meteor's Potential energy = m * g * h
= 10 * 9.8 * 400 = 39200 J
correct option will be a) 39200 J

Why is it important to track our carbon and ecological footprint?
Answers
Answer: I got you Fam
Explanation:
it is one competing demand for biologically productive space
Answer:
The carbon footprint is a very important means to understand the impact of a person's behavior on global warming. This is why someone who effectively wants to contribute to stopping global warming, at least on an individual scale, needs to measure and keep track of their personal carbon footprint.
Why is it important to track your ecological footprint?
The Ecological Footprint is a simple metric. It is also uniquely comprehensive. Not only does it measure humanity's demand on our planet's ecosystems, but it is also key to understanding the inter-related pressures of climate change on the natural ecosystems on which humanity depends.
Why is knowing your carbon ecological footprint important?
Knowing your personal or organisational carbon footprint is useful for the following reasons: it enables you to identify and reduce GG emissions, it allows corporations to publish their environmental performance statistics, it can be used as information to raise awareness of environmental costs.

Scientists have discovered convection currents inside Earth. Explain how these convection currents move and what layer(s) they occur in.
Answers
Answer:
It occurs in the mantle. As the core heats up the bottom of the mantle, the particles move faster causing the mantle to lose density. That causes it to rise and the rising starts the Convection Currents.
The convection currents occur in the mantle layer of the earth The stiff tectonic plates of the Earth move in response to convection currents in the planet's fluid, molten core.
What are convection currents?Convection currents are fluid motions brought on by temperature or density variations within a substance. Because the particles within a solid are fixed in place, convection currents are only visible in gases and liquids. A straightforward illustration of convection currents is warm air rising toward a home's ceiling or attic.
Differential heating leads to convection currents. Warm, less dense, lighter material rises while cool, more dense, heavier material sinks. Convection currents are patterns of circulation that are produced by this movement in the Earth's mantle, oceans, and atmosphere.
It takes place in the mantle. The particles travel more quickly toward the bottom of the mantle as the core heats it, causing the mantle to lose density. It rises as a result of that, and the rising causes the Convection Currents to begin.

What is energy?Energy is the ability or capability to do tasks, such as the ability to move an item (of a certain mass) by exerting force. Energy can exist in many different forms, including electrical, mechanical, chemical, thermal, or nuclear, and it can change its form.
potential energy = mgh = 20*9.8*100 = 19.6 KJ
At the lowest point all potential energy is converted into kinetic energy so kinetic energy = 19.6 KJ.
