Answers
Answer:
Explanation: COMPOST BIN
WHAT IS A COMPOST BIN?
A compost bin is a container into which you place organic waste to turn into compost (organic material) over time.
Most compost bins are designed to hasten the decomposition of organic matter through proper aeration and moisture retention. With the proper combination of air and moisture, ideal conditions are produced for the activity of aerobic organisms responsible for the high temperatures that transform the organic materials into compost
Read on to find out how to start a compost bin, DIY compost bin ideas, and more tips for beginners.
The decomposition process will eventually take place over time in a compost "pile" or "heap," even without any housing to contain the matter. However, a compost bin is worth it because it helps speed up decomposition and keeps the area neat. Some bins are continuous, meaning you can keep adding waste to them, while others create batches of compost with a set mix of ingredients you add all at once. Depending on the style of compost bin you choose, bins can also have the advantage of making it harder for rats to get at your compost. This is true of the tumbler type, for example.
CHOOSING THE RIGHT BIN
Select the right bin for your composting needs. You can make an inexpensive compost container out of almost any container or material. Some ideas include:
Plastic storage container
Plastic bucket
Trash cans
Straw bales
Lumber
Branches harvested from the woods
Stone
Cinder blocks
Wire fencing
Ceramic (also popular for a kitchen countertop compost bin)
The best bin, however, is one you can easily turn or rotate consistently to control odors and make sure all the materials decompose. This is especially important for aerobic composting (more information below). A tumbler composting bin is pricey, but you can DIY one from barrels and sawhorses. You can turn compost with a rake or shovel in a non-rotating bin, it just takes more labor to do so.

The strength of the electric field can be estimated as force per electric charge, whereas the strength of a magnetic field depends on the force of electrons and velocity.
Whta is a magnetic field?A magnetic field can be defined as magnetic work exerted on electric charges that are in motion (movement).
Conversely, an electric field is an area where an electric current is applied and electron force can be estimated per Volts per Meter.
In conclusion, the strength of the electric field can be estimated as force per electric charge, whereas the strength of a magnetic field depends on the force of electrons and velocity.

My question:
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.

Here, I hated PE too. Write down calories, and make up lame exercises to "burn them off" like running or swimming or dancing. Do it appropriately, sometimes you can't allways burn it off, like if you gained 100 calories and only burned 80. It's fine.
A rule of thumb is that about 100 calories per mile are burned for a 180-pound person and 65 calories per mile are burned for a 120-pound person. A 150-pound person will burn roughly 400 calories during an hour-long swim at a moderate pace and 700 at a vigorous one. The average person will burn 300-800 calories per hour dancing.
In this activity, you modeled the Sun–Earth–Moon system. If you removed one object from this system model, would the model still explain the changes to the Moon’s appearance?

waxing crescentwaxing gibbouswaning crescentwaning gibbousIn this activity, if you modeled the Sun–Earth–Moon system and you remove one object from this system model, would the model still explain the changes to the Moon’s appearance?
The answer is capital NO.
The reason is simply because the moon appearance is relatively base on the positioning of Sun - Earth - Moon relationship. That is, the moon appearances of waxing crescent, waxing gibbous, waning crescent and waning gibbous, all depend on the position of the Sun, Moon and the earth.
Therefore, If you removed one object from this system model, the model cannot explain the changes to the Moon’s appearance again.

What is the Total Magnitude of the combined Drone + Wind vectors?:
What is the Total Angle of the combined Drone + Wind vectors?:
Answers
The x and y component of the drone vector are 21.21 mph and 21.21 mph respectively.
The x and y component of the wind vector are -7.5 mph and -12.99 mph respectively.
The total x-component of the combined Drone + Wind vectors is 13.71 mph.
The total y-component of the combined Drone + Wind vectors is 8.22 mph.
The magnitude of the total vector is 15.99 mph.
The total angle of the combined Drone + Wind vectors is 31⁰.
What is the x and y component of the drone vector?The x and y component of the drone vector is calculated as follows;
Vx = 30 mph x cos (45)
Vx = 21.21 mph
Vy = 30 mph x sin (45)
Vy = 21.21 mph
The x and y component of the wind vector is calculated as follows;
θ = 240⁰ - 180⁰ = 60⁰
Vx = -15 mph x cos (60)
Vx = -7.5 mph
Vy = -15 mph x sin (60)
Vy = -12.99 mph
The total x-component of the combined Drone + Wind vectors is calculated as;
Vx_tot = 21.21 mph -7.5 mph = 13.71 mph
The total y-component of the combined Drone + Wind vectors is calculated as;
Vy_tot = 21.21 mph - 12.99 mph = 8.22 mph
The magnitude of the total vector is calculated as;
V = √ (13.71² + 8.22²)
V = 15.99 mph
The direction of the combined vector is calculated as;
θ = tan⁻¹ (Vy_tot/Vx_tot)
θ = tan⁻¹ (8.22/13.71)
θ = 30.95⁰
θ ≈ 31⁰
