Determine the kinetic energy of a 10 Kg roller coaster car that is moving with a speed of 2m/s.
Answers
In this question all required information's are already provided. Based on these details the answer to the question can be easily determined. Let us now write down all the information's that are already given.
Mass of the roller coaster = 1000 kg
Velocity of the roller coaster = 20.0 m/s
We know the formula for finding the kinetic energy is
Kinetic energy = 0.5 * mass * (velocity) ^2
= 0.5 * 1000 * (20)^2
= 0.5 * 1000 * 400
= 200000 Joules
So the Kinetic energy of the roller coaster is 200000 joules.

A ray of light passes through the air and enters the water inside a metal container. The light ray bends as it crosses the boundary between air and water. Once it hits the bottom of the container, the ray gets reflected. The reflected ray passes back through the water and enters the air without bending. In this example, the ray of light is both reflected and refracted.

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.

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

The work input = _____.
F i ÷ d i
F o ÷ d o
F o × d o
F i × d i
Answers
The work input = Fi × di
How to solve for work input?To solve for work input, you need to know the force acting on an object and the distance it moves in the direction of the force. Work input is defined as the product of force and distance, given by the formula:
Work Input = Force × Distance × cosθ
Where θ is the angle between the force vector and the direction of motion. If the force is applied in the direction of motion, then θ = 0 and cosθ = 1, so the formula simplifies to:
Work Input = Force × Distance
For example, if you are pushing a box with a force of 50 newtons over a distance of 10 meters, the work input would be:
Work Input = 50 N × 10 m × cos(0°) = 500 Joules

(1.) Consider the equation: 4Fe + 3O2 yields 2Fe2O3
- What is the theoretical yield of Fe2O3 when 12.0g of iron rusts?
- If 14.21 g of Iron (III) oxide is actually produced what is the percent yield ?
(2.) what is the molarity of a 126.81 L solution that contains 5.1 moles of KCl ?
Answers
1a. The theoretical yield of Fe₂O₃ obtained is 17.14 g
1b. The percentage yield of Fe₂O₃ obtained is 82.9%
2. The molarity of the KCl solution is 0.04 M
1a. How to determine the theoretical yield of Fe₂O₃Balanced equation
4Fe + 3O₂ —> 2Fe₂O₃
Molar mass of Fe = 56 g/mol
Mass of Fe from the balanced equation = 4 × 56 = 224 g
Molar mass of Fe₂O₃ = (56×2) + (16×3) = 160 g/mol
Mass of Fe₂O₃ from the balanced equation = 2 × 160 = 320 g
SUMMARY
From the balanced equation above,
224 g of Fe reacted to produce 320 g of Fe₂O₃
Therefore,
12 g of Fe will react to produce = (12 × 320) / 224 = 17.14 g of Fe₂O₃
Thus, the theoretical yield of Fe₂O₃ is 17.14 g
1b. How to determine the percentage yield Actual yield of Fe₂O₃ = 14.21 gTheoretical yield of Fe₂O₃ = 17.14 gPercentage yield of Fe₂O₃ =?Percentage yield = (Actual / Theoretical) × 100
Percentage yield of Fe₂O₃ = (14.21 / 17.14) ×100
Percentage yield of Fe₂O₃ = 82.9%

Answer:
The Mars Science Laboratory and its rover, Curiosity, were launched from Earth on November 26, 2011. As of May 15, 2021, Curiosity has been on the planet Mars for 3119 sols (3204 total days; 8 years, 282 days) since landing on August 5, 2012. (See Current status.)Prelaunch (2004–2011)
Cruise stage is tested in 2010.[1]
In April 2004, the United States National Aeronautics and Space Administration (NASA) called for scientific experiments and instruments proposals for the Mars Science Laboratory and rover mission.[2] Launch was proposed for September 2009.[3][4] By December 14, 2004, eight proposals were selected, including instruments from Russia and Spain.[2][4]
Testing of components also began in late 2004, including Aerojet's monopropellant engine with the ability to throttle from 15 to 100 percent thrust with a fixed propellant inlet pressure.[2] By November 2008 most hardware and software development was complete, and testing continued.[5] At this point, cost overruns were approximately $400 million.[6] In December 2008, lift-off was delayed to November 2011 due to insufficient time for testing and integration.[7][8][9]
Between March 23–29, 2009, the general public ranked nine finalist rover names (Adventure, Amelia, Journey, Perception, Pursuit, Sunrise, Vision, Wonder, and Curiosity)[10] through a public poll on the NASA website.[11] On May 27, 2009, the winning name was announced to be Curiosity.
