Answers
Answer: write it out in number form. It should ge easier from there
The acceleration of the skier will be 6.8 m/s².
The following information can be gotten from the question:
Angle of inclination = 44°.Acceleration due to gravity = 9.80 m/s²Therefore, the acceleration of the skier will be:
= g × sinθ
= 9.8 × sin44°
= 6.8 m/s²
Therefore, the acceleration of the skier will be 6.8 m/s².

Plants give off oxygen as part of photosynthesis. Explain the impact of this process on humans.
Answers
Answer:
Humans breathe in the oxygen that the plants produce, in return we breathe out carbon dioxide which is what plants breathe in so in total, we both are helping each other.
The process of photosynthesis is helpful for humans because it involves production of oxygen, essential for human lives.
The given problem is based on the process of photosynthesis and the effect of photosynthesis on humans.
The photosynthesis is the process by which the green plants and other organisms utilize the sunlight to prepare nutrients from carbon dioxide and water.Photosynthesis in plants involve the green pigment known as Chlorophyll, which is responsible for the production of oxygen into the atmosphere.And humans breathe in the oxygen that the plants produce, in return we breathe out carbon dioxide which is what plants breathe in so in total, we both are helping each other.Thus, we can conclude that the process of photosynthesis is helpful for humans because it involves production of oxygen, essential for human lives.

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.

Use the data in the table to explain how you could determine the volume of the block.
Answers
To find the volume of the block, subtract the initial water volume from the final water volume, convert the change in water volume to cubic centimeters, and consider it as the volume of the block.
To find the volume of the block using the measurements provided.
1. Calculate the change in water volume:
The initial water volume is given as 62.3 mL, and the final water volume is given as 89.5 mL. To determine the change in water volume, we subtract the initial volume from the final volume: 89.5 mL - 62.3 mL = 27.2 mL. This value represents the increase in water volume caused by placing the block in the graduated cylinder.
2. Convert the change in water volume to cubic centimeters:
Since 1 mL is equivalent to 1 cubic centimeter (cc), we can directly convert the change in water volume from milliliters to cubic centimeters. In this case, the change in water volume is 27.2 mL, which is also equal to 27.2 cc.
3. Determine the volume of the block:
When the block is placed in the graduated cylinder, it displaces some amount of water, resulting in an increase in water volume. By measuring this increase in volume, we can determine the volume of the block itself. In this case, the change in water volume of 27.2 cc represents the volume of the block.
By following these steps, we can find the volume of the block based on the provided measurements.
Therefore, By deducting the initial water volume from the final water volume and converting the difference in water volume to cubic centimeters, the block's volume can be calculated. the volume of the block is 27.2 cc.

A rock is thrown straight up from the surface of the Earth. Which one of the following statements describes the energy

a) The total energy of the rock increases.
b) The kinetic energy increases and the potential energy decreases.
c) Both the kinetic energy and the potential energy of the rock remain the same.
d) The kinetic energy decreases and the potential energy increases.
e) Both the potential energy and the total energy of the rock increase.
Answers
Answer: d
Explanation:
Uuhhh I’m not good at explanations...
The kinetic energy decreases while the potential energy increases.
Option d is the answer because as soon as this ball gets thrown from the surface of the earth kinetic energy would be at its greatest.
we have
\(k=\frac{1}{2} mv^{2}\)
The velocity is going to be minimized. As the ball is going up its velocity would be falling or decreasing due to gravity. \(k=\frac{1}{2} mv^{2}\) would then have a smaller value. So kinetic energy is reducing/decreasing.
We have potential energy as u = m*g*h = 0. This is because the height is 0 as the ball is released. But as the ball goes up, the height would start to increase so the potential energy increases.
In conclusion as the ball is thrown straight from the earth, kinetic energy decreases and potential energy increases.

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
