Come up with your own team sports game and make your own rules and regulation.
Answers
SO my sports name would be called " Basvollball" It's where you have to hit in a volleyball into a basketball hoop, of course, the time is the same as football with increments of 5 minutes for junior high and 7 minutes for high school with halftime. Also, the ball can never touch the ground and if the ball ever hits the floor its the other's team ball. To decide which team gets the ball, a coin flip will decide it. For the point system, it depends on how far the ball is hit from so it's like basketball from 3 pointers to 2 points inside the line. If the team ever reaches 30 points without the other team scoring, the team who's winning will automatically win after the time runs out in that period or quarter. You can use every body part, as long as, the ball doesn't touch the floor, and you can only use your body to push someone, no pushing with hands or arms. You can play this sport indoors or outside whether the team has a field available. There's also a maximum of 14 players on the field, so 7 players on each team.

1. A particular lever is 90.0% efficient. If 50.0 J of work are done on the lever, then how much work does the lever do on its load? 2.The mechanical advantage of a pulley system is 4.00. Using this pulley system, how much force do you need to exert to lift a 500.0 N box?
Answers
Answer:
Explanation:
Using the efficiency formula;
Efficiency = Work done by the machine (output)/work done on the machine (input) ×100%
Efficiency =w/50 ×100
90 = 100w/50
Cross multiply
90×50 = 100W
4500 = 100W
W = 4500/100
W = 45Joules
Hence the lever does 45Joules of work on its load
2) Mechanical Advantage= Load/Effort
Given
MA = 4
Load = 500N
4 = 500/Effort
Effort = 500/4
Effort =125N
Hence the effort required to lift the load is 125N
1. The work done by the lever on its load is 45 J
2. The force needed to exert to lift the load is 125 N.
1. Determination of the work done by the lever on the load.
Work Input = 50 J
Efficiency = 90%
Work Output =?[tex]efficiency \: = \frac{work \: output}{work \: input} \times 100 \\ \\ 90\% = \frac{work \: output}{50} \\ \\ cross \: multiply \\ \\ work \: output \: = 90\% \: \times 50 \\ \\ work \: output = 0.9 \: \times 50[/tex]
Work Output = 45 JTherefore, the work done by the lever on the load is 45 J
2. Determination of the force needed to lift the load
Mechanical advantage (MA) = 4
Load (L) = 500 N
Effort (E) = ?[tex]mechanical \: advantage \: = \frac{load}{effot} \\ \\ 4 \: = \frac{500}{effort} \\ \\ cross \: multiply \\ \\ 4 \: \times effort \: = 500 \\ \\ divide \: both \: side \: by \: 4 \\ \\ effort \: = \frac{500}{4} \\ [/tex]
Effort = 125 NTherefore, the force needed to lift the load is 125 N

How much does a 200 kg car weigh?
Answers
Answer:
42,000 lbs
Explanation:
100 kg is 210 lbs.
200 x 210 lbs =
42,000 lbs
The weight of the car is product of its mass and acceleration due to gravity of earth. Hence, the weight of the 200 kg car is 1960 N.
What is acceleration due to gravity ?The gravitational force of an object is the force by which attracts other objects into its center of mass. Earth attracts every objects into its center and that is why we are all standing on the ground.
The weight we experience on earth is due to this gravitational force and it decreases when we move far from earth. The acceleration due to gravity is the acceleration by which an object accelerates downwards due to earth's gravity (g).
Weight of an object = mass × g
g for earth = 9.8 m/s²
mass of the car = 200 Kg.
then, weight = 200 kg × 9.8 m/s² = 1960 N.
Therefore, the weight of the car is 1960 N.

This is a lab for science can you help with punctuation errors? Also where it says figures I have pictures :) (I am in 7th grade btw so no hate)
Leaf lab
Purpose: Find out if the leaf area of a given tree is bigger on the North or the Southside. Learn more advanced statistical analysis.
Research: To find the area of an irregular shape it’s whole + part ½ which is whole plus part divided by 2. The shape of the leaf will be traced. They are affected by the Earth's tilt and the sun because we are in the North Hemisphere.
Figure 1 is an example of the Earth’s tilt and how the sun gives a certain amount of heat to different parts of the Earth.
The south gets more sun it’s because the leaves burn while the north leaves get less sun. The north leaves are thinner but bigger in area than the leaves that get a lot of suns. This makes them smaller or bigger because one side might get more sun which makes north leaves bigger.
Hypothesis: The leaves on the Northside are bigger.
Procedure:
1. Collect 35 leaves from the Northside and 25 leaves from the Southside.
2. A tree that is not in shade.
3. Press the leaves flat.
4. Trace the leaves onto graph paper using both sides of the page keeping North and South separate.
5.Count whole (w) and partial squares (p) and calculate the area of each leaf in squares 6. with the equation A= W+ ½ P.
Figure 2 is an example of the equation A= W+ ½ P. There are 4 whole´s and 8 parts so the area is 8 inches squared because 4+ ½ 8= 8.
7. Create a north and South leaf data table.
8. Discard leaves afterward.
9. Put the leaf area in order from smallest to greatest in each table.
10. Find the mean, median, mode of the 2 data sets as well as the entire range of 50 leaf data sets.
11.Create a histogram
Use the range to find the size of 7 bins. USe the nearest whole number
Sort leaves
Count leaves and creates a chart
12.Create histograms of individual data using Microsoft Excel or google docs
5. Results: The north's side leaves are bigger than the south side by a few a lot,
6. Conclusion: It was a warm sunny day and windy. The experimenter gathered 25 leaves from the North and South sides with all different sizes and colors. The hypothesis was supported based on the data collected. One reason why it was supported was that the North overall average was greater than the South. The Northside leaves are greater is that it is proven by facts. If someone compared a random south leave to a random north leaf, most times the North would be bigger because the probability of getting a big leaf is higher for North rather than South. The second piece of evidence from my data is that the South bin had more leaves in smaller bins while the North bin had an equal amount of leaves in the high and low bins. The third piece of evidence is that the Northside leaves had a bigger average than the South leaves. Also, the Southside had the smallest leaf while the Northside had the biggest leaf. The entire group also supported this.
7. Errors and ways to improve: Try to get different trees and instead of picking a few leaves in a certain area in the north and south, pick random ones. Also, gather more and different leaves. Different weather conditions could affect the leaves.
Figure 3, is the north bin where most of the leaves are bigger.
Figure 4, the south bin where most of the leaves are smaller.
Figure 5, the class north bin where some most leaves are small but some are big.
Figure 6, the class south bin where mostly all of the leaves are small.
Figure 7 is the tree used to pick leaves off.

Calculating acceleration involves dividing velocity by time — or in terms of SI units, dividing the meter per second [m/s] by the second [s]. Dividing distance by time twice is the same as dividing distance by the square of time. Thus the SI unit of acceleration is the meter per second squared .

HELP ME
Answers
Answer:
d = 4.47 [m]
Explanation:
To solve this problem we must make a free body diagram, where we can see the direction of the force acting with the appropriate angles. In the attached image we can see the free body diagram mentioned.
So in the image, we can see an angle of 65° with respect to the horizontal, therefore we can calculate the horizontal component of the force.
Fx = 22.4*cos (65)
Fx = - 9.46 [N] (it's negative because the force is pointing in the negative direction).
We can obtain the same result using 115° as the angle.
Fx = 22.4*cos (115)
Fx = 9.46 [N]
Now we know that work is defined as the product of the force by the distance, therefore we have.
Note: Always the work must be calculated with the force parallel
to the movement
W = F*d
Where:
W = work = 42.3 [J] (units of joules)
F = force parallel to the movement = 9.46 [N]
d = distance [m]
d = W/F
d = 42.3/9.46
d = 4.47 [m]
