Based on your author, you will need to write a bio, share what they are famous for, how they were influenced by their surroundings, and peers. This is not just a report make it your own. You will need to use proper grammar, spelling, and sentence structure. Make sure to cite your sources.  You will find a link how to cite in APA format.

determine the value of the coefficient of the given gravitational field constant 5.1 N/kg.

01*. A displacement D of 100m from the origin at an angle of 370
 above the x-axis is
the result of three successive displacements: d1 of 100m along the negative x-axis,
d2 of 200m at an angle of 1500
 above the x-axis, and a displacement d3. Find d3.

A high-performance gasoline engine has a compression ratio of 10:1, meaning that air entering the cylinders is compressed to one-tenth its volume as the piston rises. If air enters this engine's cylinders at 290 K and 1 atm, find (a) the pressure and (b) the temperature of the air at full compression. Assume adiabatic compression.

A diesel engine works at a high compression ratio to compress air until it reaches a temperature high enough to ignite the diesel fuel. Suppose the compression ratio (ratio of volumes) of a specific diesel engine is 25 to 1. If air enters a cylinder at 1 atm and is compressed adiabatically, the compressed air reaches a pressure of 66.0 atm. Assuming that the air enters the engine at room temperature (24.5°C) and that the air can be treated as an ideal gas, find the temperature (in K) of the compressed air.

One cylinder in the diesel engine of a truck has an initial volume of 600cm^3. air is admitted into the cylinder at 30 degrees C and a pressure of 1.0 atm. the piston rod then does 400J of work to rapidly compress the air. what are its final temperature and volume?

A boy pushes a box with a force of 75N. How far will the box travel if he does 400J of work

A box contains 5 white and 4 black balls. Two balls are picked together at random from the box.

What is the probability that these two balls are of different colours ?

1.          1/2
2.          5/18
3.          5/9

Write a letter as if you are a foreign exchange student living in America. Pretend you are writing to your family in your homeland and you must explain an American custom they know nothing at all about.

To write a convincing letter, you must examine the American custom through the eyes of an outsider. What may seem perfectly natural and logical to us may seem silly to someone from a foreign country.

Think about what foreign students must think when they are first confronted with American children dressing in rags and outlandish costumes, going out knocking on doors begging for candy, and threatening to pull a trick on the people who have no candy for them. Or what about American customs at Christmas and Thanksgiving?

Your letter must be a minimum of three paragraphs containing 5-7 sentences each.
