Why is there no right angles in nature?
Everything organic is designed to take the path of least resistance towards its source of nourishment which in almost all cases, either directly or indirectly is the Sun! Since the Sun is up there and the only opposing force is gravity which pulls a body downwards the only two forces acting upon any body is linear. Therefore there is no reason for a plant or being to grow sidewards unless its path towards the source of nourishment is obstructed by anything. Since right angles present absolute resistance, it cannot survive for long as nature is in a continuous state of change and that which offers absolute resistance cannot survive for long. For example if a flowing river is presented with a right angled obstruction, it will erode the points of absolute resistance till the obstruction erodes to a state where it offers the least resistance to the flow of the river.

What is an Incomplete Grade?
When a college student is unable to complete the coursework for a particular class, the instructor may give the student an incomplete grade. An incomplete grade is granted for a temporary period of time, and it gives the student an opportunity to complete the required coursework by a certain date. Read on to learn the ins and outs of getting an incomplete grade.Are college instructors required to give students an incomplete grade?No, college instructors are usually not required to give a student an incomplete grade. However, if a student has successfully completed a majority of the coursework for that class, the instructor may give the student an incomplete grade (if the student has a valid reason). There are several reasons why a student cannot the coursework for that semester or term:IllnessCar accidentA death in the immediate familySevere personal problems (e.g. divorce or financial problems)Working extra hoursHow is an incomplete grade reflected on my college transcript?If you receive an incomplete in a class, your grade for that class is I. The letter I will appear on your college transcript next to that specific class. However, once you submit the required coursework for that class, your grade will be changed to reflect the new grade. Please note that although the incomplete grade will appear on your transcript, it does not affect your grade point average.How long do I have to complete the remaining coursework?Generally speaking, you have anywhere from one semester/quarter to a year to submit your coursework for an incomplete grade. Your instructor will tell you the deadline for submitting your coursework for that class.What happens if I do not complete the required coursework by the deadline?If you fail to complete all of your coursework in a timely manner, the incomplete may automatically change to a letter grade "F" on your transcript. As a result, the F will lower your grade point average. In addition, if you receive an F in a class, you will need to take that class again (if the class is a graduation requirement for your degree program).As you can see, instructors do grant incomplete grades when it is necessary. If you ever receive an incomplete grade in a class, it is important to complete the remaining coursework by the specified due date. Keep in mind that it is your responsibility to complete your coursework for that class. Do not depend on your instructor to contact you about the incomplete grade. Be sure to follow up with your instructor and with the Registrars office at your school, once your complete your coursework for that class.

8 ft or 96 in X 4 ft or 48 in = 4,608 square(inche)s
Is long an adverb?
It can be. Normally long is an adjective (a long walk, a long time) but it can act as its own adverb form in uses such as "Have you waited long?" (i.e. for a long time) or idiomatic uses such as "all night long."

How do you assemble a lever?
The lever itself is any rigid item, it should be long, rigid and strong. To work it needs a Fulcrum. A rock or similar thing will do. You take your Lever, place it under the object to be moved, place the lever over the Fulcrum, then push the lever to move your object.
Would it be easier to use a lever and fulcrum?
Depends on the job at hand. The most common use is to multiply force so you can move something that weighs more than you can lift on your own. In doing this you give up distance. Place the lever and fulcrum so that the fulcrum is close to the 'load'. When you push on the long end of the lever it moves a long distance with a small effort, The load will be lifted a shorter distance.
When children play on a see-saw what simple machine describes the action of the long board that they sit on?
It functions as a lever, with a fulcrum in the center.
What can be increased on a lever?
the length of the fulcrum can be increased in proportion to the length behind the pivot point or leverage point. this will increase the power delivered by the lever. Also the force applied to the end of the fulcrum will also delivers more power from the lever. it is said amongst physic students and thier teachers that if you have a long enough lever and can place against the proper stationary pivot point (heal) you can move anything.
Is a lever a lever?
A lever is a simple machine, which can be part of more complex mechanical devices. The basic lever consists of a stiff bar or rod placed across a support structure called a fulcrum. Using the lever, an applied force can be multiplied. This can convert small forces over a long distance into a large force over a short distance (or vice versa).The lever takes advantage of the formula F = MD (force= mass x distance).Levers are of three basic types, depending on the location of the force and the fulcrum.The fulcrum is between the applied force and the load (output force). Example : seesaw, crowbarThe load is between the force and the fulcrum. Example : wheelbarrow (weight carried by wheel)The force is applied between the fulcrum and the load. Example : human elbow, when bendingA lever is a simple machine consisting of a beam or rigid rod pivoted at a fixed hinge, or fulcrum.Any object which when used has a pivot point (a point it turns about) sometimes called the fulcrum, so that you can apply a force at one point (called effort) and a force is then applied on another object (called resistance). Because of differing distances between the fulcrum and the effort compared to the distance between the fulcrum and the resistance, the effort may be increased, which is the usual effect desired, or speed may be increased.The claw of a hammer is an example. The pivot point it the point of contact with the wood. A nail driven into the wood cannot be pulled by your hand alone, but your hand supplied the effort on the handle of the hammer and the claw pulls on the nail, the resistance, and the effort becomes greater so that it pulls the nail.
When play on a see-saw the long board that they sit on acts like an?
It acts like a lever - with the central fixing post simulating the fulcrum.
What type of simple machine is a spatula?
There are six different simple machines: the lever, the pulley, the wheel and axle, the screw, the wedge, and the inclined plane. A shovel would be a wedge, since it separates portions of an object. A seesaw would be a lever, since it applies force at one end and delivers at the other. A baseball bat is also a lever, since when you swing it, you apply force from one end onto the incoming baseball on the other. The pulling end of a hammer would be a lever, since it applies force on one end, which pulls out the nail on the other.

How can a lever generate a large force?
A lever works against a fulcrum. If there is a shorter section of the lever at one end of the fulcrum and a longer section at the other end, then you can exert a force on the longer end of the lever, and have a greater force exerted on the shorter end. That is because you are moving the long end through a longer distance than the shorter end moves, and all the force exerted over the longer distance is then effectively compressed into the shorter distance.
How long would a lever need to be to lift earth if the force was 1 newton and the pivot was right in front of the earth. pysics?
This question is hard to answer. How much force are you applying to the lever? In other words, how strong are you? Also where are you placing the fulcrum? In a seesaw the fulcrum, that's the part that's touching the ground is in the middle. I hope you can see why this is hard to answer.
