This answer presumes that the value of all of the resistors in the circuit is known. The combined resistance in a parallel circuit is less than the value of any of the individual resistors. Depending on the number of resistors in a circuit, and their individual resistances, there are a few different methods to use … Read more

Write down what you think might happen (your hypothesis). Get an empty soda bottle. Partially fill it with water. Accurately mark the water level on the side of the bottle with tape, permanent marker, etc. Put in freezer overnight. Observe and make note of any changes to the level of the bottles contents.

Your Homework: Swimming - water friction, Hockey - ice friction, Sky Diving - air friction, Mud Wrestling - mud friction.

Friction is helpful in many everyday instances. It stops cars, motorcycles, bicycles, trains, buses and other vehicles through the friction created by the brakes. Basketball players use it to make quick turns on the court (squeaking shoes=friction). The space shuttle uses friction to slow down from an orbital speed of 17,400 miles per hour to … Read more

The formula to find the area of a square is: Side x side. Let's call a side X. Per the formula, we know that: X times X = 64, or X(squared) = 64. To answer this we need the square root of X(squared) [what times itself = X squared, which is X] as well as … Read more

1. The formula for the volume of a sphere is: 4/3*π*r³

Your sphere has a diameter of 3 Cm. The radius is one half of the diameter, or 1.5 Cm. This gives us: 4/3 x π x (1.5 x 1.5 x 1.5) 1. =1.3333 x π x (1.5 x 1.5 x 1.5) 2. =1.3333 x π x … Read more

Starting at the mark next to the number 1 (1 inch), go halfway to the end of the ruler and you will find a mark that should be one half of the length of the mark designating 1 inch. This will be the 1/2 inch mark. Again, go halfway to the end of the ruler … Read more

The oil pressure depends on the speed of the oil pump, which is driven internally by your engine. When your engine is at a lower r.p.m., as when you are at a stop, the oil pump is working at a lower speed/volume, resulting in lower pressure. This low pressure is not a normal operating condition … Read more

Tire sizing uses a cryptic formula that is really pretty easy to understand after you throw a little math at it. The tire size in … Read more

Your question, as asked, can not be fully answered. The perimeter of an object is the sum of the measure of its sides. If we are to presume that the rug is a square or a rectangle, it can have numerous dimensions. It could be 8 ft. X 8 ft. (8+8+8+8=32); or 1 ft. X … Read more

Gregor Mendel was the father of modern genetics. Through close and carefull examination of pea plants, he launched the field of botany as we know it today as well as influenced almost every branch of medical science.

A pineapple will float if it is placed into a liquid that, when displaced by the volume of the pineapple, the displaced liquid weighs more than the pineapple displacing it, causing buoyancy.

The answer to your question requires a couple of values: The length of a side of the square (base), and the height of the triangles.
You can then plug those numbers into these formulas:

1.Area Of A Square: A = bxb (where b = 1 side of the square)

2.Area Of … Read more

The correct name for a 34 sided polygon is triacontakaitetragon. See here for a breakdown of this rather confusing nomenclature

If space allows the addition of plants to your landscape, this can be an effective method.
