Physical properties are properties that can be measured or observed without changing the chemical nature of the substance. Some examples of physical properties are: color (intensive) density (intensive) volume (extensive)

Measurement information used to describe something is called data.

A measurement consists of two parts – the amount present or numeric measure, and the unit that the measurement represents within a standardized system.

A well defined and agreed upon referent used as a standard in all systems of measurement is called. Metric system.

Acceleration is the rate of change in the velocity of an object. Velocity can change in three different ways. Speed up, slow down, or changing direction. All three of these changes are technically called acceleration.

A PROCESS OF COMPARING A PROPERTY TO A WELL DEFINED AND AGREED UPON REFERENT IS CALLED. MEASURMENT.

The symbol “Δ” is used to refer to an object’s density.

What did some of the ancient natural philosophers achieve? They suggested the idea of matter being composed of atoms. They developed the concept of basic components (i.e., elements making up matter).

As the cube size increases or the cell gets bigger , then the surface area to volume ratio – SA:V ratio decreases. When an object/cell is very small, it has a large surface area to volume ratio, while a large object/ cell has a small surface area to volume ratio.

The region or space of the plane figure or object is called area. The quantity of space contained by an object is called volume. Plane figures have area while solid shapes have volume. Area describes the amount of space enclosed, whereas volume determines the capacity of solids.

The increase in volume is always greater than the increase in surface area. This is true for cubes, spheres, or any other object whose size is increased without changing its shape.

Surface Area Formulas:

1. Volume = (1/3)πr2h.
2. Lateral Surface Area = πrs = πr√(r2 + h2)
3. Base Surface Area = πr2
4. Total Surface Area. = L + B = πrs + πr2 = πr(s + r) = πr(r + √(r2 + h2))

The formula for the volume of a cylinder is V=Bh or V=πr2h . The radius of the cylinder is 8 cm and the height is 15 cm.

In 1995, mathematician Michael Reid found a Rubik’s Cube configuration called a “superflip” and proved that it required at least 20 moves to solve. That sets a lower limit on what God’s Number could be. The remaining question, then, is whether or not there are any cubes that need more than 20 steps to solve.

What is a cubed number?

1. When you multiply a whole number (not a fraction) by itself, and then by itself again the result is a cube number.
2. The easiest way to do this calculation is to do the first multiplication (3×3) and then to multiply your answer by the same number you started with; 3 x 3 x 3 = 9 x 3 = 27.

A cube number is a number multiplied by itself 3 times. This can also be called ‘a number cubed’. The symbol for cubed is ³. 2³ = 2 × 2 × 2 = 8.

The cube of the number 6, or 6 cubed, is 216. To find the cube of a number, x, we raise the number x to the third power, or to the exponent 3.

A perfect cube is a number which is equal to the number, multiplied by itself, three times. For example, 8 is a perfect cube because 3√8 = 2.

Since 25 is a natural number and the square root of 25 is a natural number (5), 25 is a perfect square.

1, 8, 27, 64, 125, 216, 343, 512, 2, 9, 16, 28, 35, 54, 65, 72, 91, 3, 10, 17, 24, 29, 36, 43, 55, 62.

Informally: When you multiply an integer (a “whole” number, positive, negative or zero) times itself, the resulting product is called a square number, or a perfect square or simply “a square.” So, 0, 1, 4, 9, 16, 25, 36, 49, 64, 81, 100, 121, 144, and so on, are all square numbers.

Jewish tradition holds that the number 36 has had special significance since the beginning of time: According to the Midrash, the light created by God on the first day of creation shone for exactly 36 hours; it was replaced by the light of the Sun that was created on the Fourth Day.

35 is not a perfect square.

6

Explanation: The positive and negative square roots of 36 are 6 and −6 .

The square root of 36 is 6. It is the positive solution of the equation x2 = 36. The number 36 is a perfect square….Square Root of 36 in radical form: √36.

There is no equivalent quantity to a root of any negative number. It can’t be placed anywhere in the number line. Hence, √-36 is equal to 6i. It can’t be expressed into a real number in any way.
