# How do you use scientific notation in mastering physics?

Mastering does not support E notation. To include a large or small number in your answer to a Mastering question, use the provided Equation Editor menus or keyboard shortcuts to enter the number in scientific notation. The keyboard shortcut for multiplication is the asterisk * (shift-8 on most keyboard layouts).

## How do you write units in mastering physics?

For example, if SI units are required, m (for meters) would be correct but yd (for yards) would not. Mastering can accept as correct any unit answer that is equivalent to the correct answer. For example, if the correct answer is 2 V and you enter 2000 mV, you will receive full credit.

## How do I enter MS in mastering physics?

How do I enter units? Type one space between the number and the units, and then enter the units in the correct format. For example, a velocity would be entered as “1.2 m/s”, not “1.2m/s”.

## What are accepted units?

Accepted Unit means each Unit that has been purchased by the Owner Trustee pursuant to the Participation Agreement.

## What is the magic number in mastering physics?

Although you could try to guess the magic number you would most likely exhaust your tries before getting the correct answer. To help you, the magic number is , where is a number between 1 and 10.

## What is the unit for frequency?

The number of periods or cycles per second is called frequency. The SI unit for frequency is the hertz (Hz). One hertz is the same as one cycle per second.

## What units are acceleration?

Units. Acceleration has the dimensions of velocity (L/T) divided by time, i.e. L T−2. The SI unit of acceleration is the metre per second squared (m s−2); or “metre per second per second”, as the velocity in metres per second changes by the acceleration value, every second.

## What value should you use as the area of the base when calculating the answer to Part C?

What value should you use as the area of the base when calculating the answer to Part C? 11.76 cm^2 is the correct, unrounded value of the area of the base.

## What are the 7 basic units of measurement?

• Length – meter (m)
• Time – second (s)
• Amount of substance – mole (mole)
• Electric current – ampere (A)
• Temperature – kelvin (K)
• Luminous intensity – candela (cd)
• Mass – kilogram (kg)

## What are the three types of SI unit?

F.P.S. system (or British system): In this system, the unit of length is foot (ft), unit of mass is pound (lb) and unit of time is second (s). M.K.S. system (or metric system): In this system, the unit of length is metre (m), unit of mass is kilogramme (kg) and unit of time is second (s).

## How do you write scientific notation in mastering chemistry?

Use scientific notation, not e (which Mastering evaluates as the constant 2.718…) or E. For example, enter 1.23*10^5 instead of 1.23e+5 or 1.23E+5. Use commas only as separators between multiple expressions within a single answer box, such as “1999,2009”. Do NOT use commas in any large number, such as 32000.

## How do you write in Pearson?

1. Enter |y.
2. Choose and type y.

## Do you lose points for using hints on mastering chemistry?

There is no penalty for leaving hint questions unanswered. You lose all possible credit for the hint question if you choose Request Answer. If you don’t know the answer, it may be best to leave the hint question blank (see above).

## What is magic numbers in chemistry?

The concept of magic numbers in the field of chemistry refers to a specific property (such as stability) for only certain representatives among a distribution of structures. It was first recognized by inspecting the intensity of mass-spectrometric signals of rare gas cluster ions.

## What is the number of magic?

It is 1729. Discovered by mathemagician Srinivas Ramanujan, 1729 is said to be the magic number because it is the sole number which can be expressed as the sum of the cubes of two different sets of numbers.

## What is 1hz?

It is measured in hertz (Hz), an international unit of measure where 1 hertz is equal to 1 cycle per second. Hertz (Hz) = One hertz is equal to one cycle per second. Cycle = One complete wave of alternating current or voltage.

## How do you write Hz?

As with every SI unit named for a person, its symbol starts with an upper case letter (Hz), but when written in full it follows the rules for capitalisation of a common noun; i.e., “hertz” becomes capitalised at the beginning of a sentence and in titles, but is otherwise in lower case.

## What is the unit of heat in SI unit?

Generally, in the SI system, all forms of energy are measured in terms of joules. Notably, heat is a form of energy, and therefore the SI unit of heat is also joules (J) which are defined as the amount of energy needed to raise the temperature of a given mass by one degree.

## What is the unit for velocity?

Velocity is a vector expression of the displacement that an object or particle undergoes with respect to time . The standard unit of velocity magnitude (also known as speed ) is the meter per second (m/s).

## How do you write m s2?

The meter per second squared (symbolized m/s 2 or m/sec 2 ) is the Standard International ( SI ) unit of acceleration vector magnitude. This quantity can be defined in either of two senses: average or instantaneous.

## What unit is newton?

newton, absolute unit of force in the International System of Units (SI units), abbreviated N. It is defined as that force necessary to provide a mass of one kilogram with an acceleration of one metre per second per second.

## How do you find the volume of a triangle formula?

volume = 0.5 * b * h * length , where b is the length of the base of the triangle, h is the height of the triangle and length is prism length.

## How do you calculate area?

To find the area of a rectangle or a square you need to multiply the length and the width of a rectangle or a square. Area, A, is x times y.

## Where is the base of a triangle calculator?

1. Note the area of the triangle and multiply it by 2;
2. Note the height of the triangle;
3. Divide the result from step 1 by the height;
4. The result is the base of the triangle.
