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”.
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.
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.
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 meters per second squared?
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.
How do you read meters per second?
Why is it meters per second squared?
Because acceleration is velocity in m/s divided by time in s, the SI units for acceleration are m/s2, meters per second squared or meters per second per second, which literally means by how many meters per second the velocity changes every second. Was this answer helpful?
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 7 fundamental quantities and their units?
The present SI has seven base quantities: time, length, mass, electric current, thermodynamic temperature, amount of substance, and luminous intensity.

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.
How do you write scientific notation in Pearson?
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 type in on Pearson math?

Is m s2 same as as m·s 2?
The metre per second squared is the unit of acceleration in the International System of Units (SI). As a derived unit, it is composed from the SI base units of length, the metre, and time, the second. Its symbol is written in several forms as m/s2, m·s−2 or m s−2, , or less commonly, as m/s/s.
Why is it 9.8 meters per second squared?
One newton equals one kilogram metre per second squared. Therefore, the unit metre per second squared is equivalent to newton per kilogram, N·kg−1, or N/kg. Thus, the Earth’s gravitational field (near ground level) can be quoted as 9.8 metres per second squared, or the equivalent 9.8 N/kg.
How fast is 1 meter per second squared?
metres per second squared to miles per hour per second conversion. Conversion number between metres per second squared [m/s²] and miles per hour per second [mph/s] is 2.2369362920544. This means, that metres per second squared is bigger unit than miles per hour per second.
What does m·s minus 1 mean?
It means meters per second (recall that s−1=1/s, so ms−1=m/s).
Is m/s speed or velocity?
The metre per second is an SI derived unit of both speed (scalar quantity) and velocity (vector quantity (which have direction and magnitude)), equal to the speed of a body covering a distance of one metre in a time of one second.
