The definition of speed is (distance covered) / (time to cover the distance) .
So a unit of speed has to be (a unit of length) / (a unit of time) .
Here are several perfectly fine units of speed:
-- miles per hour
-- feet per second
-- meters per second
-- kilometers per hour
-- inches per second
-- centimeters per minute
-- yards per Century
-- furlongs per fortnight
-- nanometers per microsecond
-- Smoots per week
-- parsecs per millenium
Answer:
15,00kg
Explanation:
here's your solution
=> force = 45,000N
=> acceleration = 30m/s^2
=> mass = ?
=> Mass = force/acceleration
=> mass = 45,000/30
=> mass = 15,00kg
hope it helps
Answer:
The answer is C
Explanation:
The radius is HALF of the diameter...so you would have to find a dividing "2". :)
Like so many others in math and science,
this question raises many other questions.
A few of them are:
-- What does "the following" mean ?
-- What does "accerlation" mean ?
and
-- What are the answer choices ?
==> (any unit of length) divided by (any unit of time x any unit of time)
is a unit of acceleration.
==> (any unit of speed) divided by (any unit of time)
is also a unit of acceleration.
