Explanation:
the state or quality of being efficient or able to accomplish something
There could be more than just one answer, since kilograms can be converted to grams, to miligrams, etc.

or

Why?
Let's remember some conversion factors to work with kilograms (kg)

So, we are given the momentum:

We can rewrite the units of the momentum (equivalent) as follow:

and

Note: There could be more equivalent units for the momentum, in example, we could work with equivalent units for meters (distance) and seconds (time).
Have a nice day!
Answer:

Explanation:
Given data
Length L=0.24 m
Magnetic field B=7.0 T
Current I=90 A
To find
Number of turns N
Solution
As we know that magnetic field is given as:

Rearrange the equation and solve for N
So

The statement ‘A tertiary source is the most desirable source for a
researcher to use’ is false. It should be that your source is primary because
it is more reliable and is related to the research you have been working on.
For this case, what we can do is use the Pythagorean theorem to find the magnitude of the displacement of the car.
We have then

From here, we clear the value of d.
We have then:

Rewriting:
Answer:
The magnitude of the car's displacement is:
d = 20 miles
