What does a mu mean in physics

Physics
1 answer:
ivolga24 [154]4 years ago
3 0

'mu' is a letter in the Greek alphabet.  It looks like this:  μ
If you need labels for quantities or variables in math or science,
you can use any letter from any alphabet you like ... just be sure
to explain what the symbol stands for somewhere on the page
where the equation or formula is.

I've seen 'mu' used to stand for 'micro-' when writing units.
For example:

" μ-meter " ... one millionth of a meter

" μ-farad " ... one millionth of a farad

" μ-second " ... one millionth of a second

RoseWind [281]
1. Bowling ball sitting in the rack:
kinetic energy = 0, because the ball is not in motion - we have only potential energy in this case
2. Bowling ball knocking pins down:
at the moment of knocking kinetic energy is increased, while the potential energy is decreased

A plane is flying due west at 34 m/s. It encounters a wind blowing at 19 m/s south. Find the resultant veloci
Drupady [299]

Answer:

<em>The resultant velocity has a magnitude of 38.95 m/s</em>

Explanation:

<u>Vector Addition</u>

Given two vectors defined as:

\vec v_1=(x_1,y_1)

\vec v_2=(x_2,y_2)

The sum of the vectors is:

\vec v=(x_1+x_2,y_1+y_2)

The magnitude of a vector can be calculated by

d=\sqrt{x^2+y^2}

Where x and y are the rectangular components of the vector.

We have a plane flying due west at 34 m/s. Its velocity vector is:

\vec v_1=(-34,0)

The wind blows at 19 m/s south, thus:

\vec v_2=(0,-19)

The sum of both velocities gives the resultant velocity:

\vec v =(-34,-19)

The magnitude of this velocity is:

d=\sqrt{(-34)^2+(-19)^2}

d=\sqrt{1156+361}=\sqrt{1517}

d = 38.95 m/s

The resultant velocity has a magnitude of 38.95 m/s
