The conventional system of signs that indicate relative durations of long and short sounds is called.
Rudiy27

Musical notation is the term used to describe the common system of signs used to denote the relative duration of long and short sounds.

<h3>What is a musical notation?</h3>

Music notation, often known as musical notation, is any technique used to graphically express audibly perceived music performed with instruments or sung by a human voice using written, printed, or other symbol-based representations. This includes notation for periods of silence like rests.

Throughout history, many civilizations have used different types of notation, and the knowledge of early musical notation is generally sparse. Different musical genres and cultural groups employ various methods of music notation, even during the same time period, such as the 2010s. For instance, while sheet music with staves and note-heads is the most popular method for professional classical musicians, the Nashville Number System is the main method used by professional country music session musicians.

A force of 5 N produces an acceleration of 2 m/s2 on the object. What is the mass of the object?
hichkok12 [17]

Hello!

A force of 5 N produces an acceleration of 2 m/s2 on the object. What is the mass of the object ?

Data:

F (force) = 5 N

m (mass) = ?

a (acceleration) = 2 m/s²

Solving:

F = m*a

5 = m*2

2\:m = 5

m = \dfrac{5}{2}

\boxed{\boxed{m = 2.5\:kg}}\end{array}}\qquad\quad\checkmark

Answer:  

2.5 kg

A machine in an ice factory is capable of exerting 3.31 × 102 N of force to pull large blocks of ice up a slope. The blocks each
tankabanditka [31]

Answer:\theta =1.43 ^{\circ}

Explanation:

Given

Force exerted by machine F=3.31 \times 10^2 N

Weight of Block W=mg=1.32\times 10^4 N

Considering inclination to be \theta

After resolving Forces We get

mg\sin \theta =F

\sin \theta =\frac{F}{mg}

\sin \theta =\frac{3.31 \times 10^2}{1.32\times 10^4}

\sin \theta =2.507\times 10^{-2}

\sin \theta =0.02507

\theta =\sin ^{-1}(0.02507)

\theta =1.43 ^{\circ}
