If someone said that instruments that produce sounds by vibrating themselves are called aerophones. <u>False</u>

<h3>What is aerophones?</h3>

An aerophone is a musical instrument that makes sound primarily by forcing a body of air to vibrate without the use of strings or membranes, and without the vibration of the instrument itself significantly enhancing the sound.

<h3>What is aerophone instrument?</h3>

Any of a group of musical instruments known as aerophones, in which the initial sound is produced by a mass of vibrating air. Instruments that don't fit into any of these categories, such the bull-roarer and the siren, are also included in the basic types, along with woodwind, brass, and free-reed instruments.

<h3>What are African aerophones?</h3>

Aerophones, which create music by vibrating columns of air, are among the instruments used in Africa. Flutes, reed pipes, and trumpets and horns are the three major types of African aerophones.

How many components do vectors have, and what are they?
zepelin [54]

Answer:

There are two components for a two-dimensional coordinate system/vector.

Explanation:

For two-dimensional vectors, such as velocity, acceleraton, etc, there are two components, the x- and y-components.

These components could be rotated or translated, depending on the coordinate system.

Instead of rectangular cartesian system, the components could also be in the form of polar coordinates, such as radius and theta (angle).

For three-dimensional vectors, such as velocity in space, there are three components, in various coordinate systems.

Two identical small charged spheres are a certain distance apart, and each one initially experiences an electrostatic force of m
monitta

Answer:

1/4F

Explanation:

We already know thatThe electrostatic force is directly proportional to the product of the charge, from Coulomb's law.

So F α Qq

But if it is now half the initial charges, then

F α (1/2)Q *(1/2)q

F α (1/4)Qq

Thus the resultant charges are each halved is (1/4) and the first initial force experienced at full charge.

Thus the answer will be 1/4F

A plank rests on top of the axles of two identical wheels. Each wheel's outer radius is 0.25 meters and each wheel's axle has ra
kaheart [24]

Answer:

<u><em>The plank moves 0.2m from it's original position</em></u>

Explanation:

we can do this question from the constraints that ,

  • the wheel and the axle have the same angular speed or velocity
  • the speed of the plank is equal to the speed of the axle at the topmost point .

thus ,

<em>since the wheel is pure rolling or not slipping,</em>

<em>⇒v=wr</em>

where

<em>v - speed of the wheel</em>

<em>w - angular speed of the wheel</em>

<em>r - radius of the wheel</em>

<em>since the wheel traverses 1 m let's say in time 't' ,</em>

<em>v_{w}=\frac{distance}{time} =\frac{1}{t}</em>

∴

⇒w=\frac{v_{w}}{r} = \frac{1}{t*0.25}

the speed at the topmost point of the axle is :

⇒v_{a}=w*r\\v_{a}=\frac{1}{t*0.25} *0.05\\v_{a}=\frac{1}{5t}

this is the speed of the plank too.

thus the distance covered by plank in time 't' is ,

⇒d=v_{a}*t\\d=\frac{1}{5t} *t\\d=\frac{1}{5} = 0.2m
