Mechanical waves are those waves that require a material medium for propagation.

<h3>What are mechanical waves?</h3>

Generally, we define a wave as a disturbance along a medium which transfers energy. It then follows that waves move energy from one point to another.

Waves can be classified as;

Mechanical waves
Electromagnetic waves

Mechanical waves are those waves that require a material medium for propagation such as sound, and waves on a strings.

Answer:

A mechanical wave is a wave that is not capable of transmitting its energy through a vacuum. Mechanical waves require a medium in order to transport their energy from one location to another.

A sound wave is an example of a mechanical wave.

If the distance between two masses is tripled, the gravitational force between changes by a factor of:_______

adell [148]

Answer:

option A

Explanation:

given,

distance between two masses is doubled

new distance, r' = 3 r

using gravitational force equation

$F = \dfrac{GMm}{r^2}$ ............(1)

new gravitational force

$F' = \dfrac{GMm}{r'^2}$

now from the given condition

$F' = \dfrac{GMm}{(3r)^2}$

$F' = \dfrac{GMm}{9r^2}$

$F' = \dfrac{1}{9}\dfrac{GMm}{r^2}$

now, from equation (1)

$F' = \dfrac{1}{9}F$

$\dfrac{F'}{F} = \dfrac{1}{9}$

now, the change in gravitational force factor is equal to $\dfrac{1}{9}$

Hence, the correct answer is option A

Forces of 2 newtons and 3 newtons are acting on an object as shown in the drawing below. Calculate the resultant force in newton

Kipish [7]

Answer:

Hey mate

Your answer will be 5 N Upwards. 

I will explain this to you.

In the attachment we can see that there are two forces acting on the object from the same side. And we know that when force acts from the same direction. Then the total force

=> sum of all the forces in that particular direction.

I hope you got it :)

Name the material used to transfer of charges from one body to other

Evgesh-ka [11]

Answer:

conductor

Explanation:

A "conductor" is a material that allows the charges to pass freely from one body to the other. This causes a movement among the electrons and this means that the charge will be passed entirely to the object receiving it. This is also called "conductive material."

Examples of conductors are: copper, aluminum, gold, silver, seawater, etc.

The opposite of conductors are called "insulators." These do not allow the free movement of charges from one object to the other.

Examples of insulators: plastic, rubber, paper, glass, wool, dry air, etc.

A system consists of a disk rotating on a frictionless axle and a piece of clay moving toward it, as shown in the figure above.

cestrela7 [59]

Explanation:

Forgive me If I am wrong, it's been a while since I've studied Torque.

The formula for the angular momentum is

momentum= I*w.

We can also write I*W as 1/2MR^2 * W so the extra mass coming from the block of clay would most likely cause the angular momentum to increase from the amount it was before.

Table C: Average Speeds for Lower Racetrack

Blababa [14]

Answer:

Centripetal Acceleration = v^2/r

= (circumference/time)^2/r

= (2*pi*r/t)²)/r

= ((2³.14*50/14.3)²)/50

= 9.64 m/s²
