Malleability

<h3><u>Knowledge</u><u> </u><u>Enhancer</u><u> </u></h3>

★ <u>Malleability</u>: The property which allows the metal to be hammered into thin sheets is called malleability.

★ <u>Brittleness</u><u>:</u> The property due to which non-metals break down on hammering is called brittleness .

★ <u>Ductility</u><u>:</u> The property which allows the metal to be drawn into wires is called dutility.

Two speakers are spaced 15 m apart and are both producing an identical sound wave. You are standing at a spot as pictured. What
IgorLugansk [536]

Answer:

Frequency is 213.04\ s^{-1}.

Explanation:

Distance between source 1 from the receiver , S_1 =\sqrt{10^2+22^2}=24.17\ m.

Distance between source 2 from the receiver , S_2=\sqrt{5^2+22^2}=22.56\ m.

Now ,

Path difference , r = S_1-S_2=24.17-22.56=1.61\ m.

We know, for constructive interference path difference should be integral multiple of wavelength .  

Therefore, r=n\times \lambda

It is given that n = 1,

Therefore, \lambda=1.61\ m.

Frequency can be found by , \nu=\dfrac{v}{\lambda}= \dfrac{343}{1.61}=   213.04\ s^{-1} .

Hence, this is the required solution.

Average velocity is different than average speed because calculating average velocity involves ?
Studentka2010 [4]
Direction!

Velocity is a vector quantity and speed is a scalar quantity. Vector quantities includes both magnitude and direction, while scalar quantities only have magnitude. :)

A vector has an x-component of length 10 and a y-component of length 3. What is the angle of the vector? (Hint: Use the inverse
Sonja [21]
The vector, the x-component and the y-component form a rectangle triangle where the vector is the hypothenuse and the x and y components are the two sides.
Calling \alpha the angle between the vector and the horizontal direction (x), the two sides are related to \alpha by
\tan \alpha  =  \frac{v_y}{v_x}
where vy and vx are the two components on the y- and x-axis. Using vx=10 and vy=3 we find
\tan \alpha  =  \frac{3}{10} =0.3
And so the angle is
\alpha = \arctan (0.3)=16.7^{\circ}

Does sand stay sand forever?
Gemiola [76]

Answer:

No sand doesn't stay sand forever.

Explanation:

  • We may have a thought that the sand we see on the beach areas are always the same one for eternal, but it is not true.
  • Due to different activities like beach nourishment, sand replenishment etc. the sand in the beach areas are changed and replaced.
  • If the sand remained there for long time, it also affects the sand eating organisms and plants.
