Answer: Entropy

Explanation:

Entropy is the measure of degree of randomness or disorder.

The systems which have more randomness or disorder of particles have more value of entropy and the system with more ordered arrangement of particles will have less entropy.

Solids with more ordered arrangement of atoms have less entropy and gases with random movement of molecules have more entropy.

What does B represent?

jenyasd209 [6]

B is a trough.

A trough is the opposite of a crest, in that it occurs at the maximum negative displacement of a wave.

In this problem, A would be the crest, C would be the wavelength, and D would be the amplitude.

Hope this helps!! :)

A rocket is fired at 100 m/s at an angle of 37, what was its total speed when it landed?

disa [49]

Answer:

100 m/s

Explanation:

Let find the velocity components first

Fx = 100 * cos (37) = 79.86 m/s

Fy = 100 * sin (37) = 60.18 m/s

applying motion equations

Horizontal motion

assuming no acceleration in horizontal direction we can assure that the ending velocity component will still remain Fx = 79.86 m/s

Vertical motion (upwards)

V² = U² +2as

= 60.18² + 2*(-10)*0

Fy = 60.18 m/s

Total speed = √(F²x+F²y) = 100 m /s

*** You can take the same answer considering the Energy

An undamped oscillator has period ro= 1.000 s, but I now add a little damping so that its period changes to r i= 1.001 s.

Firlakuza [10]

This Question has mistakes.Correct question is

An undamped oscillator has period τo=1.000s , but I now add a little damping so that its period changes to τ1=1.001s.

What is the damping factor β? By what factor will the amplitude of oscillation decrease after 10 cycles? Which effect of damping would be more noticeable, the change of period or the decrease of the amplitude?

Answer:

β=0.28 /sec

Amplitude=0.0606

Explanation:

$T_{o}=2\pi /w\\T_{1}=2\pi /\sqrt{w^{2} -\beta^{2} }\\ As\\T_{o}=1 \\T_{1}=1.001\\From T_{o}\\w=2\pi \\So\\T_{1}=w/\sqrt{w^{2} -\beta^{2} }\\\beta =0.00447w\\\beta =0.00447(2\pi )\\\beta =0.28sec^{-1}\\ Amplitude=Ae^{-\beta t}\\ after\\ t=10T_{1}\\so\\Ae^{-\beta(10t_{1}) }=e^{-\beta(10t_{1}) }\\=e^{-\(0.28)(10)(1.001) }\\Amplitude=0.0606$
