A closed container initially holds 50 monatomic Aparticles that have a combined energy of 480 units. After 100 monatomic B parti

cles with a combined energy of 720 units are added to the container, the system is allowed to come to thermal equilibrium.Part A) At equilibrium, how many energy units does each A particle have?Part B) At equilibrium, how many energy units does each B particle have?

Answer:

"8 units" is the appropriate answer.

Explanation:

According to the question,

Throughout equilibrium all particles are of equivalent intensity, and as such the integrated platform's total energy has been uniformly divided across all individuals.

Now,

The total energy will be:

= 480+720

= 1200 \ units

The total number of particles will be:

= 50+100

= 150

hence,

Energy of each A particle or each B particle will be:

= \frac{1200}{150}

= 8 \ units

Which of the following is true of an adiabatic process?
poizon [28]

Adiabatic process is that process in which heat of a closed system will remain conserved or we can say that system can not exchange its thermal energy from its surrounding

So here from 1st law of thermodynamics we can say

\Delta Q = \Delta U + W

since we know that

\Delta Q = 0

so we will have

0 = \Delta U + W

so we have

-\Delta U = W

so here correct answers are

<em>A. -ΔU = W  </em>

<em>B. Heat is constant. </em>

The radar gun measures the frequency of the radar pulse echoing off your car. By what percentage is the measured frequency diffe
mel-nik [20]

Question: A. The state highway patrol radar guns use a frequency of 9.15 GHz. If you're approaching a speed trap driving 30.1 m/s, what frequency shift will your FuzzFoiler 2000 radar detector see?

B. The radar gun measures the frequency of the radar pulse echoing off your car. By what percentage is the measured frequency different from the original frequency? (Enter a positive number for a frequency increase, negative for a decrease. Just enter a number, without a percent sign.)?

Answer:

The frequency change percentage is 9.94%

Explanation:

The frequency shift can be calculated as follows.

F= \frac{V+V_{0}}{V+V_{s}}

   = 9.05GHz\times\frac{343m/s+0}{343m/s+(-31.3m/s)}

   =9.95 GHz

So the frequency change seen by the detector is 9.95 - 9.05

% difference= \frac{0.9}{9.05} \times100

                    = 9.94%

A motorist traveling at 12 m/s encounters a deer in the road 39 m ahead. If the maximum acceleration the vehicle’s brakes are ca
Vera_Pavlovna [14]

Answer:

Explanation:

Given

Motorcyclist speed=12 m/s  

maximum acceleration=-6 m/s^2

distance=39 m

Let x be the distance traveled by motorist in his reaction time

therefore remaining 39-x will be traveled with -6m/s^2 acceleration

v^2-u^2=2as

s=39-x

v=0

u=12 m/s

0-12^2=2\left ( -6\right )\left ( 39-x\right )

x=27 m

Therefore he traveled 27 m in his reaction time

27=12\times t

t=2.25 s

(b)If his reaction time is 2.56 sec

then distance traveled in his reaction time

x_0=12\times 2.56=30.72 m

Remaining distance 39-30.72=8.28 m

therefore its velocity when it reaches the deer

v^2-u^2=2as

v^2=12^2+2\times \left ( -6\right )\times 8.28=44.64

v=6.681 m/s
