Two objects form a closed system. One object, which is at 400 K, absorbs 25.0 kJ of heat from the other object,which is at 500 K. What is the net change in entropy ΔSsysΔSsysDeltaS_sys of the system? Assume that the temperatures of the objects do not change appreciably in the process

Answers

Explanation:

The given data is as follows.

        = 400 K,     = 500 K,  

= 25 kJ = 25000 J   (as 1 kJ = 1000 J)

Now, we will calculate the change in entropy as follows.

           

Putting the given values into the above formula as follows.

           

                      =      

                      = 250 J/K

Hence, we can conclude that change in entropy is 250 J/K.

Three Difference between wavelength and frequency ?

Answers

Hi,
Wavelength: 
1.Wavelength measures the distance from one point of a wave to the same point on an adjacent wave.
2.Wavelengths are measured in nanometres.
3.The wavelength of the wave is inversely proportional to the energy of the wave.
Frequency:
1.Frequency represents how many waves are produced from the source per second.
2.Frequencies are measured in hertz or waves per second.
3.The frequency is linearly proportional to the energy of the wave.
Hope this Helps you.

The electrons that produce the picture in a TV set are accelerated by a very large electric force as they pass through a small region in the neck of the picture tube. This region is 1.5 cm in length, and the electrons enter with a speed of 1 × 105 m/s and leave with a speed of 2.5 × 106 m/s. What is their acceleration over this 1.5 cm length?

Answers

The acceleration given the initial and final velocity and the distance can be calculated through the equation,
 
           a = ((Vf)² - (Vi)²) / 2d

where d is the distance, Vf is the final velocity, Vi is the initial velocity and a is the acceleration. 

Substituting the known values,
  
        a= ((2.5 x 10⁶ m/s)² - (1 x 10⁵ m/s)²) / 2 (15/100)
            a = 2.08 x 10¹³ m/s²

ANSWER:  a = 2.08 x 10¹³ m/s²

3. What is the bandwidth of a signal composed of frequencies from 60 Hz to 600 Hz?

Answers

The bandwidth of the given signal composed of frequencies from 60 Hz to 600 Hz is equal to 540 Hz.

What is bandwidth?

Bandwidth can be described as the difference between the upper and lower frequencies in a continuous band. Bandwidth is measured in hertz and refers to passband bandwidth or baseband bandwidth. Passband bandwidth can be described as the difference between the upper and lower cutoff frequencies of a signal spectrum.

Two different measures of relative bandwidth are in common use: fractional bandwidth and ratio bandwidth .

where and are the upper and lower frequency limits respectively of the given band.

Given the lower frequency = 60 Hz

The upper frequency of the signal = 600 Hz

Bandwidth = 600 - 60 = 540 Hz

Therefore, the bandwidth of a signal composed of frequencies from 60 Hz to 600 Hz is 540 Hz.
