Kinetic energy is the type of energy that object obtains when being in motion. therefore Kinetic energy is the energy an object has due to it's movement!
Motion, I believe.
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
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 ?
Choose each that apply Which ones of the following are designed to interrupt the current flow of electricity when unsafe conditions arise
•gfcis(ground fault circuit interrupters
This is an automatic device designed for stopping the flow of current in an electric circuit as a safety measure.
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?
3. What is the bandwidth of a signal composed of frequencies from 60 Hz to 600 Hz?
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.

How could sea level rise affect our lives here in the Bay Area?
Well, day-to-day life in San Francisco, San Rafael, San Mateo, Oakland, Hayward, Redwood City, Union City, Fremont, Palo Alto, Milpitas, Mountain View, Cupertino, and even Santa Clara and San Jose would probably be pretty different if those places were all under water.
