Answer:
<em>The internal energy change is 330.01 J</em>
Explanation:
Given
the initial volume = 5.75 L
the final volume = 1.23 L
is the external pressure = 1.00 atm
q the heat energy removed = -128 J (since is removed from the system)
expansion against a constant external pressure is an example of an irreversible pathway, here pressure in is greater than pressure out and can be obtained thus;
W = -ΔV
W = -1.00 x(1.23 - 5.75)
W = -1.00 x -4.52
W = 4.52 L atm
converting to joules we have
W = 4.52 L atm x 101.33 J/ L atm = 458.01 J
The internal energy change during compression can be calculated thus;
ΔU = q + W
ΔU = -128 J + 458.01 J
ΔU = 330.01 J
Therefore the internal energy change is 330.01 J
It's the instantaneous speed. Average speed would take all the different speeds from the whole ride in order to fine the median or middle speed.
The green band is coming from the thicker region of the bubble.
White light is made up of all colours, all wavelengths. If one of these colours is subtracted from white light (by interference, for instance) we see the complementary colour.
For example, if blue light is subtracted from white light, we see yellow. The skin of a bubble glistens with the complementary colours produced by interference.
If we were to look at a highly magnified portion of a soap bubble membrane, we would notice that light reflects off both the front (outside) and rear (inside) surfaces of the bubble, but the ray of light that reflects off the inside surface travels a longer distance than the ray which reflects from the outside surface.
When the rays recombine they can get "out of step" with each other and interfere. Given a certain thickness of the bubble wall, a certain wavelength will be cancelled and its complementary colour will be seen. Long wavelengths (red) need a thicker bubble wall to get out of step than short wavelengths (violet). When red is cancelled, it leaves a blue-green reflection.
As the bubble thins, yellow is cancelled out, leaving blue; then green is cancelled, leaving magenta; and finally blue is cancelled, leaving yellow. Eventually the bubble becomes so thin that cancellation occurs for all wavelengths and the bubble appears black against a black background.

Technology has affected almost every aspect of modern sports.
Answer: Option A
<u>Explanation:</u>
Modern sports consists of outdoor games and games related to having physical exercise of the body. But nowadays, technology had made the outdoor games as video games and these video games are so realistic to view that it makes the player addicted and attracted to the video games.
So in this technology, the player should use less or no physical strength to win a video games related to modern sports instead it is played on smart phones, laptops or other visible devices.
Thus, the environment of playing in a group and doing physical work for playing different games are mostly affected with rise in technology which produced realistic video games. Thus technology affects the aspects of modern sports.
