Answer:
If we put pressure on a solid or a liquid, there is essentially no change in volume. ... The kinetic-molecular theory explains why gases are more compressible than either liquids or solids. Gases are compressible because most of the volume of a gas is composed of the large amounts of empty space between the gas particles.

Answer:
= 0.55 m
Explanation:
A standing wave is characterized by anti-nodes and nodes.
Antinodes are points on a standing wave at maximum amplitude, while nodes are points on the standing wave that are stationary and have zero amplitude.
The distance between two adjacent nodes or two adjacent anti-nodes is equivalent to half the wavelength.
Therefore, in this case the half wavelength is 27.5 cm.
Thus, wavelength = 27.5 × 2
= 55 cm
<u>= 0.55 m</u>
Answer:
![a=-0.33\ m/s^2](https://tex.z-dn.net/?f=a%3D-0.33%5C%20m%2Fs%5E2)
Explanation:
<u>Accelerated Motion</u>
The acceleration of a moving body is defined as the relation of change of speed (or velocity in vector form) with the time taken. The formula is given by
![\displaystyle a=\frac{\Delta v}{t}](https://tex.z-dn.net/?f=%5Cdisplaystyle%20a%3D%5Cfrac%7B%5CDelta%20v%7D%7Bt%7D)
Or, equivalently
![\displaystyle a=\frac{v_f-v_o}{t}](https://tex.z-dn.net/?f=%5Cdisplaystyle%20a%3D%5Cfrac%7Bv_f-v_o%7D%7Bt%7D)
Where vf and vo are the final and initial speeds respectively. The problem gives us these values: v0 = 3 m/s, vf = 1 m/s, t = 3 seconds. Computing a
![\displaystyle a=\frac{1-3}{3}=-0.33\ m/s^2](https://tex.z-dn.net/?f=%5Cdisplaystyle%20a%3D%5Cfrac%7B1-3%7D%7B3%7D%3D-0.33%5C%20m%2Fs%5E2)
The negative sing of a indicates there is deceleration or decreasing speed
The second option is the correct one. m/s^2
Good Morning, how are you?
Your answer is C. The moon orbits and rotates the same, so we NEVER see the far side of the moon from earth :)
Have a great day :)
