Normally, the water pressure inside a pump is higher than the vapor pressure: in this case, at the interface between the liquid and the vapor, molecules from the liquid escapes into vapour form. Instead, when the pressure of the water becomes lower than the vapour pressure, molecules of vapour can go inside the water forming bubbles: this phenomenon is called
cavitation.
So, cavitation occurs when the pressure of the water becomes lower than the vapour pressure. In our problem, vapour pressure at
![15^{\circ}](https://tex.z-dn.net/?f=15%5E%7B%5Ccirc%7D)
is 1.706 kPa. Therefore, the lowest pressure that can exist in the pump without cavitation, at this temperature, is exactly this value: 1.706 kPa.
Color property of light would provide evidence for the idea that light is a wave
<h3><u>
Explanation:</u></h3>
The reality is that light manifests practices that are representative of both waves and particles. Young proposed that light of varying colors was formed of waves possessing various lengths, a basic theory that is popularly believed today. In contradiction, the particle theory advocates envisioned that several colors were obtained from particles holding either various masses or moving at various speeds.
All waves are perceived to experience refraction when they transpire from one means to another means. Light, similar to any wave, is apprehended to refract as it transfers from one medium into another medium.
Answer:
I think -7 N. Netforce is 3N-10N= -7N
Explanation:
Answer:
E
Explanation:
A vector is a physical quantity that has magnitude and direction while a scalar is a physical quantity that has magnitude only
*electric potential is a scalar quantity because it only has magnitude
*electric field and electric force are vector quantities because they have magnitude and direction
I think its 980.7
because 9.807 × 100
