Answer:
Hope this helps :)
Explanation:
In electrostatics, the electrical force between two charged objects is inversely related to the distance of separation between the two objects. Increasing the separation distance between objects decreases the force of attraction or repulsion between the objects.
Calculate wavelength with the wavelength equation.
Use the correct units.
Plug the known quantities into the equation and solve.
Use this equation to solve for speed or frequency.
Calculate wavelength with the energy equation.
Answer:
Absolute Pressure at depth h =
Explanation:
<u>Given:</u>
- Radius of the bubble at depth h,
- Radius of the bubble at the surface of the water,
- Acceleration due to gravity,
<u>Assumptions:</u>
- Atmospheric pressure,
- Density of water,
- Pressure at depth h =
- Pressure at the surface of water =
According to Ideal Gas Law,
where,
- P = pressure.
- V = volume.
- n = number of molecules.
- k = Boltzmann constant.
- T = absolute temperature.
For the given case, the temperature of the air bubble is constant. The number of molecules of the bubble also does not change, therefore,
PV = constant.
The pressure at the surface is equal to the atmospheric pressure,
The pressure at depth h is equal to sum of atmospheric pressure and the pressure of the water upto depth h,
Using these values,
The absolute temperature at that depth is given by
Answer:
I'm not sure if I have the right words for it, but it is most likely that all three rays will form a larger inverted image after they pass through the lens because the arrow is outside the focal point. The image will be outside of F2, like the arrow is outside of F1.
Explanation:
Due to the shape of the lens in the diagram, you can imagine 3 lines branching out from point Q. I've made a digital sketch about what will happen as they pass through. It's a little crude, but it still works. I hope this was helpful.
