Answer:
Archimedes Principle states that "any body completely or partially submerged in water is acted upon by an upthrust force which is equal to the magnitude of Weight of the body."
The frequency of wave B is half the frequency of wave A
Explanation:
The wavelength, the speed and the frequency of a wave are related by the wave equation:
where
v is the speed of the wave
f is its frequency
is its wavelength
The equation can also be rewritten as
In this problem, we have wave A with wavelength and speed v, so its frequency is
Then we have wave B, whose wavelength is twice that of wave A:
And its speed is the same; Therefore, its frequency is
So, the frequency of wave B is half that of wave A.

26) Longer feet allow for more more surface area on the ground. This allows for more stability and a less likely chance of falling over.
30) It will appear as if you are throwing the ball at the same speed the train is traveling.
When solar radiation reaches the Earth it quickly dissipates as most of the radiation and UV rays are blocked by ozone layer, but more radiation and UV rays are able to get through because of global warming.
