Because the particles of a solid are not free to move,
no matter how hot and buoyant they become.
Answer: It should be A or the very left red circle that you can click on
Explanation: Because when the wind is moving downward and the earth is spinning the spot the wind ends up will never be directly down from where it was to begin with
Answer:
There is no gravity in outer space so how will any object fall in the first place
Also the principle of terminal velocity is limited to free fall where the acceleration is equal to the gravity of the planet
Answer:
There are 2.71x10⁴ wavelengths between the source and the screen.
Explanation:
The number of wavelengths (N) can be calculated as follows:
Where:
: is the distance in glass = 2.25 mm
: is the distance in air = 1.50 cm - 0.225 cm = 1.275 cm
: is the wavelength in glass
: is the wavelength in air = 620 nm
To find the wavelength in glass we need to use the following equation:
Where:
: is the refraction index of glass = 1.80
: is the refraction index of air = 1
Hence, the number of wavelengths is:
Therefore, there are 2.71x10⁴ wavelengths between the source and the screen.
I hope it helps you!
