Answer:
A
Explanation:
According to law of conservation of energy:
Mass (or energy) can neither be created nor destroyed but they can be changed into different forms.
As there is a lid on the bucket there is no evaporation happening, hence the mass will remain same.
Answer:
cycling of water in and out of the atmosphere.

Answer:
Explanation:
The frequency of an electromagnetic wave is given by
where
is the speed of light
is the wavelength
For the light wave in this problem, the wavelength is
So by using the equation above, we find its frequency:
The frequency of light can be found by using the formula f = c ÷ λ, where c is the speed of light and λ is the wavelength. By substituting these values into the formula, you can calculate the frequency of light with a given wavelength.
When you are given the wavelength of light and asked to find its frequency, you would use the formula c = fλ, where c is the speed of light (3.00 x 10⁸ m/s in vacuum), f is the frequency, and λ is the wavelength. To find the frequency, we rearrange this formula to get f = c ÷ λ. Given the wavelength λ = 6.33 x 10^-7 m, we can substitute these values into the rearranged formula to find the frequency:
f = (3.00 x 10⁸ m/s) ÷ (6.33 x 10^-7 m)
By calculating the above equation, you will find the frequency of the light with the given wavelength.
