Between noon and 2 pm, the amount of water in the rain gauge decreased.
This can be caused by evaporation, which turns water into water vapor.
Precipitation would increase the amount of rain water in the gauges, not decrease it.
Condensation occurs after evaporation but wouldn't decrease the water in the gauges by itself.
Runoff is when water on land drains into water sources such as lakes, rivers, oceans, etc.
So the answer is A. evaporation.
I think it is d. I think but I don't know for a fact.
I believe the correct answer is A, Wave 1 has a longer wavelength and a higher amplitude than wave 2. Both A and B are transverse wave, therefore, the wavelength is the distance between two successful crest (highest point) or two successful trough (lowest point). In this case, wave 1 has a longer wavelength than wave 2. Amplitude is the maximum displacement of particles in a wave on either side from the equilibrium point. From the diagram wave 1 as a higher amplitude compared to wave 2.
The law you need is :
lets call the constant c = 4pi*epsilon naught*r2.
where r is radius ( or seperation of the charges). epsilon naught is a constant of about 8.85*10^-12 or something like that. and 4 pi is just 4 times pi.
the actual equation is
FORCE= (q1*q2)/c
Answer:
This means that the mass of one mole of aluminium atoms will be 26.982 g . As you know, one mole of any element contains exactly 6.022⋅1023 atoms of that element. This means that if you know how many moles of aluminium you have in 4.55 g , you can use Avogadro's number to find the number of atoms.
