Answer:
Explanation:
Tides occur mainly in oceans because that is basically one huge body of water that is free to move all over the earth. Lakes and rivers do not cover enough area to have their water be moved significantly by gravity, or in other words, to have tides.
You have to take note of the prefix because it gives you a hint of its value with respect to the base value. The base value is ratio. When the prefix is deka, that means that 1 ration is equal to 0.1 dekaration according to the metric system. The conversion is as follows:
68 rations * 0.1 dekarations/1 ration = 6.8 dekarations
Answer:
The Sun is a main-sequence star, and, as such, generates its energy by nuclear fusion of hydrogen nuclei into helium. In its core, the Sun fuses 620 million metric tons of hydrogen and makes 616 million metric tons of helium each second.
Two vectors of unequal magnitude can never sum to zero. If they point along the same line, since their magnitudes are different, the sum will not be zero.
Answer:
a) its frequency
Explanation:
The color of visible light depends only on its frequency, not on the amplitude. In fact, the visible light spectrum can be classified into different colors according to the different frequencies:
Violet: 680-790 THz
Blue: 620-680 THz
Cyan: 600-620 THz
Green: 530-600 THz
Yellow: 510-530 THz
Orange: 480-510 THz
Red: 405-480 THz
And the color of the light has nothing to do with the amplitude of the wave. Therefore, the correct answer is
a) its frequency
