Answer:
21 m
Explanation:
La energía potencial de un cuerpo es la energía que posee el cuerpo en virtud de su posición.
La energía potencial se da como;
E = mgh
Dónde;
m = masa del cuerpo
g = aceleración por gravedad
h = altura del cuerpo
Aquí necesitamos obtener la altura del cuerpo.
h = E / mg
h = 10500/50 * 10
h = 21 m
The energies we encounter as noticeable light are a thin cut from the expansive range of electromagnetic radiation. Our tactile experience of light is resolved to a great extent by the light vitality's wavelength, which decides the tone of a shading, and its power, which impacts splendor. After light enters the eye through the student, whose size is managed by the iris, a camera-like focal point centers the beams by changing its ebb and flow, a procedure called convenience, on the retina.
Answer:
The photosynthetic organisms of the water can survive at a depth of 100 meters due to the presence of blue light.
Explanation:
There are two colors which are responsible for the process of photosynthesis. These two colors are red and blue. Red and blue light of solar radiation is absorbed and green light is reflected back by the green pigment called chlorophyll. So in the depth of 100 meters in the water, blue light is present so plants can make their own food during photosynthesis.
