Yes, even light rays can vary in wavelength and frequency, if the length of the ray is sorter, it becomes more energetic and has a higher frequency. If you're talking about a ray tracing diagram for lenses or mirrors, the length of the ray doesn't really matter unless you're finding the path length but there are some procedures for that too. Let me know if I missed what you were asking.
Answer:
The helium contained in the Sun's atmosphere was produced by fusion of hydrogen to helium in the Sun's core. Since planets including the sun where all formed at the same time, Jupiter's atmosphere also contains Helium.
Explanation:
1) the helium in the suns atmosphere from the original helium and any helium the sun has produced from the nuclear fusion of hydrogen.
2) the helium present in Jupiter's atmosphere came from the helium in the matter that produced our solar system.
3) the helium found in the suns core comes only from the nuclear fusion of hydrogen
Answer: all except 3, 5, and 6
Explanation: these 3 options are all positive effects. fewer extinctions would mean fewer loss of animal life, and a decrease in mining and water pollution would be less harmful to the environment
Answer:
Choice d. Approximately 
of the volume of this iceberg would be submerged.
Explanation:
Let 
denote the total volume of this iceberg. Let 
denote the volume of the portion that is under the liquid.
The mass of that iceberg would be 
. Let 
denote the gravitational field strength (
near the surface of the earth.) The weight of that iceberg would be: 
.
If the iceberg is going to be lifted out of the sea, it would take water with volume to fill the space that the iceberg has previously taken. The mass of that much sea water would be 
.
Archimedes' Principle suggests that the weight of that much water will be exactly equal to the buoyancy on the iceberg. By Archimedes' Principle:
.
The buoyancy on the iceberg should balance the weight of this iceberg. In other words:
.
Rearrange this equation to find the ratio between and :
.
In other words, of the volume of this iceberg would have been submerged for buoyancy to balance the weight of this iceberg.
Answer:
Newton's Second Law of Motion states that a force on an object is equal to the mass of the object multiplied by its acceleration (F=ma). ... When the punter kicks the ball, his foot exerts a force on the ball. The football then exerts an equal amount of force in the opposite direction on the kicker's foot.
