Answer:
physical science
earth science and life science
Answer:
The answer is "Choice C ".
Explanation:
The relationship between the E and V can be defined as follows:
Let,
When E=0
v is a constant value
Therefore, In the electric potential in a region is a constant value then the electric-field must be into zero that is everywhere in the given region, that's why in this question the "choice c" is correct.
Answer:
Explanation:
h = Planck's constant = 
c = Speed of light = 
E = Energy = 
Wavelength ejected is given by
The maximum wavelength in angstroms of the radiation that will eject electrons from the metal is
The best way in handling in this situation is that in order for the astronaut to be able to get back to the shuttle is that he or she should take an object from his or her tool belt and to be thrown out away from the shuttle. This will allow her to weight lightly and safely return to the shuttle and would be easier for his or her to do so.
Answer:
C. water is more dense and viscous
Explanation:
Rapid gas exchange can be accomplished more easily in air than in water because water is more dense and viscous.
Gases have the greatest ease of diffusion of their respective particles, as occurs in air, since their molecules have higher speeds and have more distance from each other than liquids.
The molecular diffusion rate in liquids is much less than in gases. The molecules of a liquid are very close (liquids are more dense and viscous) to each other compared to those of a gas, then the gas molecules hits with the molecules of the liquid with more frequency and this causes that the gas moves slower than in other gas (for example in air).
