Are you saying Santa invensted electricty...my childhood was a lie!!!!
Early stages of carbon monoxide poisoning is often confused with seasickness or intoxication.
This is so because some symptons of carbon monoxide (CO gas) poisoning are: irritated eyes, headache, nause, weakness and dizziness. As you can see those symptons are common to seasickness and intoxitation.
Carbon monoxide (CO gas) is colorless and odorless, so it may be difficult to detect the exposure to it before having some symptons of CO poisoning, but it is serious and can result in death. The victim shall be conducted to an open place promptly to receive fresh air and carried to a hospital to receive treatment urgently.
Archimedes' principle allows us to find that the reasons why the thrust is not written when a body is in the air is:
- The thrust of air is about 800 times less than the thrust of a fluid
- In general the other forces (weight, tension) are much greater than thrust
Archimedes' principle establishes that the thrust is equal to the weight of the dislodged liquid (fluid)
B = ρ g V
Where B is the thrust, ρ and V the density and volume of the fluid, respectively, g the acceleration due to gravity.
In the attachment you have a diagram of a system in equilibrium in air and water, we can see that in the two cases for a system in equilibrium
B -W = 0
B = W
Let's find the value of the thrust in each case and compare
Used the density
Suppose that the volume of the two bodies is the same
r
We can see that the thrust in air or other gas is about 800 times less than the thrust in liquids. This is the reason that in many problems the thrust is not written when the body is in the air.
In conclusion, using Archimedes' principle, we find that the reason why the healed thrust is not written for a body is in the air is:
- The thrust of air is about 800 times less than the thrust of a fluid
- In general the other forces (weight, tension) are much greater than thrust

The Milky Way Galaxy is thought to contain hundreds of millions of black holes. But only a few dozen have revealed themselves—through the x-ray glow of hot gases that surround them. Now, astronomers have found a “dark” black hole only 1000 light-years away from Earth—just down the road in galactic terms. It is the closest black hole to our planet ever found, in a star system that is visible to the naked eye. “They have good evidence,” says Todd Thompson, an astronomer at Ohio State University, Columbus. “I believe them.”
The invisible nature of most black holes frustrates astronomers, who can learn about this final stage of stellar evolution only from the few dozen that have been found heating up an “accretion disk”—swirling gas they gobble up. Recently, however, astronomers have found several naked, nonaccreting candidates, using a technique borrowed from exoplanet searches. Exoplanet hunters look for periodic shifts in the frequency of the light from stars as it moves toward and away from Earth.
Explanation:
Answer: Crystals differ in physical properties, i.e., in hardness, cleavage, optical properties, heat conductivity, and electrical conductivity.
These properties are important since they sometimes determine the use to which the crystals are put in industry.
hope this helps :)
