Is it OK to eat fish everyday?
Government dietary guidelines recommend that people eat fish twice a week.
“For most individuals it’s fine to eat fish every day,” says Eric Rimm, professor of epidemiology and nutrition, in an August 30, 2015 article on Today.com, adding that “it’s certainly better to eat fish every day than to eat beef every day.”.
Can you touch mercury?
Mercury is a very toxic or poisonous substance that people can be exposed to in several ways. If it is swallowed, like from a broken thermometer, it mostly passes through your body and very little is absorbed. If you touch it, a small amount may pass through your skin, but not usually enough to harm you.
What is Newton’s 4th Law?
Newton’s Law of gravitation is called Newton’s fourth law. It states that every point mass attracts every other point mass by a force acting along the line intersecting both points. The force is proportional to the product of the two masses, and inversely proportional to the square of the distance between them.
Is Mercury a poison?
Health effects of mercury exposure Elemental and methylmercury are toxic to the central and peripheral nervous systems. The inhalation of mercury vapour can produce harmful effects on the nervous, digestive and immune systems, lungs and kidneys, and may be fatal.
Who invented anti gravity?
Thomas Townsend BrownThomas Townsend Brown. Thomas Townsend Brown (March 18, 1905 – October 27, 1985) was an American inventor whose research into odd electrical effects led him to believe he had discovered a connection between strong electric fields and gravity, a type of antigravity effect.
Can mercury be used for anti gravity?
It’s not anti gravity it’s magnetic levitation, a completely different phenomenon. It’s no more anti gravity than a helicopter, airplane or balloon. That does not mean it couldn’t be used as a means of propulsion. … It can’t work – mercury obeys gravity just like everything else, but it looks cute.
Is antimatter repelled by gravity?
As a new study shows, general relativity predicts that the gravitational interaction between matter and antimatter is mutually repulsive, and could potentially explain the observed expansion of the Universe without the need for dark energy.
Can we explain gravity?
However, if we are to be honest, we do not know what gravity “is” in any fundamental way – we only know how it behaves. Gravity is a force of attraction that exists between any two masses, any two bodies, any two particles. Gravity is not just the attraction between objects and the Earth.
Is gravity a theory or law?
This is a law because it describes the force but makes not attempt to explain how the force works. A theory is an explanation of a natural phenomenon. Einstein’s General Theory of Relativity explains how gravity works by describing gravity as the effect of curvature of four dimensional spacetime.
What does antimatter look like?
When you see antimatter depicted in science fiction movies, it’s usually some weird glowing gas in a special containment unit. Real antimatter looks just like regular matter. Anti-water, for example, would still be H2O and would have the same properties of water when reacting with other antimatter.
What is Mad Hatter’s Disease?
Erethism, also known as erethism mercurialis, mad hatter disease, or mad hatter syndrome, is a neurological disorder which affects the whole central nervous system, as well as a symptom complex, derived from mercury poisoning. … Mercury poisoning can also occur outside of occupational exposures including in the home.
Is gravity a real thing?
Gravity (from Latin gravitas, meaning ‘weight’), or gravitation, is a natural phenomenon by which all things with mass or energy—including planets, stars, galaxies, and even light—are brought toward (or gravitate toward) one another.
Can liquid mercury be magnetized?
A: At room temperature, the element mercury is not very magnetic at all. It has a very small, negative magnetic susceptibility, meaning that when you put mercury in a magnetic field, it magnetizes just a little tiny bit in the opposite direction.
Is negative gravity possible?
Although the equations cannot normally produce a “negative geometry”, it is possible to do so by using “negative mass”. … Both general relativity and Newtonian gravity appear to predict that negative mass would produce a repulsive gravitational field.
