Electromagnetism
How do atomic particles move in a uniform magnetic field?
They will create a spiral like pattern as they move through the field.
15,000,000 in scientific notation.
15 x 107
What is the weakest fundamental force?
gravity.
what is general inverse square law?
it is when a quantity like a force follows an inverse square law this means that the strength of the force varies decreases in proportion to the square of the distance from the object causeing the force.
what is newtens law of gravity
he said that every thing in the univerce that has mass exertid a gravitational force on every thing else in the univerce that had mass.
what does Ampere's law state?
a current carrying wire will produce a magnetic field.
0.00006 in scientific notation.
6 x 10-5
What happens in the bets decay process?
a neutron converts to a proton, an electron, and a neutrino, while a proton will convert to a neutron, a neutrino, and a positron.
if the distance is 1/5 what is the force
the force is 25 times stronger.
what is proof of einstiens law
the eclipse and the clocks.
what neat feature do ferrous metals have?
they can have mono-electron orbitals.( most metals have at least 2 electrons in their orbitals )
(3.8 x 109) x (9.2 x 10307) in scientific notation.
3.496 x 1041
What is the weak nuclear force?
One of the four fundamental forces, and is responsible for beta decay.
1/7 of a distance equals what force
49 times stronger.
how do moovies film seens were the actors are in zero gravity.
they are falling in a airplain with freefall.
how do you create an electromagnet?
By wrapping a copper wire around a ferrous metal core (iron, steal or nickel ) and running an electric current through the wire.
8 x 1027/2 x 1023 in scientific notation.
4 x 104
What is alpha decay?
protons and neutrons are ejected from the nucleus. these particles will then collide with other nuclei and more particles will be ejected, causing an uncontrollable cascade of other atoms being ripped apart.
if a force is 10 times weaker than what is the distance?
4 times further away.
how does being in an exelerated rocket feel simmalar to standing on the surface of a planet?(HOW DEOS EINSTIEN EXPLAIN THIS)
EINSTIEN explains this in thery of relativity the more massive an object is the more it warps the space around it.gravity is a curving of space based on the curviture of space time around a massive object.
What computer part uses electric fields?
The capacitor
suppose a distant planet had a mass of 16 x 1040 kg. how much force would a person who weighs 100 kg feel if they were standing 4 x 1012 meters from the planet center?
1 x 1019
what is nuclear decay?
a naturally occurring nuclear reaction in which an atom of a radioactive element spontaneously changes the composition of it's nucleus by the emission of particles and or electromagnetic radiation.
if a distance is 10 times futher away what is the force?
1/100th
according to Einstein gravity is what?
not a force
