Answer:
Oppositely charged particles attract each other, while like particles repel one another. Electrons are kept in the orbit around the nucleus by the electromagnetic force, because the nucleus in the center of the atom is positively charged and attracts the negatively charged electrons.
Explanation:
Answer:
Specific heat
Explanation:
The specific heat is the amount of heat, that is energy in transfer to or from a thermodynamic system, required to raise the temperature of 1 g of substance by one degree Celsius or one Kelvin, since one degree on the Celsius scale is equal to one Kelvin.
Answer:
Newton's first law of Inertia.
Explanation:
This explains how a magician is able to remove a tablecloth from under dishes and glasses on the table without disturbing them. Because of the mass of the object, it remains in inertia. The Tablecloth, in this trick, is slippery so that it does not have any real friction with glasses and dishes.
Answer:
Explanation:
NEWTON'S FIRST LAW OF MOTION:
a body continues its state of rest or of uniform motion in a straight line provided no net force acts on it. Fnet=0
NEWTON'S SECOND LAW OF MOTION:
when a net force acts on a body it produces acceleration in the body which is directly proportional to the magnitude of the net force and inversely to the mass of the body.F=ma
NEWTON'S THIRD LAW OF MOTION:
to every action there is always an equal but opposite reaction.
Answer:
if you are asking for static friction the answer is <u>372N</u>
Explanation
friction static=normal force x coefficient of static friction
and normal force is equal to weight of a body
so static friction = 600N x 0.62= 372N
