Answer:
Refractive index
Heat capacity
Density
Explanation:
Properties that are used to identify materials are called intensive properties. These intensive properties are characteristic of the material and does not depend on the amount of material present.
Thus, if i want to identify whether the three bars are made of the same metal, i can look out for the following properties;
Refractive index
Heat capacity
Density
These properties are intensive properties thus they can be used to identify an unknown substance.
Answer:
d=m/v If v increases then the density decreases. Denominator get larger
Explanation:
If those 'x's' mean times, then your answer should be 0.01742919.
Fission is the splitting of an atom. In a nuclear reaction
Answer:
Explanation:
Of course Newton's three laws of motion are correct, because they were verified several hundred of years ago and they continue working today, for such systems. Science is accumulative. What modern physics has done is to constraint the range of validity of those laws.
Newtons first law of motion states that everybody continues in it rest or of uniform motion in a straight line unless an external force is applied on it.
Newtons second law of motion states that acceleration produced on a body by a force is directly proportional to the applied force and inversely proportional to the mass of body.
Newtons third law of motion states that to every action there is equal and opposite reaction.
