Gold is metallic, with a yellow color when in a mass, but
when excellently separated it may be black, ruby, or purple. Your density
numbers have no units, so they are unusable.
If the numbers you give match to the densities of the given
metal in g/ml or kg/L, it should be gold.
Density = mass/volume, so:
96.5g/5ml = 19.3 g/ml. So the answer is 19.3 gold.
Answer:
A) Increases by a factor of 2
Explanation:
Kinetic energy can be defined as an energy possessed by an object or body due to its motion.
Mathematically, kinetic energy is given by the formula;
Where;
K.E represents kinetic energy measured in Joules.
M represents mass measured in kilograms.
V represents velocity measured in metres per seconds square.
Given that mass, m = 2m
Substituting into the equation, we have;
K.E = ½mv²
K.E = ½*2mv²
Cross-multiplying, we have;
2K.E = 2mv²
Hence, if the mass of an object increases by a factor 2, kinetic energy is increased by a factor of 2.
The magnet is at a gravitational force while the paper clip is at an applied force
Russian nesting dolls are an amazing comparison for the strongest magnet in the world, because the magnitis were inserted inside each other. The magnets would be adapted so they could be put together, Because they are closer, the coils of the magnet would be tougher. The magnets would be able to magnetize better.
I believe it’s the first one
