Answer: In metals, some of the electrons (often one per atom) are not stuck to individual atoms but flow freely among the atoms. ... Those are the same factors that determine how well the metal conducts electricity. Therefore the more electricity an object can conduct the better it can conduct heat.
Explanation:
Natural length of a spring is . The spring is streched by . The resultant energy of the spring is .
The potential energy of an ideal spring with spring constant and elongation is given by .
So, in the current problem, the natural length of the spring is not required to find the spring constant .
∴ The spring constant of the spring =
Answer:
resultant vector
the answer is the resultant vector
Answer:

Explanation:
The pictures below explains it all in the calculation and i hope it helps you
We can find the momentum of the rock by using De Broglie's relationship:
where
p is the momentum
h is the Planck constant
is the De Broglie's wavelength
By using
, we find
The momentum of the rock is
where
is the mass and v is its velocity. Rearranging the equation, we find the speed of the rock:
