Two students grab a slinky and start waving it up and down. A third student counts the number of waves that pass by every second
and measures the distance between the wave peaks. This data is recorded and a graph is made to show the results.
In looking at the graph, what wave property is remaining constant over the experiment?

Answer:
The number of free electrons per cubic meter is
Explanation:
It is given that,
The number of free electrons per cubic meter is, 1.3
Electrical conductivity of metal,
Density of metal,
Atomic weight, A = 107.87 g/mol
Let n is the number of free electrons per cubic meter such that,
Where
is the density of silver atom
is the Avogadro number
A is the atomic weight of silver
or
Hence, this is the required solution.
Answer:
t = 4 s
Explanation:
As we know that the particle A starts from Rest with constant acceleration
So the distance moved by the particle in given time "t"
Now we know that B moves with constant speed so in the same time B will move to another distance
now we know that B is already 349 cm down the track
so if A and B will meet after time "t"
then in that case
on solving above kinematics equation we have
Let the bigger sphere be sphere 1 and the let the smaller sphere be sphere 2. Rest of the answer is in the picture.
