Answer:
Velocity is how fast and in what direction it moves.
Explanation:
Answer:
The separation of the 2 points should be 50.0 meters.
Explanation:
According to Rayleigh's scattering criteria the angular separation between 2 points to be resolved equals

Applying the given values we get

thus the linear separation equals 
Applying the given values we get


The heat capacity is given by the expression:






When the
is measured in the calorimeter, we obtain a value, and since we know the mass of the material and we control the change in
, we can then determine the specific heat "C" by simply remplazing in the expression.
