Answer:
I am fairly certain it is A but i would wait for an expert to answer
Wavelength = (speed) / (frequency)
= (30 m/s) / (60/sec) =
= 0.5 meter .
Answer:
the correct answer is B
Explanation:
The kinetic model of the movement describes that the movement of the molecules increases with the increase of their internal energy, which in a macroscopic sample is reflected in an increase in the temperature of the sample.
The sample graph shows the function of temperature over time, which is why our kinetic model establishes that there is an increase in the movement of water molecules.
Consequently the correct answer is B
