<span>The
temperature at which the vapor pressure of a liquid equals the
environmental pressure surrounding the liquid is best defined as:
Boling Point

The student's conclusion shows experimental bias
Just because most of nis classmates like puffed cereal ,it is inappropriate to conclude puffed cereal is better than oats cereal
The one that will change the velocity of a periodic wave is :
B. Changing the medium of the wave
Waves is always determined by the properties of the medium, which means that changing the medium will change the velocity of the wave
hope this helps
You have two possible ways to connect the springs: in parallel or in series.
The equivalent stiffness of three springs in parallel is given by:
k_eq = k₁ + k₂ + k₃
In order to keep this number the smallest possible, you need to take the three springs with smaller k:
k_eq_min = 3.5 + 6 + 8.5 = 18 N/m
The equivalent stiffness of three springs in series is given by:
1 / k_eq = 1 / <span>k₁ + 1 / k₂ + 1 / k₃
In order to get the smallest k_eq possible, 1 / k_eq must be the biggest possible, therefore you need to take again the three springs with smaller k:
k_eq = 1 / (</span>1 / <span>k₁ + 1 / k₂ + 1 / k₃)
= 1 / (1 / 3.5 + 1 / 6 + 1 / 8.5)
= 1.754 N/m
Therefore, in order to get the smallest equivalent stiffness, you need to connect the first three springs in series (one after the other).</span>
