Describe the graph of a bee’s motion if it leaves its hive in the positive direction, slows to visits a flower, then speeds up t
1 answer:
The definition of speed allows finding the answer for the shape of the speed graph of the bee is:
- The graph would take the shape of a. a v with the point down.
Velocity is defined by the change in position between time in a given interval
Where v is the velocity, Dx is the change in position and t is the time
In a graph of velocity versus time we have lines with a positive slope when the velocity increases, lines with a negative slope when the velocity decreases, and lines with a zero slope when the velocity remains constant.
In this case they tell us that the bee leaves the honeycomb and its speed decreases until it reaches the flower, therefore we have a graph with a negative slope.
After the bee returns to the honeycomb with an acceleration, therefore the speed increases, consequently the slope must be positive.
In the attachment we can see a schematic representation of the movement.
Let's analyze the different claims
- The graph would take the shape of a. a v with the point down.
True. This is similar to the attached graph
- The graph would take the shape of b. a v with the point up.
False. In motion it begins with a decrease in speed therefore the slope is negative
- The graph would take the shape of c. a parabola with the legs pointing up.
False. The graph is forming by lines
- The graph would take the shape of a parabola with the legs pointing down.
False the graph is formed by lines
In conclusion with the definition of speed we can find the result for the form of the speed graph of the bee is:
- The graph would take the shape of a. a v with the point down.

Explanation:
Joule -Thompson effect
Throttling phenomenon is called Joule -Thompson effect.We know that throttling is a process in which pressure energy will convert in to thermal energy.
Generally in throttling exit pressure is low as compare to inlet pressure but exit temperature maybe more or less or maybe remains constant depending upon flow or fluid flow through passes.
Now lets take Steady flow process
Let
Pressure and temperature at inlet and
Pressure and temperature at exit
We know that Joule -Thompson coefficient given as
Now from T-ds equation
dh=Tds=vdp
So
⇒
So Joule -Thompson coefficient
This is Joule -Thompson coefficient for all gas (real or ideal gas)
We know that for Ideal gas Pv=mRT
So by putting the values in
For ideal gas.
