Answer:
The distance between the crest will decrease as the frequency of the waves increase.
To solve this problem we will use the two principles that are visible according to the phenomena described in the problem: Heat transfer by conductivity and Heat transfer by convection.
This thermal transfer will be equivalent and with it we can find the value asked.
<em>Note: We will assume that the temperature value at the plate surface is: 60 ° C (For the given value of 650 50)</em>
For Thermal Transfer by Conduction
Where,
k = Thermal conductivity
A = Cross-sectional Area
= Temperature of the bottom surface
= Temperature of the top surface
L = Length
Replacing we have that
For Thermal Transfer by Convection
Where,
h = Convection heat transfer coefficient
= Surrounding temperature
A = Surface Area
Replacing we have that
Since the rate of heat transfer by convection is equal to that given by conduction we have to:
It is stated that the typical values of forced convection of gases lies in the range of . The obtained value is reasonable for forced convection of air.
A bad posture can result in tight muscles. Flexibility is the capacity to move a joint though it's full range.
