Answer:
Pressure applied by the man= 285103.125
or 41.35 ![lb/in^{2}](https://tex.z-dn.net/?f=lb%2Fin%5E%7B2%7D)
Explanation:
Pressure is defined as the perpendicular force applied per unit area.
i.e. ![Pressure=\frac{Force}{Area}](https://tex.z-dn.net/?f=Pressure%3D%5Cfrac%7BForce%7D%7BArea%7D)
Now, ![Force= mg](https://tex.z-dn.net/?f=Force%3D%20mg)
where,
= mass of the body(man) = 93 kg
= acceleration due to gravity of Earth = 9.81 ![m/{s^{2}}](https://tex.z-dn.net/?f=m%2F%7Bs%5E%7B2%7D%7D)
covered is equal to the area of both stilts(a man generally stands on two feet)
therefore
![m^{2}](https://tex.z-dn.net/?f=m%5E%7B2%7D)
and putting in the values, we get,
![Pressure=\frac{93\times9.81}{2\times(0.04)^{2}}Nm^{-2}=285103.125Nm^{-2}](https://tex.z-dn.net/?f=Pressure%3D%5Cfrac%7B93%5Ctimes9.81%7D%7B2%5Ctimes%280.04%29%5E%7B2%7D%7DNm%5E%7B-2%7D%3D285103.125Nm%5E%7B-2%7D)
Now we need to convert to our required units:
![1Nm^{-2}=1Pa\\1Pa=0.000145038lb/in^{2}](https://tex.z-dn.net/?f=1Nm%5E%7B-2%7D%3D1Pa%5C%5C1Pa%3D0.000145038lb%2Fin%5E%7B2%7D)
(We can get the above result by individually converting kg to lb and meters to inches respectively)
Using the above relations we get,
![Pressure=285103.125Pa=0.000145038\times285103.125lb/in^{2}=41.35lb/in^{2}](https://tex.z-dn.net/?f=Pressure%3D285103.125Pa%3D0.000145038%5Ctimes285103.125lb%2Fin%5E%7B2%7D%3D41.35lb%2Fin%5E%7B2%7D)
Crossing over, or recombination, is the exchange of chromosome segments between nonsister chromatids in meiosis. Crossing over creates new combinations of genes in the gametes that are not found in either parent, contributing to genetic diversity.

Hello!!
Here we have a simple matter of conservation of energy. ME=PE+KE.
At point A we have PE=mgh and KE=1/2mv^2. At point A all we have is PE since the coaster isn’t rolling yet. But by conservation of energy, we know that it will have enough energy to roll down and get to and equal height on another hill. Providing we are neglecting friction and drag and resistance forces which we are in this case. So we can conclude that the KE will be greater at Point B since ME=PE+KE and for ME to remain the same and we know the PE is less on lower hill, so we can conclude that KE on lower hill is greater to keep ME the same and have conservation of energy.
Hope this helps you understand the concept!! Any questions please just ask!! Thank you so much!!
