Calculating Force from Atmospheric Pressure on Sheila's Palm

AI Thread Summary
To calculate the force exerted on Sheila's palm by atmospheric pressure, the correct formula is F = P * A, where F is force, P is pressure, and A is area. Given that the area of Sheila's palm is 0.0017 m² and the atmospheric pressure is 100,000 Pa, the force can be calculated as F = 100,000 Pa * 0.0017 m². This results in a force of approximately 58823.53 N. The discussion clarifies the formula manipulation needed to derive the force from pressure and area. The final answer confirms the calculation of force based on the provided values.

ok my problem is that the question asks
The palm of Sheila's hand has an area of 0.0017m2.If the atmospheric pressure on the palm is 100,000 Pa, what force is being exerted on Sheila's palm by the atmosphere?

I know the formula is not P=F/A
I know you have to change the formula around but I don't know which way...
is it F=P/A?Or something esle?

Thanks for people that are answering!

Um...can't remember this formula off the top of my head, but if you start with P=F/A, you can't get it to F=P/A.
 
Pressure is F/A. Manipulating it gets you F=PA
 
P = F / A leads to

F = P*A
 
thanks...
i got the answers as 58823529.41
 
Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .
TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...
Thread 'A bead-mass oscillatory system problem'
I can't figure out how to find the velocity of the particle at 37 degrees. Basically the bead moves with velocity towards right let's call it v1. The particle moves with some velocity v2. In frame of the bead, the particle is performing circular motion. So v of particle wrt bead would be perpendicular to the string. But how would I find the velocity of particle in ground frame? I tried using vectors to figure it out and the angle is coming out to be extremely long. One equation is by work...
