Hello,

I have some questions:

1. Do you think the calculated moment of inertia is larger or smaller than the true moment of inertia? Explain.

for static moment of inertia I have:.0202kgm^2
for dynamic " ":.0195 kgm^2

In this case, it's smaller but I don't know why.

2. Is the percent difference in accord with your answer to #2? Give plausible explanations/causes to account for the difference. for the percent difference I got 3.6% which is small so it does agree with #2. I am not sure why there is a difference though.

3. The wheel could replace the pulley on newton's law's 2nd law. Try to rethink an answer to the question: "If the pully has a fairly large mass, how will the result of this experiment be affected? "

In Darwin’s day, many people swallowed the theory of spontaneous generation—that life arose from non-living matter. It was somewhat easier to believe because the cell’s structure was almost unknown.

But now that we see how complex the simplest cell is and any subtraction to that simplicity the cell would cease to exist. How does natural selection work when you're starting from nothing?

Once life has started I can see how natural selection works but before life? How?

Hey!!! I'm looking for quite simple experiments to do during my holidays. have any idea? Well, i don't want the childish stuff like making carbon dioxide from baking soda. Just suggest the interesting ones you have. We can share some investigations and perhaps take up a new research project.

Waiting for your reply.

How do you find the derivatives of the following:

F(Z1,Z2) = Z1^u*Z2^v

MRTS(Z1,Z2) = (uZ2/vZ1)

I once heard that if you apply saliva or salt water to a mosquito bite, it will help draw out the itch. Is that true and, if so, why?

OK, it's a little silly, but if you think about it it does bring up some interesting thoughts about how we think about evolution and family. I'm looking for a clever answer if you want 10 points.
