Answer:
The length of the rod for the condition on the question to be met is 
Explanation:
The Diagram for this question is gotten from the first uploaded image
From the question we are told that
The mass of the rod is 
The mass of each small bodies is 
The moment of inertia of the three-body system with respect to the described axis is 
The length of the rod is L
Generally the moment of inertia of this three-body system with respect to the described axis can be mathematically represented as
Where 
is the moment of inertia of the rod about the describe axis which is mathematically represented as
And 
the moment of inertia of the two small bodies which (from the diagram can be assumed as two small spheres) can be mathematically represented as
![I_m = m * [\frac{L} {2} ]^2 = m* \frac{L^2}{4}](https://tex.z-dn.net/?f=I_m%20%20%3D%20%20%20m%20%2A%20%5B%5Cfrac%7BL%7D%20%7B2%7D%20%5D%5E2%20%3D%20%20m%2A%20%20%5Cfrac%7BL%5E2%7D%7B4%7D)
Thus 
Hence
=> ![I = [\frac{M}{12} + \frac{m}{2}] L^2](https://tex.z-dn.net/?f=I%20%20%3D%20%20%20%20%5B%5Cfrac%7BM%7D%7B12%7D%20%20%2B%20%5Cfrac%7Bm%7D%7B2%7D%5D%20L%5E2)
substituting vales we have
![0.929 = [\frac{3.41}{12} + \frac{0.249}{2}] L^2](https://tex.z-dn.net/?f=0.929%20%20%20%3D%20%20%20%20%5B%5Cfrac%7B3.41%7D%7B12%7D%20%20%2B%20%5Cfrac%7B0.249%7D%7B2%7D%5D%20L%5E2)
Answer:
False
Explanation:
No. The buoyant force on an object is the portion of its weight that appears to vanish
when the object is in any fluid (could be either a liquid or a gas).
If the object happens to float in a particular fluid, then the buoyant force at that moment
is equal to the object's weight.
Notice that the buoyant force on an object will be different in different fluids.
Answer:
Herpetology is the branch of zoology concerned with reptiles and amphibians.
Answer:
2 seconds
Explanation:
if a ball travels 1/2 meter per second, and there's 2 halfs in a whole, 1/2 meter per second x 2 halfs in a whole meter is 2 seconds to travel a meter
