The moment of inertia is the rotational analog of mass, and it is given by
the product of mass and the square of the distance from the axis.
- The moment of inertia changes as the position of the weight is changed, which indicates that; statement is incorrect
Reasons:
The weight on each arm that have adjustable positions can be considered as point masses.
The moment of inertia of a point mass is <em>I</em> = m·r²
Where;
m = The mass of the weight
r = The distance (position) from the center to which the weight is adjusted
Therefore;
The moment of inertia, <em>I </em>∝ r²
Which gives;
Doubling the distance from the center of rotation, increases the moment of inertia by factor of 4.
Therefore, the statement contradicts the relationship between the radius of rotation and moment of inertia.

<span>velocity is defined as the rate of change of displacement irrespective of the length of the path travelled while speed is the average rate of covering distance. but in the liming case where the instantaneous velocity is given as v=dx/dt where dx is the small displacement in a small interval dt, both the speed and velocity have the same magnitude and the direction of velocity is the direction of the tangent to the corresponding displacement-time curve.</span>
The answer is flight technology, satelite technology, and exploration technology.
The flight technology include advances in jet propulsion and navigation. Satelite have become more and more powerful and hecne communication with distant objects is increasing in efficiency. The emergence of AI robots in space exploration are reducing risks to humans in these deep ventures.
Answer:
ReCrystallization
Contact pressure causing grains to "grow" together.
It's a metamorphic process used to rearrange the atoms of the minerals in order to modify them in to the required form under the specific temperature and pressure. For example conversion of limestone into marble.
<em>Cementation:</em>
Precipitation of bonding agents between grains.
Cementation is the process in which the minerals in the form of fluid fills in spaces between the grains and binds them together upon crystallizing.
<em>Compaction:</em>
Increase in density due to weight of overburden.
Compaction as it's name indicate is the compaction of the sediments due to the heavy weight of the rocks which reduce their size and increase their density.
I'd say C to avoid situations in which alcohol is present and remain alcohol free
Refusal skills help people, most likely children it helps them avoid participating in risky behaviors and choices. such like alcohol in this case
Refusal skills Helps them resist peer pressure and help them make right choices
Hope that helps alrighty bye now!
