Answer:
m* 8.0 kg*m²
Explanation:
Rotational inertia of a set of discrete masses (considered point masses), regarding an axis passing through a given point, is just the sum of the products of each mass times the distance to the point of interest.
In the attached picture, neglecting the masses of the rods joining the masses, and taking into account that all masses are equal each other, being equal to m kg, we can write the following equation:
I = m₁*r₁² + m₂*r₂² + m₃*r₃² + m₄*r₄²,
⇒ I = m kg*0 +m kg*2 m² +m kg*2m² + mkg*4m²
⇒ I = m*8 kg*m²
I would say the correct answer is the third option. The area of the Earth that is most similar to the Sun's convection zone would be the mantle. The convection zone of the sun is its outermost layer where heat transfer by convection happens which is similar to the Earth's mantle.
Explanation:Watt=NM/s=J/s=kgm²/s³=hP
Answer :B,kgm²/s³
If you float a piece of wood in a container half-full of water that rests on a weighing scale, the weight reading on the scale will increase.
<h3>What is Buoyancy?</h3>
Buoyancy is the force through your fluids or total or submerged bodies. Also known as Archimedes' theorem. The fluid of the direction on the body produces a resultant force but with the direction of the weight, with the opposite direction, upwards.
All material submerged in a liquid under the action of buoyancy, for this reason we have that the value on the scale will be increased with a system of a wood floating in water.
