Answer:
It will float.
Explanation:
Hello.
In this case, given the width, length and height, we can compute the volume as follows:
Moreover, since the density is computed via the division of the mass by the volume:
We obtain:
In such a way, since the solid has a lower density than the water, we infer it will float.
Best regards.
Answer:
False
Explanation:
The inner planets are called terrestrial planets due to the surfaces are solid (similar to Earth)-made up of heavy metals, either have no moons or few moons.
The outer planets are called Jovian planets or gas giants because they are encased in gas. They all have rings with plenty of moons.
The equivalent of the Newton's second law for rotational motions is:
where
is the net torque acting on the object
is its moment of inertia
is the angular acceleration of the object.
Re-arranging the formula, we get
and since we know the net torque acting on the (vase+potter's wheel) system,
, and its angular acceleration,
, we can calculate the moment of inertia of the system:
Wave reflection occurs when waves reflect or rebound off of a surface. This is like an echo because the sound waves are reflected from a distant surface
Newton's third law of motion states that for any action, there is equal and opposite force. For a person standing on a floor, the action force is the weight and thus the floor must exert an opposite and equal reaction force equivalent in magnitude to the weight of the person.
In this regard, statement 3. is correct.
