Thermal equilibrium is a state in which all parts of a system are at the same temperature
Density = 2.7g/cm3
mass =8.1grams
from density =(mass)/volume
we can determine the volume of aluminium by simply changing the subject of the subject of the formula from density to volume
so we have
volume=mass/density
=(8.1grams)/(2.7g/cm3)
=3cm3
The magnitude of a vector represents its<u> </u><u>direction</u>. The phrase also refers to a quantity's mathematical or geometrical representation.
<h3 /><h3>What is a vector?</h3>
A vector is a quantity or phenomena with magnitude and direction that are independent of one another. The phrase also refers to a quantity's mathematical or geometrical representation.
If no vector can be written as a linear combination of the others, a set of vectors is said to be linearly independent.
If no vector in a collection of vectors can be written as a linear combination of the ones mentioned before it, the set is said to be linearly independent.
Hence, the magnitude of a vector represents its<u> </u><u>direction.</u><u> </u>

Answer:
w = 7.89 10⁻² rad/s
Explanation:
We will solve this exercise with the conservation of the annular moment, let's write it in two moments
Initial. With the insect in the center
L₀ = I w₀
End with the bug on the edge
= I w + w
The moments of inertia are
For a rod
I = 1/3 M L²
For the insect, taken as a particle
I = m L²
The system is formed by the rod and the insect, this is isolated, therefore the external torque is zero and the angular momentum is conserved
L₀ =
I w₀ = I w + w
w = I / (I + ) w₀
w = I / (I + m L²) w₀
Let's calculate
w = 1.43 10⁻³ / (1.43 10⁻³ + 5 10⁻³ 0.620²)² 0.185
w = 1.43 10⁻³ / 3.352 10³ 0.185
w = 7.89 10⁻² rad/s
The pressure value is given by the equation,
Where,
represents the density of the liquid
g= gravity
h= Heigth
A) For the measurement of the guage pressure we have the data data,
Replacing we get,
P_g = 12395Pa[/tex]
In order to find the Absolute pressure, we perform a sum between the atmospheric pressure and that of the Gauge,
B) The atmospheric pressure at sea level is 101325Pa, assuming ideal conditions, we will take this pressure for our calculation, so
