Moment of inertia of single particle rotating in circle is I1 = 1/2 (m*r^2)
The value of the moment of inertia when the person is on the edge of the merry-go-round is I2=1/3 (m*L^2)
Moment of Inertia refers to:
- the quantity expressed by the body resisting angular acceleration.
- It the sum of the product of the mass of every particle with its square of a distance from the axis of rotation.
The moment of inertia of single particle rotating in a circle I1 = 1/2 (m*r^2)
here We note that the,
In the formula, r being the distance from the point particle to the axis of rotation and m being the mass of disk.
The value of the moment of inertia when the person is on the edge of the merry-go-round is determined with parallel-axis theorem:
I(edge) = I (center of mass) + md^2
d be the distance from an axis through the object’s center of mass to a new axis.
I2(edge) = 1/3 (m*L^2)

Answer:
C
Explanation:
There are two forces on the table: weight and normal force. Newton's second law:
∑F = ma
N - mg = 0
N = mg
N = (23.5 kg) (9.81 m/s²)
N = 230 N
A typical barometer measures the pressure of the location at where you're at. Once it displays the pressure, you can determine the height using the hydrostatic pressure. The equation is written below:
P = ρgh,
where
ρ is the density of air
g is the acceleration due to gravity
h is the height
Therefore, if the pressure increases, then the height also increases.
Answer:
P=3792.55 Pa
Explanation:
Para resolver este problema, vamos primero a hacer un dibujo de la situación (ver imagen adjunta).
En este caso, tanto el peso del aceite como el peso del agua están ejerciendo una presión sobre el fondo del recipiente, por lo que la presión total será la suma de ambas presiones. La presión está dada por la equación:
por lo que la presión total será:
y sustituímos (mucho cuidado de convertir las alturas a metros)
lo cual nos da como resultado:
P=3792.55 Pa
