Responder:
12374550,527 N / m²
Explicación:
Dado que:
Número de tacos = 10
Área de cada montante = 0.01 in²
Peso total de la persona = 180 libras
Usando la relación:
Presión = Fuerza / Área
La fuerza ejercida es el producto de la masa y la aceleración debido a la gravedad.
Masa = 180 libras = 81,47 kg
Aceleración por gravedad = 9,8 m / s²
Área total = (número de montantes * Área por montante) = (10 * 0.01) = 0.1 pulg²
Conversión a m²:
0,1 pulg² = 6,452 * 10 ^ -5 m²
Por lo tanto,
Presión = (81,47 * 9,8) / (6,452 * 10 ^ -5)
Presión = 798.406 / 0.00006452
Presión = 12374550.527 N / m²
Answer:
UP
Explanation:
heat rises. That powers convection which is in the link
The numbers in front of a compound is called a subscript. It shows how many atoms of that specific element it is next two that is involved in the reaction or is in that compound.
The answer is then D.
Coefficient is found behind the compounds, the charges are written above.
Answer: Option (e) is the correct answer.
Explanation:
There are three types of kinetic energy which are vibrational, rotational and translational kinetic energy.
A plucked string on a guitar will produce sound and it represents vibrational kinetic energy.
The moving blades of a ceiling fan shows the rotation of blades and it represents rotational kinetic energy.
A spinning top also displays rotation therefore, it represents rotational kinetic energy.
A tuning fork struck on a rubber block will produce sound and it will vibrate. Therefore, it represents vibrational kinetic energy.
An apple falling from a tree shows that apple is linearly falls on the ground therefore, it represents translational kinetic energy.
Thus, we can conclude that an apple falling from a tree is the best example which represents translational kinetic energy.
