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:
2.4m/s towards the bowling pins
Explanation:
Given parameters:
Mass of the ball = 6.6kg
Momentum of the ball = 15.9kgm/s
Unknown:
Speed of the ball = ?
Solution:
The momentum is the amount of motion a body posses;
Momentum = mas x velocity
Insert the parameters and solve;
15.9 = 6.6 x velocity
velocity = 2.4m/s towards the bowling pins
1. Always be the bigger person
2. Violence is never the answer
3. Don’t fight fire with fire
Explanation:
Earwax helps to protect your ears from infection so if you like chewing gum, this helps in removing the wax. But this might not happen at your young age. So if you grow and still likes chewing gum it will remove the wax completely thereby leading to loss on hearing
Answer:
Radio waves are used for communications and radar. Microwaves are used to cook your food. Infrared waves are used in remote controls and are emitted from all warm objects, allowing them to be used to create heat-sensitive cameras.
Explanation:
Basically electromagnetic waves can be found in your everyday life.
