I dont know the answer but I believe that is the formula
Respuesta:
Volumen = 0.0010126 m³
Ancho = 7,84 N
Explicación paso a paso:
Dado que:
Masa, m de alcohol = 0,8 kg
Densidad del alcohol, d = 790 kg / m³
Recordar :
Densidad, d = masa, m / volumen, v
Volumen = masa / densidad
Volumen = 0,8 kg / 790 kg / m³
Volumen = 0.0010126 m³
Peso, W = densidad * aceleración debido a la gravedad * volumen
Ancho = 790 * 9,8 * 0,0010126
W = 7.8395
Ancho = 7,84 N
Answer:
B. 5 hours
Step-by-step explanation:
If the train is going 60mph and we need to find out how long it will be until it is traveling 80mph then we have to do 80-60=20 to figure out how much the speed is changeing. Since every hour the speed increases by 4mph then we have to do how much the train is increasing divided by how much it increases per hour.
20÷4=5
Therefore it will take 5 hours
