Answer:
Add an arrow above the symbol p to show it is a vector. Sometimes it is italicized in textbooks.
Explanation:
Answer:
Refractive index of liquid C > Refractive index of liquid B > Refractive index of liquid A
Explanation:
Let the depth of each section is h.
That means the real depth for each section is h.
Apparent depth is liquid A is 7 cm.
Apparent depth in liquid B is 6 cm.
Apparent depth in liquid C is 5 cm.
by the formula of the refractive index
n = real depth / apparent depth
where, n is the refractive index of the liquid.
For liquid A:
.... (1)
For liquid B:
..... (2)
For liquid C:
..... (3)
By comparing all the three equations
nc > nB > nA
Refractive index of liquid C > Refractive index of liquid B > Refractive index of liquid A
Answer:
Distancia = 50.04 metros
Explanation:
Dados los siguientes datos;
Velocidad = 10 km/h
Tiempo = 18 segundos
Para encontrar la distancia;
Conversión:
10 km/h = 10 * 1000/3600 = 2.78 m/s
Distancia = velocidad * tiempo
Distancia = 2.78 * 18
Distancia = 50.04 metros
Por lo tanto, el tren viajaría 50.04 metros antes de detenerse por completo.
