If the first thing that the goslings saw was a dog, they would have followed the dog as a mother.
Imprinting refers to the process of training an animal to bond with anything it sees after birth even if it is not its real mother. Lorenz first achieved imprinting in 1935 using geese which followed him as their mother shortly after they were born.
If the geese were exposed to a dog, they could also have seen the dog as their mother and followed it accordingly shortly after birth.

Answer:
The vapor pressure of cyclohexane at 81.0°C is 101325 Pa.
Explanation:
Given that,
Boiling point = 81.0°C
Atmospheric pressure :
Atmospheric pressure is the force per unit area exerted by the weight of the atmosphere.
The value of atmospheric pressure is
Vapor pressure :
Vapor pressure is equal to the atmospheric pressure.
Hence, The vapor pressure of cyclohexane at 81.0°C is 101325 Pa.

In finding the distance that covers we simply add the three km which is
12 + 4 + 1 = 17km
17 km is the distance they cover.
We are going to use the displacement formula which is
d = vt + 1/2 at^2
d = 11.7 km
11.7 is the displacement
Ответ:
Пояснение:
Используя уравнение движения S = ut + 1 / 2at², где;
U - начальная скорость = 15 м / с
а - ускорение
s - пройденное расстояние = 20м
t - время = 15 секунд
подставляем в формулу заданные параметры
20 = 15 (15) + 1 / 2a (15) ²
20 = 225 + 225a / 2
20 = 225 + 112,5a
20-225 = 112,5a
-205 = 112,5a
а = -205 / 112,5
а = -1,82
Отсюда ускорение -1,82
