Explain imprinting in relation to Lorenz's geese. What would most likely have happened if the first thing the goslings saw was a

iragen [17]

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.

The speed of light is 3.0 x 108 m/s. How far does light travel in one day? Remember that you should first convert the day into s

Anna35 [415]

Answer:

$2.59\times 10^{13}\ m$

Explanation:

The speed of light is 3.0 x 10⁸ m/s

We need to find the distance traveled by it in one day.

1 day = 24 hours

1 day = 24 × 3600 seconds

= 86400 s

Now, using the formula of speed to find the distance covered as follows :

$d=v\times t$

Putting all the values, we get :

$d=3\times 10^8\ m/s\times 86400\ s\\\\d=2.59\times 10^{13}\ m$

Hence, light will cover $2.59\times 10^{13}\ m$ of distance in one day.

Can we use the traditional methods of measurement? Are they reliable? If not why?

Reil [10]

Answer:

Traditional methods of measurement involve methods like measurement using the arm, foot or hand span of a particular person which can and does varies form person to person and hence can't be reliable while the standard methods have a fixed standard value which is universal and same for everybody and every place and ..

The magnitude of the Poynting vector of a planar electromagnetic wave has an average value of 0.939 W/m2. The wave is incident u

Hatshy [7]

Answer:

The total energy is $T = 169.02 \ J$

Explanation:

From the question we are told that

The Poynting vector (energy flux ) is $k = 0.939 \ W/m^2$

The length of the rectangle is $l = 1.5 \ m$

The width of the rectangle is $w = 2.0 \ m$

The time taken is $t = 1 \ minute = 60 \ s$

The total electromagnetic energy falls on the area is mathematically represented as

$T = k * A * t$

Where A is the area of the rectangle which is mathematically represented as

$A= l * w$

substituting values

$A= 2 * 1.5$

$A= 3 \ m^2$

substituting values

$T = 0.939 * 3 * 60$

$T = 169.02 \ J$
