What are the seasonal changes in the weasel in florida and the weasel in wyoming

1 answer:

7 0

Winter weasels, also called ermines or short-tailed weasels, have coats that turn from light brown to white in the winter. The color change begins at their stomachs and works its way outward, occurring in both spring and fall. Other species, like the long-tailed weasel, may turn at least partially white as well.

The length of daylight, not temperature, prompts the color change. As a result, weasels in winter may be stark white against a brown landscape before snow starts to fall. During warmer winters, this makes them easy prey for larger predators such as foxes, martens, and badgers.

Answer:

The probability of an incorrect report is found to be 0.03 or 3%.

Explanation:

We will get an incorrect report in both the cases of false alarm or missing excessive radiation. Since, both are mutually exclusive events. Therefore, the probability of both events to occur simultaneously will be 0. Thus, the probability of an incorrect report will be the sum of the probability of false alarm and the probability of a missing radiation.

P (False Alarm) = 0.02

P (Missing Radiation) = 0.01

P(Incorrect Report) = P (False Alarm) + P(Missing Radiation)

P (Incorrect Report) = 0.02 +0.01

P(Incorrect Report) = 0.03 = 3%

An eagle is flying horizontally at a speed of 4.10 m/s when the fish in her talons wiggles loose and falls into the lake 6.20 m

Sonbull [250]

Answer:

V=11.74m/s, 69.59°

Explanation:

From newtons equation of motion ,we know that

V^2 = u^2+2gh

for the rt

For the vertical component of the speed

Vy^2=V0^2+ 2gh

Vy= the final speed in the vertical axis

V0= initial speed, 0m/s

g= acceleration due to gravity 9.81m/s

h=height/distance between the eagle and the lake

Vy^2= 2*9.81*6.2

Vy =√121.644

Vy=11.02m/s

The resultant speed will be

V=(Vy^2+Vx^2)^0.5

V=(11.02^2+4.1^2)^0.5

V=137.7241^0.5

V=11.74m/s

Direction

Tan^-1(11.02/4.1)

β=69.59°

V=11.74m/s, 69.59°

Answer =11.74m/s, b°

When a car's starter is in use, it draws a large current. The car's lights draw much less current. As a certain car is starting,

ad-work [718]

Answer:

EMF = 11.35 V

R = 0.031Ω

Explanation:

To find the battery's EMF and the internal resistance we need to use Ohm's law:

$V = IR$

Where:

V: is the voltage

I: is the current

R is the resistance

We have:

The current through the battery is 64.2 A and the potential difference across the battery terminals is 9.36 V:

$\epsilon = V + IR$

$\epsilon = 9.36 V + 64.2A*R$ (1)

When only the car's lights are used, the current through the battery is 1.96 A and the terminal potential difference is 11.3 V:

$\epsilon = 11.3 V + 1.96A*R$ (2)

By solving equation (1) and (2) for R we have:

$9.36 V + 64.2A*R = 11.3 V + 1.96A*R$

$R = \frac{1.94 V}{62.24A} = 0.031 \Omega$

Hence, the internal resistance is 0.031 Ω.

Now, by entering R into equation (1) we can find the battery's EMF:

$\epsilon = 9.36 V + 64.2A*0.031 \Omega$

$\epsilon = 11.35 V$

Therefore, the battery's EMF is 11.35 V.

I hope it helps you!
