Answer:

Never Cry Wolf (1983)

Explanation:

1. Describe Tyler's scientific question.

<em>Were the wolves the main killers of the rapidly decreasing of caribou population?</em>

As he studies the population however, he discovers the wolves are not the main predators of the caribou at all, in fact the two species coexist peacefully. The real cause for the caribou population decline is discovered to be over hunting by the Eskimos and local hunters.

2. What was Tyler's hypothesis?

The first hypothesis that he addresses is the information he has received from the authorities and the decrease in population by the Wolves. However, as he approaches his behavior, he discovers that new hypotheses should be considered. This is due to the fact that he notes that the Wolves are not 'aggressive' as the compilations show, but also that they can live with the coribous in a peaceful manner.

This is why it poses three hypotheses:

- The wolves are not as aggressive as they seem, so a description of their lifestyle is necessary

- Wolves require another diet to survive in the winter in the absence of the caribous

- Wolves use a different sleep style from humans, so it is necessary to inquire if it is more effective than that of men.

3. Describe Tyler's experiment.

<em>Lifestyle assimilation experiment</em>

To understand the way of life of the wolves, Tyler tries to imitate him.

When approaching them, he establishes a store and begins his surveillance day and night.

<em>Wolf population experiment</em>

To gather more information about the wolf population and get an idea of the amount of wolves in the area, Mowat and a local Eskimo toured the Canadian Arctic to observe them.

<em>Diet experiment</em>

Upon observing the wolves, he discovered that the diet consisted of mice and not caribou. In order to demonstrate that this diet is possible, he decides to continue the same diet

4. What was the independent variable in Tyler's experiment?

The independent variable is mice, because you need to modify them to understand if they are enough or not for the diet.

5. What were the dependent variable(s)?

The dependent variable is proteins, minerals, carbohydrates and other foods that are part of a diet. In this case, the necessary to survive.

6. Describe the experiment's constants.

The constants are those variables that the researcher does not modify during his experiment. In this case the number of mice you eat per day.

7. What data was collected, recorded and analyzed?

For the particular case of the diet, he discovered that mice are enough to eat a diet. However, he also noted that the 10-minute leisurely sleep of wolves, during the day, is much more relaxing than the continuous 8 hours of sleep.

He also discovered that the population of wolves had decreased considerably.

8. What was Tyler's conclusion?

Indiscriminate hunting by the natives was decreasing the population of animals in the region.

9. How did Tyler publicize his results?

It is understood that the protagonist made a compilation of his results and returned to the 'civilization' shows his data obtained to the government entities for the respective action taking.

10. What could Tyler have done differently to increase the “validity” of the experiment?

The videographic and photographic record would have allowed to obtain many more details to understand the behavior of the animals.

11. Give a name to Tyler's Experiment.

Fun, food, and fear.

Sketch the circuit labeling the meter and bulb as two separate resistors connected in parallel to the voltage source. Then show
Ksenya-84 [330]

Answer:

Show attached picture

Explanation:

Let's call V the voltage provided by the battery in the circuit. M is the multimeter (let's call R_M its internal resistance) and R indicates the resistance of the light bulb.

We know that the meter's internal resistance is 1000 times higher than the bulb's resistance:

R_M = 1000 R (1)

Both  the meter and the bulb are connected in parallel to the battery, so they both have same potential difference at their terminals:

V_M = V_R

Using Ohm's law, V=RI, we can rewrite the previous equation as:

R_M I_M = R I_R

where

I_M is the current in the meter

I_R is the current in the bulb

Using (1), this equation becomes

(1000 R) I_M = R I_R \rightarrow I_M = \frac{I_R}{1000}

so, the current in the meter is 1000 times less than through the bulb.

A particle has a velocity of v→(t)=5.0ti^+t2j^−2.0t3k^m/s.
Makovka662 [10]

Answer:

a)a=5 i+2t j - 6\ t^2k

b)a=\dfrac{1}{24.83}(5i+4j-24k)\ m/s^2

Explanation:

Given that

v(t) = 5 t i + t² j - 2 t³ k

We know that acceleration a is given as

a=\dfrac{dv}{dt}

\dfrac{dv}{dt}=5 i+2t j - 6\ t^2k

a=5 i+2t j - 6\ t^2k

Therefore the acceleration function a will be

a=5 i+2t j - 6\ t^2k

The acceleration at t = 2 s

a= 5 i + 2 x 2 j - 6 x 2² k  m/s²

a=5 i + 4 j -24 k m/s²

The magnitude of the acceleration will be

a=\sqrt{5^2+4^2+24^2}\ m/s^2

a= 24.83 m/s²

The direction of the acceleration a is given as

a=\dfrac{1}{24.83}(5i+4j-24k)\ m/s^2

a)a=5 i+2t j - 6\ t^2k

b)a=\dfrac{1}{24.83}(5i+4j-24k)\ m/s^2

An organ pipe open at both ends has a radius of 4.0 cm and a length of 6.0 m. what is the frequency (in hz) of the third harmoni
Marysya12 [62]

When air is blown into the open pipe,

L = \frac{nλ}{2}

where nis any integral number 1,2,3,4 etc. and λ is the wavelength of the oscillation

⇒λ=\frac{2L} {n}

Note here that n=1 is for fundamental, n=2 is first harmonic and so on..

⇒ third harmonic will be n=4

Given L=6m, n=4, solving for λ we get:

λ=\frac{(2)*(6)}{4} =3m

Relationship of frequency(f), velocity of sound (c) and wavelength(λ) is:

c=f.λ Or f= \frac{c}{λ}

⇒f=\frac{344}{3}

≈115 Hz

dexar [7]

Answer:

t = 25 seconds

Explanation:

Given that,

Distance, d = 115 m

Initial speed, u = 4.2 m/s

Final speed, v = 5 m/s

We need to find the time taken in increasing the speed.

We know that,

Acceleration, a=\dfrac{v-u}{t} ....(1)

The third equation of kinematics is as follows :

v^2-u^2=2ad\\\\\text{Put the value of a in above equation}\\\\v^2-u^2=2\times \dfrac{v-u}{t}\times d\\\\\because (a^2-b^2)=(a-b)(a+b)\\\\(v-u)(v+u)=\dfrac{2\times (v-u)d}{t}\\\\t=\dfrac{2d}{v+u}\\\\\text{Putting all the values}\\\\t=\dfrac{2\times 115}{4.2+5}\\\\t=25\ s

Hence, it will take 25 seconds to increase the speed.
