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.

An iron ball and an aluminum ball of mass 100 g each are heated to the same temperature and then cooled to a temperature of 20°C
Mekhanik [1.2K]
As the temperature changes and their masses are the same, heat lost by the balls is directly proportional to their specific heat values. The heat lost by the aluminum ball is higher implies aluminum has higher specific heat.

A horizontal spring with spring constant 85 n/m extends outward from a wall just above floor level. a 3.5 kg box sliding across
Rina8888 [55]

k = spring constant of the spring = 85 N/m

m = mass of the box sliding towards the spring = 3.5 kg

v = speed of box just before colliding with the spring = ?

x = compression the spring = 6.5 cm = 6.5 cm (1 m /100 cm) = 0.065 m

the kinetic energy of box just before colliding with the spring converts into the spring energy of the spring when it is fully compressed.

Using conservation of energy

Kinetic energy of spring before collision = spring energy of spring after compression

(0.5) m v² = (0.5) k x²

m v² = k x²

inserting the values

(3.5 kg) v² = (85 N/m) (0.065 m)²

v = 0.32 m/s

Tex, an 85.0 kilogram rodeo bull rider is thrown from the bull after a short ride. The 520. kilogram bull chases after Tex at 13
Julli [10]
The question above can be answered through using the concept of Conservation of Momentum which may be expressed as,
                 m1v1 + m2v2 = mTvT
where m1 and v1 are mass and initial velocity of Tex, 2s are that of the bull, and the Ts are the total. Then substituting,
                    (85 kg)(3 m/s) + (520 kg)(13 m/s) = (520 + 85)(vT)
The value of vT obtained from above equation is 11.6 m/s

A historical society is testing an old cannon. They
sveta [45]

Answer:

26.2 m/s

Explanation:

We can find the speed of the cannonball just by analyzing its vertical motion. In fact, the initial vertical velocity is

u_y = u sin \theta (1)

where u is the initial speed and \theta = 45.0^{\circ} is the angle of projection.

We can therefore use the following suvat equation for the vertical motion of the ball:

v_y = u_y + at

where v_y is the vertical velocity at time t, and a=g=-9.8 m/s^2 is the acceleration of gravity. The time of flight is 3.78 s, so we know that the ball reaches its maximum height at half this time:

t=\frac{3.78}{2}=1.89 s

And at the maximum height, the vertical velocity is zero:

v_y=0

Substituting these values, we find the initial vertical velocity:

u_y = v_y - at = 0-(-9.8)(1.89)=18.5 m/s

And using eq.(1) we now find the initial speed:

u=\frac{u_y}{sin \theta}=\frac{18.5}{sin 45.0^{\circ}}=26.2 m/s

Which shows the correct lens equation? The inverse of f equals the inverse of d Subscript o Baseline times the inverse of d Subs
musickatia [10]

Answer:

The inverse of f equals the inverse of d Subscript o Baseline plus the inverse of d Subscript I Baseline.

Explanation:

The lens equation shows the relation among focal length of the lens, image distance and object distance. It can be expressed as:

  \frac{1}{f} = \frac{1}{d_{o} } + \frac{1}{d_{I} }

where: f is the focal length of the lens, d_{o} is the object distance to the lens and d_{I} is the image distance to the lens.

The lens equation can be used to determine the unknown value among the variables f , d_{o} and d_{o}.
