Two circus performers rehearse a trick in which a ball and a dart collide. Horatio stands on a platform 9.8 m above the ground a

Answer:

Time = 0.55 s

Height = 8.3 m

Explanation:

The ball is dropped and therefore has an initial velocity of 0. Its acceleration, g, is directed downward in the same direction as its displacement, $h_b$ .

The dart is thrown up in which case acceleration, g, acts downward in an opposite direction to its displacement, $h_d$ . Both collide after travelling for a time period, t. Let the height of the dart from the ground at collision be $h_d$ and the distance travelled by the ball measured from the top be $h_b$ .

It follows that $h_d+h_b=9.8$ .

Applying the equation of motion to each body (h = v_0t + 0.5at^2),

Ball:

$h_b=0\times t + 0.5\times 9.8t^2$ (since $v_{b0} =0$ .)

$h_b=4.9t^2$

Dart:

$h_d=17.8\times t - 0.5\times9.8t^2$ (the acceleration is opposite to the displacement, hence the negative sign)

$h_d=17.8\times t - 4.9t^2$

But

$h_b+h_d =9.8$

$17.8\times t - 4.9t^2+4.9t^2 =9.8$

$17.8\times t = 9.8$

$t = 0.55$

The height of the collision is the height of the dart above the ground, $h_d$ .

$h_d=17.8\times t - 4.9t^2$

$h_d=17.8\times 0.55 - 4.9\times(0.55)^2$

$h_d=9.79 - 1.48225$

$h_d=8.3$

Use the paragraph to answer the question.

nadezda [96]

The characteristic of science that is best exemplified by the paragraph presented is "It is falsifiable and reproducible."

<h3>What is science?</h3>

Science can be mostly defined as a set of methods and principles that aim at objectively understanding and explaining the phenomena that occurs in the world.

These set of methods and principle lead to theories and laws that describe how a specific phenomenon occurs.

<h3>What does "It is falsifiable and reproducible"?</h3>

This is a basic principle that implies hypotheses about a specific phenomenon can be tested using experiments and this can lead to either the confirmation of the hypothesis or dispproved. Moreover, same experiments can be used and these will have similar results.

This principle matches the paragraph because the same experiment leads to same results. Moreover, previous ideas about a phenomenon were disproved.

Answer:

Spurious relationship

Explanation:

In statistics a spurious relationship is a correlated mathematical relationship of covariation between two variables or more which by themselves have no cause and effect relationship as a result of a coincidence or the existence of a third or confounding factor

The variables have covariation due to their correlation but they don't have a cause and effect relationship

An example of a spurious relationship is the increase in ice cream sales when there is an observed increase in the rate of drowning.
