<h3><u>Answer;</u></h3>

Dilute solution

One gram of salt in 100 liters of water could be considered a <em><u>dilute solution</u></em>.

<h3><u>Explanation</u>;</h3>
  • <em><u>A solution is a mixture that is composed of two or more substances. It is formed when one substance (solute) dissolves on another called solvent. </u></em>
  • Solutions are homogeneous mixtures as the substances in it are always in the same phase. <em><u>A solution may be concentrated or dilute depending on the amount of solute or solvent in the solution.</u></em>
  • <u>A dilute solution has more solvent that solute while a concentrated solution has more solute than the solvent. In this case, </u><em><u>a solution containing 1 g of slat which is the solute in a 100 liters of water is an example of dilute solution.</u></em>

Using kinematic reasoning, the answers for the changes that can cause crashes are:

we can manipulate

  • The speed of the vehicles, especially that of the second car
  • he traffic light change time
  • Change some condition of the pavement after the first vehicle passes

Autonomous systems are systems that take a series of signals from the outside, analyze them and carry out actions according to how to handle them.

In that case you have two cars one behind the other at a short distance a traffic light with a yellow light is approaching.

Some parameters can be modified to cause the crash:

  • The car in front accelerates to pass the traffic light, but the traffic light changed to red, in this case if the car behind also accelerated, there may not be enough distance to stop and crash.

  • You can change the traffic light to green whereby the first car continues its speed, but the traffic light time changes very quickly to red, whereby the first car stops, but the car behind cannot stop.

  • The car behind accelerates to also pass the yellow light, but turns red and the first one crashes to a stop.

  • We change some condition of the pavement after the first vehicle passes, for example wetting the pavement, which decreases the coefficient of friction, consequently the second vehicle does not have time to stop.

We can appreciate that if there is not a good and fast communication between the two vehicles, it is easy for them to crash.

In conclusion, using kinematic reasoning, the answers for the changes that can test shocks are found:

  • The second vehicle increases speed and the first must brake sharply

Two students conduct a study to investigate the relationship between forearm length and height. Maria measures the subjects in c
inn [45]

Answer:

r = 0.86

Explanation:

Correlation coefficients are the strength of the relationship between two variables.

Correlations can indicate anywhere between

  • 1 - for a strong positive relationship.
  • -1 - for a strong negative relationship.
  • 0 - for no relationship at all.

Looking at sample correlation coefficient formula which says

r_{xy} = S_{xy} ÷ (S_{x} × S_{y})

where S_{x} and S_{y} are the sample deviations and S_{xy} is the sample covariance, all of which will remain the same for Maria and John.

Hence, John's correlation will be approximately 0.86 since he would have approximately the same measurement as Maria's measurement when Maria's measurement is converted from centimeters to inches.

A 0.0450-kg golf ball initially at rest is given a speed of 25.0 m/s when a club strikes. If the club and ball are in contact fo
LuckyWell [14K]

Answer:

Average force, F = 562.5 N

Explanation:

Mass of the golf ball, m = 0.045 kg

Initially, it is at rest, u = 0

Final speed of the ball, v = 25 m/s

The club and the ball are in contact for, t=2\ ms=2\times 10^{-3}\ s

We need to find the average force acting on the ball. It can be calculated using the formula as :

F\times t=m(v-u)

F=m\dfrac{v-u}{t}

F=0.045\times \dfrac{25}{2\times 10^{-3}}  

F = 562.5 N

So, the average force acting on the ball is 562.5 N. Hence, this is the required solution.
