Answer:

The answer is C

Explanation:

Precision generally means been accurate (and can be loosely interpreted to mean been exact). Length is averagely measured in meters. However, in order to get the actual length of a substance using a tape, millimeters give the most accurate length (of all the options) as it provides the length to the smallest details (of all the options provided). The illustration below shows the relationship between millimeters and the rest of the options.

while 1 kilometer = 1000 meters

1 meter = 100 centimeters

1 centimeter = 10 millimeters

From the relationship above, millimeters is clearly the most precise of all the options provided.

A group of students are measuring how the acceleration of a mass will change when it is acted

Virty [35]

The scatter plot that shows a positive correlation between force and acceleration.

<h3>What is the relationship between acceleration of an object and the applied force?</h3>

The acceleration of an object is the change in velocity with time.

Acceleration = change in velocity/time

Force is defined as an agent which causes a change in the motion or state of rest of a body.

According to Newton's law of motion, the rate of change of velocity of an object is directly proportional to the applied force and takes place in the direction of the applied force.

Force and acceleration have a positive correlation.

Therefore, the scatter plot which will most closely match the measurements that the students will obtain is that which shows a positive correlation between force and acceleration.

In conclusion, acceleration of a object is proportional to the applied force.

To make a 1.0L dilute of 0.5M from a stock solution of 12M, how much solution will be needed?

Cerrena [4.2K]

Answer:

$V_{concentrated}=0.042L=4.2mL$

Explanation:

Hello,

In this case, since in a dilution process the moles of the solute must remain unchanged, we use the volumes and molarities as shown below:

$M_{diluted}V_{diluted}=M_{concentrated}V_{concentrated}$

Clearly, the concentrated solution is 12M and the diluted solution is 0.5 M, thus, the volume of the concentrated solution we should take is:

$V_{concentrated}=\frac{M_{diluted}V_{diluted}}{M_{concentrated}} =\frac{0.5M*1.0L}{12M}\\ \\V_{concentrated}=0.042L=4.2mL$

Best regards.

bio 102 Wildfire is a problem throughout the world because of high levels of _______ in the atmosphere Group of answer choices m

Bas_tet [7]

<h2>Carbon-dioxide</h2>

Explanation:

Wildfires are blazes that are impossible to control which burn land by huge amounts and burns over everything that comes in their paths like plant animals and other living creatures.

In the mentioned gases, Carbon dioxide is the main reason responsible for wildfire.

Carbon dioxide is known to be the main driver behind the warming of the earth 's atmosphere which is mainly induced by humans, and its increase in the concentration in the atmosphere is regularly increasing day-by-day.
