So this is asking how they can stop the carp from spreading. A. is talking about the asian carps jumping out of water damage boats but this has nothing to do with what we can do to stop them from spreading!! B. Is saying how when you release the carp into a body of water can cause them to spread even more! so that isnt what we need. C. Is about how plants provide safe places for carps to have more carps and that's what we are trying to stop D. This is saying that we can throw bait we dont want in the trash not the water so when somebody catches an asian carp people know and can not release any more fish to the body of water .
D. - Makes the most sense because it talks about what people can do to stop the spread of the invasive species The Asian Carps
Sam ran a 2000-meter race. He started at 9:00 AM and finished at 9:15 AM. He started out fast but slowed down toward the end. Calculate Sam's average speed during the race.
Answer:
Sam's average speed = 2.22 m/s
Explanation:
The average speed refers to the speed with which a distance is covered within a particular time duration. The average speed of a moving object can be obtained by summing up all the varying speeds as the object moves from one point to another, within a particular time frame.
Sams average speed can be calculated using this formula:
Average speed = distance / time
Distance covered = 2000 meters
Time taken to cover the distance = 9:15 am - 9:00 am = 15 minutes = 15 X 60 seconds = 900 seconds
Sam's average speed = 2000meters / 900 secs = 2.22 m/second

describe how the particles in the pot transfer energy
Answer: When they do, they transfer some of their energy. The energy is transferred from particle to particle. It is sort of like a row of dominoes falling over. In this process, thermal energy moves through a substance. It can even move into other nearby substances. In Figure above, conduction occurs between particles of the metal in the pot. It also occurs between particles of the pot

leading zeros to the left of a decimal point
all of the above
none of the above
Answer:
leading zeroes to the left of a decimal point. and trailing zeros to the left of an invisible decimal point.
Explanation:
All nonzero digits are significant figures. Example: 713 has three significant figures. 18,991 has five significant figures.Zeros located between two nonzero digits are significant figures. Example: 505 has three significant figures. 17,009 has five significant figures.Zeros at the ends of numbers are only significant if there is a decimal point in the number. Example: 502.00 has five significant figures (5,0,2,0,0). 5020 has three significant figures (5,0,2) 100,000 has one significant figure (1)Zeros that come before the first nonzero digit are not significant. Example: 0.0007 has one significant figure (7). 0.0970 has three significant figures (9,7,0)The picture above is a diagram of what earth-sun-moon phenomena?

What size volumetric flask would you use to create a 1.25 M solution using 29.75 g of MgCl2?
Answer:
250 ml
Explanation: I got it right on the lab.
The size of the volumetric flask that would you use to create a 1.25 M solution using 29.75 g of MgCl₂ is 250mL.
How do we calculate volume of the solution?
Volume (V) in liter of the solution will be calculated by using the molarity (M) formula as:
M = n/V, where
n is the moles of the solute and it will be calculated by using mass as:
n = W/M, where
W = given mass
M = molar mass
Moles of 29.75g of MgCl₂ = 29.75g / 95g/mol = 0.313 mol
Given that molarity of solution = 1.25M
On putting values on the equation of molarity we will get the value of volume as:
V = 0.313 / 1.25 = 0.2504 L = 250mL
For the preparation of 250 mL of MgCl₂ solution we required the volumetric flask of 250 mL.
Hence volumetric flask of 250mL is required.

A skateboarder traveling at 7.0 meters per second rolls to a stop at the top of a ramp in 3.0 seconds. What is the skateboarder's acceleration? acceleration=[acceleration]m/s2
Answer:
The skateboarder's acceleration is -2.33 m/s².
Explanation:
The acceleration of an object is a magnitude that indicates how the speed of the object changes in a unit of time. That is, acceleration is the change in speed in a unit of time.
Acceleration is calculated as the relationship between the variation or change in the speed of a mobile and the time used for said change:
[tex]acceleration=\frac{change in the speed}{time}=\frac{final speed - initial speed}{time}[/tex]
In this case:
final speed= 0 m/sinitial speed= 7 m/stime= 3 sReplacing:
[tex]acceleration=\frac{0 m/s - 7 m/s}{3 s}[/tex]
and solving you get:
acceleration= -2.33 m/s²
The skateboarder's acceleration is -2.33 m/s².

name the following compound Mol2
Answer:
you cant answer this
Explanation:
you left something out of the question
On the periodic table, what is a group? For the main groups, what characteristic
do the elements have in common?
In modern times, we know that the elements in a given group (also known as a family or column) have the same number of valence electrons, with ground state configurations having a consistent pattern, for instance:
F 1s2 2s2 2p5, Cl 1s2 2s2 2p6 3s2 3p5, Br 1s2 2s2 2p6 3s2 3p6 3d10 4s2 4p5, etc.
Of course, the ground state configurations play a major role in determining how an element reacts and what compounds it forms. Thus, the elements in a given group have similar properties.
The structure of the table also predicts how the properties vary. For instance, atomic radius increases down a group as does metallic character.
