An object is placed at 0 on a number line. It moves 3 units to the right, then 4 units to the left, and then 6 units to the right. What is the displacement of the object?
Answer:
5
Explanation:
Distance is how far something goes and Displacement is how far it is from 0 or from the starting point. Additionally, displacement is a vector so it has a direction, in this case, left or right. To make this shorter let's just find displacement. So you're at 0 and you go 3 units to the right and so you're at positive 3 on the line. Next, you move 4 units to the left so now you're at -1. Finally, you move 6 units to the right and now you're at postive 5. Now you're +5 units away from 0 and so +5 is your displacement (5 units to the right is also correct)
Answer: +5 units or 5 units to the right (as long as it has a sign or a direction it's correct)

Los gatos tienen muchas opciones para comer como ratones, peces, cucarachas, etc. Por ejemplo: Planta -> Ave -> Gato -> ??? ¡¿Quién mata al gato para comérselo?! POR FAVOR ESPARA UN PROYECTO DEL ORIGEN DEL GATO
Answer:
Pumas, lobos y coyotes, águilas, serpientes, halcones, búhos y perros.
Explicación:
Pumas, lobos y coyotes, águilas, serpientes, halcones, búhos y perros son los animales que matan al gato y se alimentan de ellos. Estos organismos son los depredadores de los gatos y dependen del gato y de algunas otras especies para cumplir con su requerimiento de alimento. Algunos animales matan directamente al gato a través de sus dientes fuertes, mientras que otros matan al gato a través del veneno que está presente en su boca.

true canine teeth, and a split upper lip. The family Camelidae originated in North America. The physical features of animals in this family and the family's
goopraphical origin provide evidence that all these animals -
have slowly evolved to become herbivores
live in the same type of ecosystem
have a common ancestor

Sodium metal reacts whit hydrochloric acid to produce salt and hydrogen gas. What are the reactants in this chemical reaction
Answer:
Na (sodium) and HCl (hydrochloric acid)
Explanation:
The products are the salt and hydrogen gas
Whenever you see the word react it means those are the reactants (usually whatever compound comes before and after the word). Because they are reacting with each other.
Whenever they say "is produced" those are the products
If something is 12 grams and has a volume of 1.6 cubic centimeters, how many grams per cubic centimeter.
Answer: 7.5 grams per cubic centimeter.
Explanation:
We area given that , Mass of something is 12 grams
Volume of that thing is 1.6 cubic centimeters
To find gram per cubic centimeters, we will divide Mass by Volume ( which computes Density)
Number of gram per cubic centimeters = [tex]\dfrac{12}{1.6}[/tex]
Number of gram per cubic centimeters = 7.5
Therefore, 7.5 grams per cubic centimeter. (density of the thing)

In a large population of sea stars, half of the individuals possess the red allele and half possess the purple allele. A change in the genome has been introduced, and many of those with purple allele are dying. Therefore, the red allele has become more frequent over time.
Which of the following requirements for the Hardy-Weinberg equilibrium is not being met?
Answer:
A
Explanation:
All mating must be totally random
Hardy-Weinberg equilibrium is a mathematical model that describes the genetic equilibrium of a population in terms of allele frequencies. It states that allele frequencies in a population remain constant over time in the absence of any evolutionary forces.
What are the requirements of the law ?In order for this balance to be maintained, five basic requirements must be met: large population size, random mating, no mutations, no migration, and no natural selection. In this case, the starfish population does not satisfy the fifth requirement for no natural selection.
Natural selection occurs as individuals with the purple allele die off, resulting in the red allele becoming more common over time. This type of directional selection causes allele frequencies to deviate from Hardy-Weinberg equilibrium.
Therefore, no natural selection requirement is met in this starfish population. This causes allele frequencies to change over time, leading to a deviation from Hardy-Weinberg equilibrium.

1) What is the control group? 2) What is the experimental group? 3) What is the independent (manipulated) variable? 4) What is the dependent (responding) variable? 5) What should Tina's conclusion be?
Complete question:
Tina asks the question “Does caffeine increase the heart rate of an earthworm?” In Test 1, she measures the heart rate by looking at the earthworm under a microscopes, the earthworm has a heart rate of 50 bpm (beats per minute). In Test 2, she places a few drops of caffeine on the earthworm’s skin and measures the rate again. In this test, the heart rate is 68 bpm.
1) What is the control group?
2) What is the experimental group?
3) What is the independent (manipulated) variable?
4) What is the dependent (responding) variable?
5) What should Tina's conclusion be?
Answer:
Individuals from test 1Individuals from test 2CaffeineHeart rateTina´s hypothesis is correct. Caffeine increases the heart rate of an earthworm.Explanation:
During an experiment, data from an experimental group is compared with the data from a control group. Both groups are selected from the same pool or population, so they are identical in all aspects except for the independent variables.
The control group is used to identify any other factors influencing the results obtained in the study, apart from the modified variables of the treatment.
The experimental group is the one affected by the experimental procedure or treatment. The researcher voluntarily changes the independent variables in the experimental group to observe how they affect the group under study. These variables are kept constant in the control group, not influencing the results, while the experimental group receives the treatment. There can be several experimental groups.
Independent (manipulated) variable: Refers to all the variables in an experiment that provoke a response in another variable. An independent variable is the one that changes or is controlled and modified in the experiment to analyze how another variable responds to it. It changes to analyze its effects on the dependent variable. Usually, the independent variable is represented by the X letter. Dependent variable: Refers to the variable, which response depends on any change in the independent variable. It represents a quantity of something which value depends on how the independent variable is modified. The change in the dependent variable might be proportional or inversely proportional to the change in the manipulated variable. It is usually represented using the letter Y. Controlled variable: Refers to the variables that have no influence on the results. These variables do not affect the change in the dependent variable values.1) What is the control group?
Individuals from test 1 compose the control group. They are not affected by the treatment. Tina just uses them to measure the normal heart rate and to compare them with individuals from test 2.
2) What is the experimental group?
Individuals from Test 2 compose the experimental group. They are affected by the treatment. Tina drops caffeine on their skin to see how it affects the worms.
3) What is the independent (manipulated) variable?
Caffeine is the independent variable. Tina manipulates the number of drops she places on the worm´s skins.
4) What is the dependent (responding) variable?
Heart rate is the dependent variable. Tina evaluates how the heart rate changes in individuals with or without caffeine.
5) What should Tina's conclusion be?
Caffeine increases the heart rate of an earthworm. It changes from 50 to 68 bpm. Tina´s hypothesis is correct.
Which product forms from the reaction between nitrogen (N)
(CI)?
A. NCI
B. NCI
C. N2CI
O D. N2C1
Answer:
None of the above
Explanation:
Because as N has the valence of 3 when it reacts with Cl of 1 as valence they will form NCl3Answer:
The product of the reaction between nitrogen (N) and (CL) is nitrogen trichloride (NCl3)
Explanation:
Although by seeing the question's answer choices, I think it was an error to detect the question (image) by Brainly as 2 of the answers is written the same.
However, when nitrogen gas reacts with chlorine gas, the product is gaseous nitrogen trichloride (NCL3), I guess 1 of your answer must be NCL3.
