How can the gravitational potential energy of an object be changed?

Answers

Answer 1

Answer:

Gravitational potential energy may be converted to other forms of energy, such as kinetic energy. If we release the mass, gravitational force will do an amount of work equal to mgh on it, thereby increasing its kinetic energy by that same amount (by the work-energy theorem).

Answer:

I don't know that question answer because I am in 7 class so mind it

Answer:

Positive Geotropism means growth of the plants towards the Gravitational force. e.g.It means When a plant's root grows towards Gravitational force . It is positive geotropism. Negative Geotropism means growth of the plant against the Gravitational force. e.g. When a plant's steam grows towards sunlight.

Fractional distillation is a method for separating a liquid from a mixture of two or more liquids. For example, liquid ethanol can be separated from a mixture of ethanol and water by fractional distillation. This method works because the liquids in the mixture have different boiling points.

What is the molarity of a hydrochloric acid solution, when 30.0 mL is neutralized by 48.0 mL of 0.100 mol/L
calcium hydroxide?

Answers

The molarity of a hydrochloric acid solution : 0.32 M

Further explanation  

Titration is a procedure for determining the concentration of a solution by reacting with another solution which is known to be concentrated (usually a standard solution).

Titrations can be distinguished including acid-base titration, depositional titration, and redox titration. An acid-base titration is the principle of neutralization of acids and bases is used.  

Acid-base titration formula  

Ma. Va. na = Mb. Vb. nb  

Ma, Mb = acid base concentration  

Va, Vb = acid base volume  

na, nb = acid base valence  

1 ⇒HCl (valence=1, HCl ⇒H⁺+Cl⁻, one H⁺)

2⇒Ca(OH)₂(valence=2, Ca(OH)₂⇒Ca²⁺+2OH⁻, two OH⁻)

M₂=0.1 M

V₂=48 ml=0.048 L

V₁=30 ml=0.03 L

2. An all natural mosquito repellent

is trying to make its way into the

market. One arm is sprayed with the

repellent and one arm is not sprayed

with anything. After 3 hours, the

number of mosquito bites is counted. What is the control group

Answers

Answer:

The arm that was not sprayed with anything

Explanation:

The control group would be the arm that was not sprayed with anything.

The control group during an experiment is a group that forms the baseline for comparison in other to determine the effects of a treatment. The control group does not include the variable that is being tested and as such, it provides the benchmark to measure the effects of the tested variable on the other group - the experimental group. In this case, the experimental group would be the arm that was sprayed with the repellent.

What is the mole ratio of PCl3 to PCl5?

Answers

Answer: The mole ratio of [tex]PCl_3[/tex] to [tex]PCl_5[/tex] is 1: 1

Explanation:

According to the balanced chemical equation ,the number of atoms of each element has to be same on reactant and product side. The stoichiometric coefficients of the species represent their number of moles.

[tex]PCl_3+Cl_2\rightarrow PCl_5[/tex]

Thus in the reactants, there is 1 mole of [tex]PCl_3[/tex] and 1 mole of [tex]Cl_2[/tex] molecule. And thus there is 1 mole of [tex]PCl_5[/tex] in the product as well.

Thus the mole ratio of [tex]PCl_3[/tex] to [tex]PCl_5[/tex] is 1: 1

What will oxygen likely do to complete its outermost shell, based on the Lewis dot diagram shown?

accept electrons
accept some electrons and give up other electrons
move electrons from the inner shell to the outer shell
give up electrons

Answers

Answer:

A. Accept electrons

Explanation:

The octet rule states that 8 electrons stabilizes a molecule. This means that oxygen will try to fill the two empty spots with electrons from other molecules. The Lewis Dot diagram shows these two empty spots with the empty circles at the bottom.

Lewis dot structures, also known as electron dot structures, are schematics that show the interatomic chemical bonds in a molecule. Additionally, they show how many lone pairs there are overall in each of the atoms that make up the molecule. Here 'O' accepts electrons. The correct option is A.

The electrical structures of the elements, especially the electron pairings, are reflected in the Lewis dot structures. Lewis structures can be viewed as "electron bookkeeping" and are a helpful approach to condensing some bonding-related information. Each dot in a Lewis dot structure corresponds to 1 electron.

Group 6 member oxygen still requires two additional electrons to complete its outer shell and remain stable. According to the octet rule, an object needs 8 valence electrons in the outer shell to be stable.

Thus the correct option is A.

In the article, Invasion of the Periodical Cicadas, why do scienctists believe that cicadas only reproduce every 13 or 17 years? Explain your answer with evidence from the text.

Answers

Hi, you've asked an incomplete question. However, I assumed you are referring to the article found on the Scientific American website.

Explanation:

Remember, according to that article we are told that scientists notice that these insects have a long nymphal (immature form before becoming adults) stage, one that can last up to 13 to 17 years on the ground before they leave the ground looking for mating partners.

Because it is only after mating occurs at this point that their eggs are laid, that is why scientists believe that cicadas only reproduce every 13 or 17 years.

According to the diagram which statement best describes what happens when two astronauts collide in space? Will give crown!!!!

Answers

Answer:

J. Their momentum is conserved

Explanation:

According to the diagram, the best statement that describes what happens when two astronauts collides in space is that their momentum is conserved.

The momentum before collision is 320kgkm/hr and after collision it is 320kgm/s

 This collision is an inelastic collision;

    momentum before  = momentum after

              m₁v₁ + m₂v₂     =       v(m₁ + m₂)

m₁ = 80kg

v₁  = 4km/hr

m₂ = 80kg

v₂  = 0

v  = 2km/hr

 Insert the parameters;

              (80 x 4) + (80 x 0)    = 2(80 + 80)

                    320                      = 320
