The momentum of the bowling ball will be greater than the rest balls.
The correct answer to the question is Option C. The 5 kg bowling ball
Momentum is defined as the product of mass and velocity i.e
Momentum = mass × velocity
If we keep the velocity of the object constant, the momentum will depend on the mass of the object.
Thus, the higher the mass, the greater the momentum and the lesser the mass, the smaller the momentum.
From the question given above,
Mass of tennis = 0.5 Kg
Mass of basketball = 2 Kg
Mass of bowling ball = 5 kg
We can see that the bowling ball has a higher mass.
Therefore, the momentum of the bowling ball will be greater than the rest balls.
The correct answer to the question is Option C. The 5 kg bowling ball

Shanika is an engineer at an amusement park who is experimenting with changes to the setup for a magnetic roller coaster ride. In one ride, there are two identical roller coaster cars (orange and green) that start on opposite sides of a large magnet located at the center of a station. Shanika wants to get the largest increase in potential energy she can by moving one car one space to the left or the right. Shanika can move the orange car to point A or point B, or she can move the green car to point C or point D. Which movement should she make? Why will that movement result in the largest increase in potential energy? Describe the magnetic force that will act on the roller coaster car she moves. What should I do for the Green cart?
The orientation of the poles of the magnet on the cars and the large
magnet are like poles.
The correct responses are;
First question
Move the orange car from A to B Move the green car from D to CSecond question:
The reason is reducing the distance increases the magnetic field strengthThird question:
It pushes the cars away in the opposite direction.
Fourth question:
Place the green car at point C to get the largest potential energyReasons:
Potential energy is the energy an object has due to its location.
Energy is a product of force and distance, and therefore, if the force,
experienced by the object increase, the potential energy of the object
increases.
The strength of a magnetic field, B, is given by the formula;
[tex]\displaystyle B = \frac{\mu_0 \cdot I}{2 \cdot \pi \cdot d}[/tex]
Where;
B = The magnetic field strength
I = Current
d = The distance from the source of the magnet
μ₀ = The permeability of free space = 4·π × 10⁻⁷ T m/A
Therefore, the strength of the magnet is higher closer to the source.
First question
In a magnet, like poles push each other back, and given that the poles of the magnet adjacent to each other are like poles, to get the largest increase in she should move the cars towards the large magnet.
Move the orange car from A to B Move the green car from D to CSecond question:
The reason why the movement will result in the largest increase in potential energy is because like polls repel each other and the strength of a magnetic field increases closer to the magnet
Third question:
The magnetic force that will act on the roller coaster car moved towards the large magnet, pushes the car in the opposite direction.
Fourth question:
The green cart should be moved from point D to point C to get the largest potential energy

what is atomic mass in Chemistry
Answer:
the average mass of the atoms of an element measured in atomic mass unit (amu, also known as daltons, D)
Explanation:
is isopropyl alcohol the same as hydrogen peroxide
Answer:
Unlike isopropanol, hydrogen peroxide is not a type of alcohol. You might recognize its chemical formula, H2O2, as being similar to that of water (H2O). The difference is that hydrogen peroxide has two oxygen atoms instead of one. That one extra oxygen atom makes it a strong oxidizer.

Analysis of a molecule of DNA showed that cytosine accounted for 42 per cent of the
content of the nitrogenous bases. Calculate the percentage of bases in the molecule
which would be thymine. Show your working.
8%
Explanation:
In a DNA molecule the no. of Adenine bases equal to that of Thymine bases
The no. of Cytosine bases equal to that of Guamine bases.
If we take no. of Thymine bases as x and no. of Cytosine bases as y,
Adenine + Thymine + Cytosine + Guamine = 100
x + x + y+y = 100
2( x+y) = 100
x+y = 50
y=42
therefore x= 50-42 = 8%

Use your periodic table, notes on transition metals, and polyatomic ion table to correctly answer the following:
What is the ionic compound formed from calcium and sulfide ions?
Select one:
O a.
Cas
O b. Ca s
O c. CaSO4
O d. CazS2
Answer:
The high melting point is also consistent with its description as an ionic solid. In the crystal, each S2− ion is surrounded by an octahedron of six Ca2+ ions, and complementarity, each Ca2+ ion surrounded by six S2− ions.
Explanation:
You can use the periodic table to predict whether an atom will form an anion or a cation, and you can often predict the charge of the resulting ion. Atoms of many main-group metals lose enough electrons to leave them with the same number of electrons as an atom of the preceding noble gas. To illustrate, an atom of an alkali metal (group 1) loses one electron and forms a cation with a 1+ charge; an alkaline earth metal (group 2) loses two electrons and forms a cation with a 2+ charge, and so on. For example, a neutral calcium atom, with 20 protons and 20 electrons, readily loses two electrons. This results in a cation with 20 protons, 18 electrons, and a 2+ charge. It has the same number of electrons as atoms of the preceding noble gas, argon, and is symbolized Ca2+. The name of a metal ion is the same as the name of the metal atom from which it forms, so Ca2+ is called a calcium ion.
When atoms of nonmetal elements form ions, they generally gain enough electrons to give them the same number of electrons as an atom of the next noble gas in the periodic table. Atoms of group 17 gain one electron and form anions with a 1− charge; atoms of group 16 gain two electrons and form ions with a 2− charge, and so on. For example, the neutral bromine atom, with 35 protons and 35 electrons, can gain one electron to provide it with 36 electrons. This results in an anion with 35 protons, 36 electrons, and a 1− charge. It has the same number of electrons as atoms of the next noble gas, krypton, and is symbolized Br−. (A discussion of the theory supporting the favored status of noble gas electron numbers reflected in these predictive rules for ion formation is provided in a later chapter of this text.)

the proton concentrations of three solutions at 25 °c are given. classify the solutions as acidic, basic, or neutral.
This problem is giving information about the proton concentrations of three solutions at 25 °C. Despite they are not numerically given, we can propose three scenarios to see how to approach the question.
Let the following solutions to come up:
[H⁺] = 2.63x10⁻³ M
[H⁺] = 1.00x10⁻⁷ M
[H⁺] = 4.511x10⁻⁹ M
The first step, will be the calculation of the pH for each solution via:
pH = -log([H⁺])
So that they turn out to be:
pH = -log(2.63x10⁻³ M) = 2.580
pH = -log(1.00x10⁻⁷ M) = 7.000
pH = -log(4.511x10⁻⁹ M) = 8.3457
In such a way, since acidic solutions have a pH below 7, neutral have a pH equal to 7 and basic have it above 7, we infer the first one is acidic, second one is neutral and third one is basic.
Thus, you can reproduce this methodology with the proton concentrations you are given.

According to the concept of solubility, boiling water and then adding sugar to it will take longer time to dissolve than adding water and sugar together to boil as thermal energy requires to dissolve sugar will be less.
What is solubility?Solubility is defined as the ability of a substance which is basically solute to form a solution with another substance. There is an extent to which a substance is soluble in a particular solvent. This is generally measured as the concentration of a solute present in a saturated solution.
The solubility mainly depends on the composition of solute and solvent ,its pH and presence of other dissolved substance. It is also dependent on temperature and pressure which is maintained.Concept of solubility is not valid for chemical reactions which are irreversible. The dependency of solubility on various factors is due to interactions between the particles, molecule or ions.

¿Qué relación existe entre la teoría del octeto de Lewis con los enlaces iónicos y
covalentes?
Por definición de enlace iónico, covalente y regla del octeto, la relación existente entre la teoría del octeto de Lewis con los enlaces iónicos y covalentes es que dichos enlaces se producen con el objetivo de completar la última capa de electrones y adquirir estabilidad.
Enlace iónicoPor un lado, se produce un enlace iónico entre átomos metálicos y no metálicos, donde los electrones se transfieren completamente de un átomo a otro. Durante este proceso, un átomo pierde electrones y otro los gana, formando iones. Por lo general, el metal cede sus electrones formando un catión al elemento no metálico, que forma un anión.
Enlace covalentePor otro lado, el enlace covalente es el enlace químico entre átomos donde los electrones se comparten, formando una molécula. Se establecen enlaces covalentes entre elementos no metálicos. El par de electrones compartidos es común a los dos átomos y los mantiene unidos.
Regla del octetoEn ambos casos se cumple con la regla del octeto, que establece que los átomos de los elementos se enlazan unos a otros en el intento de completar su capa de valencia con ocho electrones. Es decir que los átomos van a tender a ceder o compartir electrones para completar ocho electrones en la capa de valencia mediante un enlace iónico, covalente o metálico.
En otras palabras, el objetivo es tener la configuración electrónica del gas noble más cercano, teniendo así la última capa de electrones completa y adquiriendo estabilidad.
En resumenEn resumen, la relación existente entre la teoría del octeto de Lewis con los enlaces iónicos y covalentes es que dichos enlaces se producen con el objetivo de completar la última capa de electrones y adquirir estabilidad.
