Answer:
B. by finding its speed and direction
Kinetic energy is the energy an object has due to its motion. As long as an object is moving at the same velocity, it will maintain the same kinetic energy. The kinetic energy of an object is calculated from the velocity and the mass of the object.

What is the major organic product obtained from the reaction of 2,2-dimethyl-1-propanol aqueous HBr at reflux
Answer:
See explanation
Explanation:
The mechanism involves SN1 nucleophilic substitution reaction. The -OH group of the alcohol is first protonated. Since water is a good leaving group, -OH2 leaves the substrate creating a primary carbo cation.
A 1,2 methyl shift now occurs to create a tertiary carbo cation which is more stable leading to the major product shown in the image attached to this answer.
Molten zinc chloride can be electrolysed.
Describe how this experiment can be carried out in a laboratory, explaining how the products of this electrolysis are formed.
(6) marks
Answer: The products of electrolysis are Zn(l) and [tex]Cl_2[/tex] gas
Explanation:
Electrolysis of a subastance is breaking it into its constituents by the action of electrical current.
In the electrolysis of molten zinc chloride, zinc metal is produced at the cathode which is a negative electrode and chlorine gas produces as the anode which is a positive electrode.
[tex]ZnCl_2(l)\rightarrow Zn^{2+}+2Cl^-[/tex]
At anode : [tex]2Cl^-(l)\rightarrow 2e^-+Cl_2(g)[/tex]
At cathode : [tex]Zn^{2+}(l)+2e^-\rightarrow Zn(l)[/tex]
It refers to the number of waves produced in one second.
Answer/Explanation:
f is the number of waves produced by a source per second, it is measured in hertz (Hz). T is the time it takes for one complete oscillation, it is measured in seconds. All waves, including sound waves and electromagnetic waves, follow this equation. A radio wave has a time period of 0.0000003333333 seconds.
Rank the following compounds in order of increasing stability, putting the least stable first. Group of answer choices II < I < III I < II < III III < II < I III < I < II
Hello. You forgot and show the compounds. The compounds are in the attached image.
Answer:
I < II < III
Explanation:
The stability of the presented compounds must be analyzed, taking into account the free electrons to form arrangements between the atoms. In this case, the molecules of greater stability follow the concept of valence and are characterized as those that manage to reach a large number of elements that manage to obey the octet rule.

Which statement is WRONG about electromagnetic waves?
A. Electric field is perpendicular to magnetic field.
B. Vibration of electric fields is perpendicular to propagation direction.
C. Different visible waves show different colors.
D. Different waves propagate in different speed.
Answer:
Different visible waves show different colors
In the electromagnetic spectrum, different visible waves show different colors.
What is electromagnetic spectrum?The electromagnetic radiation consists of waves made up of electromagnetic field which are capable of propogating through space and carry the radiant electromagnetic energy.
The radiation are composed of electromagnetic waves which are synchronized oscillations of electric and magnetic fields . They are created due to change which is periodic in electric as well as magnetic fields.
In vacuum ,all the electromagnetic waves travel at the same speed that is with the speed of air.The position of an electromagnetic wave in an electromagnetic spectrum is characterized by it's frequency or wavelength.They are emitted by electrically charged particles which undergo acceleration and subsequently interact with other charged particles.

Answer these questions. What are metals? Write the position of alkali metals and alkaline earth metals in the modern periodic table.
Explanation:
a metal is an element that readily forms positive ions (cations) and has metallic bonds.
Group two of the periodic table comprises the elements beryllium, magnesium, calcium, strontium, barium and radium. The elements in this group, which are all shiny and silvery-white in appearance, are known as the alkaline earth metals. Like the alkali metals, they form alkaline solutions when they react with water.

What volume of 0.130 M HCl is required for the complete neutralization of 1.30 g of NaHCO3 (sodium bicarbonate)?
Answer: Volume required is 0.115 L or 115 ml
Explanation:
moles of [tex]NaHCO_3[/tex] = [tex]\frac{\text {given mass}}{\text {Molar mass}}=\frac{1.30g}{84g/mol}=0.015mol[/tex]
The balanced chemical equation is:
[tex]HCl+NaHCO_3\rightarrow NaCl+H_2CO_3[/tex]
1 mole of [tex]NaHCO_3[/tex] requires = 1 mole of HCl
Thus 0.015 mol of [tex]NaHCO_3[/tex] requires = [tex]\frac{1}{1}\times 0.015=0.015[/tex] mole of HCl
Molarity of a solution is defined as the number of moles of solute dissolved per liter of the solution.
[tex]Molarity=\frac{n}{V_s}[/tex]
where,
n = moles of solute
[tex]V_s[/tex] = volume of solution in L
[tex]0.130=\frac{0..015}{V_s}[/tex]
[tex]V_s=0.115L[/tex]
Thus volume required is 0.115 l or 115 ml
Imagine blowing up a latex balloon. Assume that you tie the balloon to prevent air from escaping and then squeeze the balloon with one hand, so there is less space inside it. Then assume you use both hands (and maybe a friend’s hands) to squeeze the balloon so there is even less space inside. What do you think will happen to the balloon if you keep squeezing it to a smaller and smaller volume? Explain your prediction.
Answer:
Balloon will burst
Explanation:
The amount of volume that can be held by the latex will reduce yet the volume of air inside does not change. therefore the air inside will force the latex to break.
Assume that you tie the balloon to prevent air from escaping and then squeeze the balloon with one hand, so there is less space inside it then balloon will burst.
What is latex balloon?
latex is what latex balloons are made of. Due to tiny microscopic holes in the latex, it is porous and does not hold helium for as long as foil balloons (mylar balloons).
While latex balloons usually float for only 8–24 hours, foil balloons typically float for 4–21 days. But you can actually get a latex balloon to float longer than a foil balloon by using a product called hi-float, which extends the life of a latex balloon by 25 times the average float time.
In addition to being available in a variety of colors and prints in sizes ranging from 5" to 3 feet, latex balloons can also be printed in many colors, however if you want a detailed design you really need to use foil balloons.
Therefore, Assume that you tie the balloon to prevent air from escaping and then squeeze the balloon with one hand, so there is less space inside it then balloon will burst.

The focus of an earthquake is where it starts in the earth. The epicenter is the part directly above the focus on the surface. The fault is the part where the earth's crust splits.
4. What is the maximum no. of electrons that can be associated with the following set of
quantum numbers?
n=4, l=1, m=-1
a) 10
b) 6
d) 2
c) 4
Answer:
d) 2
Explanation:
We are given;
n = 4, l = 1, m = -1
We can tell that is is an orbital with sub shell as 3P.
Now, from Paul's exclusion principle, each orbital will have maximum of 2 electrons of each π with a spin of +½ and -½.
Since the maximum is seen to be 2, then option D is correct.
