state two advantages of parallel over series connection in table form?
Advantages of parallel combination over series combination are:
1) In parallel combination each appliance gets the full voltage.
2) If one appliance is switched on/of others are not affected.
3) The parallel circuit divide the current through the appliances. Each appliance gets proper current depending on its resistance.
4) In a parallel combination it is very easy to connect or disconnect a new appliance without affecting the working of other appliances.
choose what you like!
Note that there are also some disadvantages to using parallel connections over series connections, such as increased complexity in wiring and the need for additional safety measures when working with high voltage circuits. The choice between series and parallel connections depends on the specific requirements of the circuit and the devices being used.

Which compound contains nitrogen with an oxidation number of +3?
Answer:
Nitrous Acid [tex]N_{2}O_{3}[/tex]
Nitrogen is in the +3 oxidation state in N2O3. Nitrous acid is a weak acid.
The compound contains nitrogen with an oxidation number of +3 is N₂O₃ and nitrous acid HNO₂. Nitrous acid is a weak acid.
What do you mean by oxidation state ?The term oxidation state is defined as the total number of electrons that an atom either gains or loses in order to produce a chemical bond with another atom. The oxidation state is also called as oxidation number.
The formula for calculating oxidation states would be : The Highest Oxidation State for a Transition metal = Number of Unpaired electrons + Two s-orbital electrons.
The compound contains nitrogen with an oxidation number of +3 is N₂O₃ because it can acquire three electrons to form a chemical bond and to complete its outermost orbit (octet).
Thus, The compound contains nitrogen with an oxidation number of +3 is N₂O₃ and nitrous acid HNO₂.

If you worked at a job for 9.00/hour, what type of correlation is the number of hours worked and your take-home pay?
Answer:
There is a linear correlation between the number of hours worked and take-home pay. And more exactly, a direct proportionality. [tex]C = 9\cdot t[/tex]
Explanation:
From statement we deduce that amount of hours worked ([tex]t[/tex]) (Independent variable, measured in hours) is directly proportional to take-home pay ([tex]C[/tex]) (dependent, measured in monetary units), since proportionality ratio is constant and, therefore, there exists a linear correlation between both variables. That is:
[tex]C \propto t[/tex]
[tex]C = k\cdot t[/tex] (Eq. 1)
Where [tex]k[/tex] is the proportionality ratio, measured in monetary units per hour. If we know that [tex]k = 9\,\frac{m.u.}{h}[/tex], then the resulting correlation is:
[tex]C = 9\cdot t[/tex]
There is a linear correlation between the number of hours worked and take-home pay.

You will analyze four substances in this lab. Based on their chemical formulas and what you already know about covalent and ionic compounds, make a prediction for each compound.Cornstarch, a carbohydrate consisting of hydrogen, carbon, and oxygen
Answer:
Oil: covalent
Cornstarch: Covalent
Sodium chloride: Ionic
Sodium bicarbonate: Ionic
Explanation:
Covalent compounds are formed by sharing of electrons between non metals whereas ionic compounds are formed by transfer of electrons from metals to non metals.
1. Oil, which is built from the nonmetals hydrogen, carbon, and oxygen: forms a covalent compound by sharing of electrons between non metals hydrogen, carbon, and oxygen. Covalent compounds are insoluble in water.
2. Cornstarch, a carbohydrate consisting of hydrogen, carbon, and oxygen: forms a covalent compound by sharing of electrons between non metals hydrogen, carbon, and oxygen. Covalent compounds are insoluble in water.
3. Sodium chloride (table salt), whose formula is NaCl is formed by transfer of electrons from sodium to chlorine.Ionic compounds are soluble in water.
4. Sodium bicarbonate, whose formula is is formed by transfer of electrons from sodium to .Ionic compounds are soluble in water.

. The solution is lighter in color,
The volume of solution is the same.
• The metal strip is shiny above the surface of the solution
• The metal strip is not shiny below the surface of the solution.
• The metal strip below the surface of the solution has a dark
coat of flaky material
• When the metal strip is touched, the flaky material falls off.
Based on their observations, can the students correctly conclude that a chemical reaction occurred?
A. No, because the metal strip was still visible
B. Yes, because a new material of a different color formed on part of the metal strip
c. No, because the solution stayed blue

Yes, because a new material of a different color formed on part of the metal strip.
What is a Chemical reaction?When atoms establish or break chemical bonds, chemical processes take place. Reactants are substances that begin a chemical reaction, while products are the compounds that are created as a result of the reaction. Until the reactants are exhausted, some chemical reactions merely proceed in one direction. It is claimed that these responses are irreversible. Some responses are categorized as reversible. Reactions that are reversible can occur both forward and backward. Reactants change into products in a reversible reaction, but products can also change back into reactants. In actuality, both the forward response and its reverse will occur simultaneously. This oscillation lasts until a particular relative balance between reactants and products is attained a condition known as equilibrium. The forward and backward processes continue to occur at equilibrium, but there is no longer any change in the relative concentrations of products and reactants.

You are out on a hike, and you notice that the line of telephone wires you have been following along a slope is crooked. Two of the posts are much farther down slope then the others. What has likely occurred on this hillside?
Answer:
The awnser is creep
Explanation:
There don't appear to be any dial tone problems on the telephone caused by broken wires, connectors, wall jacks, or other network-interfering hardware.
What is hardware ?Hardware describes the physical parts of the computer or its delivery mechanisms for the software's written instructions to be stored and executed. The device's intangible component that enables user interaction with the hardware is called the software.
Software is referred to as "soft" because it is flexible, but hardware is referred to as "hard" because it is rigid in terms of modifications. Software often instructs hardware to carry out any command.
Since a smartphone is fundamentally a small computer, it has several parts in common with computers, such as processors and memory. It's critical to balance your demands on this hardware because these components are continuously improved in new phone generations.
Thus, It doesn't seem that any broken wires, connectors, wall jacks, or other network-interfering gear are the root of any dial tone issues on the hardware.

Calculate the density of an object using the following information: Mass = 50 grams and the initial water level is 30-ml in a graduated
cylinder, but rose to 40-ml after the object was dropped into it.
The density of an object = 5 g/ml
Further explanationDensity is a quantity derived from the mass and volume
Density is the ratio of mass per unit volume
The unit of density can be expressed in g/cm³ or kg/m³
Density formula:
[tex]\large {\boxed {\bold {\rho ~ = ~ \frac {m} {V}}}}[/tex]
ρ = density
m = mass
v = volume
Mass = 50 g
Volume of the object =
[tex]\tt 40-30=10~ml[/tex]
So the density :
[tex]\tt \rho=\dfrac{50}{10}\\\\\rho=\boxed{\bold{5~g/ml}}[/tex]
