Answer:
1- The components in a series circuit are arranged in a single path from one end of supply to another end. However, the multiple components in a parallel circuit are arranged in multiple paths where the two end terminals of the battery.
2- In the series circuit, different voltage exists across each component in the circuit. Whereas in the parallel circuit, the same voltage exists across the multiple components in the circuit.
3- The equivalent resistance in case of a series circuit is always more than the highest value of resistance in the series connection. While the equivalent resistance in the parallel circuit is always less than any of the individual resistances in parallel combination.
4- A fault in one of the components of the series circuit causes hindrance in the operation of a complete circuit. As against fault in a single component in a parallel network do not hinder the functioning of another part of the circuit.
The detection of a fault in case of a series circuit is difficult, but it is quite easy in parallel circuits.
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]

What is true about warm, saturated air?
It contains less water vapor than cold air.
It contains the same amount of water vapor as cold air.
It does not contain any water vapor.
It contains more water vapor than cold air.
Answer:
It contains more water vapor than cold air
According to the process of conduction which take place from hot to cold end warm saturated air has more water vapor than cold air.
Conduction is defined as a process as a means of which heat is transferred from the hotter end of the body to it's cooler end.Heat flows spontaneously from a body which is hot to a body which is cold.
In the process of conduction,heat flow is within the body and through itself.In solids the conduction of heat is due to the vibrations and collisions of molecules while in liquids and gases it is due to the random motion of the molecules .
As per the concept of conduction, warm hair has more water vapor than cold air, thus the correct option is that warm, saturated air has more water vapor than cold air.

Which elements form covalent bonds? Which other element is included in the group?
Complete a write up about the elements in Ammonia and explain how the elements bounded to create the new substance.
Answer:
Explanation:
Ammonia consist of nitrogen and hydrogen.
Chemical equation:
N₂ + H₂ → NH₃
Balance chemical equation:
N₂ + 3H₂ → 2NH₃
We can see that nitrogen and hydrogen react with each other and from ammonia.
Nitrogen is present in group 5A. The atomic number of nitrogen is 7. Its atomic mass is 14 amu. It has 5 valence electron.
Electronic configuration:
N₇ = 1s² 2s² 2p³
we can see there are five electron in outer most shell. Thus, nitrogen needs three more electrons to complete the octet. When it combine with other atoms it gain three electron from them
While hydrogen is present in group 1A. It has one valence electron. In ammonia (NH₃) when nitrogen react with hydrogen it gain three electrons thus three atoms of hydrogen combine with one atom of ammonia because one hydrogen atom can share only one electron. Covalent bond is formed between nitrogen and hydrogen and new substance formed is called ammonia.
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.

please help timed !! due rn !! What happens to particle motion as two substances come to thermal equilibrium?
Answer:
When two substances that are of different temperatures are brought together and there is heat transfer such that the substances come to thermal equilibrium, the effect on the particle motion are as follows
1) The particle motion of the hotter body reduces, because its temperature reduces
2) The particle motion of the colder body increases, because its temperature increases
3) For gases, the volume and or pressure reduces for the hotter body, and if the temperature of the gas falls below the boiling point temperature, the gas will change into liquid
For the colder gas, only the volume and or pressure increases and the temperature rises
4) For liquids, if the temperature of the hotter liquid falls below the melting point, the hotter liquid will become a frozen solid
For the the colder liquid, if the temperature is raised above the boiling point, the liquid changes into gas and the temperature does not rise above the boiling point temperature, until all the cold liquid has evaporated
5) For solids, the vibration of the particles of the hotter substance reduces and the solid becomes more brittle
For the colder body, the rise in temperature causes an increase in vibration of the particles, and if the temperature rises above the melting point, the colder solid will begin to melt

Answer:
3. One example of condensation is dew forming on grass or leaves early in the morning when the air is cooled/cooling.
4. This is called freezing. For example, when water turns into ice (a solid) because it freezes.
5. This is called melting. The butter reached its melting point and turned into a liquid.
6. Adding or removing energy causes changes in states of matter. Temperature for example can cause melting and freezing.
7. Water which collects as droplets on a cold surface when humid air is in contact with it.
8. Evaporation/vaporization
9. before- particles are compact
during- particles vibrate
after- the particles move freely
10. condensation because it is going from gas into a liquid
11. Evaporation, I know because when liquid gets heated after a period of time and it reaches its boiling point, it will begin evaporating.
12. When a solid is heated the particles gain energy and start to vibrate faster and faster. ... Although the particles are still loosely connected they are able to move around. At this point the solid is melting to form a liquid. The particles in the liquid are the same as in the solid but they have more energy.
13. Sublimation is the process of transformation directly from the solid phase to the gaseous phase, without passing through an intermediate liquid phase.
14. freezing because particles are becoming compact and getting slower because of decrease in temperature
15. Examples are mothballs, dry ice, snow in the winter months, freeze-drying (ice crystals in a frozen food bag), air fresheners, and printers that print out high-resolution images.
16. Try and think of it in terms of the molecules. The temperature is such that the molecules are all bound together into a solid. Occasionally a surface molecule picks up enough energy to break it bond,.. a statistical probability ,and drifts away. The overall temperature of the solid is reduced by that event,as temperature is just an average of the energy. A little more heat flows into the material ,from the ambient environment, and another molecule escapes, and so the process continues….. if the concentration of the molecules in the vapour space above the solid, is low the reverse process of molecules condensing onto the surface,and releasing energy back into the solid is low.
