A 5 kg block
is pulled across a table by a horizontal force of 4O N with a frictional force ot 8N pOsing the motion. Calculate the acceleration of the oject. 12 An ahia iddt
Answer:
By Newton's 2nd law, m*a=sum_of_forces where m is the mass and a the acceleration. Here there are two forces in opposed directions.
Thus 5*a=40-8=32 therefore a=32/5=6.4m^s/2
3.6 x 10-6 in standard notation.
Answer: 0.000036
Explanation:The standard form is just the normal method of depicting a number. To get from scientific notation to standard form, you would multiply the number from the scientific notation by the increasing / decreasing factor (10n). When the factor decreases, the 10 is raised to a negative power and the decimal moves to the left n amount of times (example the
10−5 moves your decimal in 3.6 over to the left 5 times leaving you with 0.000036). The opposite is true for increasing factors.
3.6 x 10⁻⁶ in standard notation is 0.0000036.
Standard notation refers to the conventional symbols, terms, and formats used to represent mathematical, musical, scientific, or other technical concepts.
Scientific notation is a way to express very large or very small numbers using powers of 10. It is commonly used in scientific and mathematical calculations to represent numbers that are too big or too small to be conveniently written in standard decimal notation.
To convert a number in scientific notation to standard notation, multiply the coefficient by the power of 10.
In 3.6 x 10⁻⁶, the coefficient is 3.6 and the exponent is -6.
To convert it to standard notation:
3.6 x 10⁻⁶ = 0.0000036

Which symbol and unit of measurement are used for resistance?
symbol: R: unit :
symbol: 0; unit: R
symbol: R: unit o
symbol: R: unit R
Answer:
Unit of resistance is Ω (Omega).
Explanation:
The ability to measure the oppose the flow of electric current is called resistance of a circuit. Its relation with voltage and current is given by Ohm's law as follows :
V = IR
R is resistance
Its unit is Omega and it is represented by Ω.
The unit of the electrical resistance is ohm Ω
The symbol of resistance is R.
Hence Option A) Symbol: R, Unit : Ω is the correct answer
What is resistance?Resistance is simply the measure of the opposition to current flow in an electrical circuit.
Ohm’s law states that the potential difference between two points is directly proportional to the current flowing through the resistance.
V = I × R
Where;
V is the voltage or potential difference. I is the current.R is the resistance.The unit of the electrical resistance is ohm Ω
The symbol of resistance is R.
Hence Option A) Symbol: R, Unit : Ω is the correct answer

Create a sort of infomercial featuring a solution you created or designed.
Say a few statements about it.
please help
Answer:
Informercials, like the class Shamwow Informercial are an example of how structure and technique can have a huge effect on how a user or prospect is driven towards taking a specific action like clicking a buy button.
Informercials follow a specific structure that any small business can use to drive action but few businesses ever consider using it when they pitch their product or service. In this post, we'll describe the structure and give you examples of how you can use it in your business.
The question above wants to test your ability to create an infomercial using your creativity. For that reason, I can't create an infomercial for you, but I'll show you how to create one.
First, you need to know that an infomercial is an advertisement made to be played on television, usually associated with sales, but can be used to present information.
Based on this, you should create your newsletter as follows:
Establish the element that your infomercial wants to present.Show what are the issues related to this element.Show the solutions you want to present to these problems.Show how these solutions are truthful and reliable.In the image below, you can see a tutorial on how to make an infomercial.

Selena is learning about how engineers choose metals for spacecraft. She discovers that spacecraft engineers often mix other metals with titanium. Titanium is a metal that is both lightweight and strong. It also resists corrosion. Selena wants to compare titanium with other metals. She looks at the cell from the periodic table that represents titanium.
Explain what each of the four items in the cell represents. Then, classify titanium as an alkali, alkali earth, or transition metal.
Ti is a transition metal.
Further explanationChemical symbol represent element or compound
The elements are arranged in the periodic system
1. 22This is the atomic number of Titanium
The Atomic Number (Z) indicates the number of protons of an element
2. TiThis is the symbol (chemical formula) of titanium
3. 47.90This is the mass number of Titanium
Mass Number (A) = Number of protons + Number of Neutrons
Atomic Number (Z) = Mass Number (A) - Number of Neutrons
4. TitaniumThis is the name of the element
To determine which group, alkaline, alkaline earth or transition it can be seen from the electron configuration
alkali and alkali earth : configuration from orbital 1s-7s
transition : configuration from orbital 3d-6d (Block d)
Electron configuration from Ti : [Ar] 3d²4s²
if we look at the configuration, then Ti is in the d block which is included in the transition metal
