Answer 1

Answer:

F = 1 N

Explanation:

F = Gm₁m₂/r² + kq₁q₂/r²

F = (Gm₁m₂ + kq₁q₂) / r²

F = [6.674(10⁻¹¹)(0.50)(0.25) + 8.988(10⁹(5(10⁻⁶))(-2(10⁻⁶))] / 0.30²

F = 0.9986666667593611111...

F = 1 N

notice that the electrostatic force by itself results in an attraction of

0.99866666666666666666... N

The gravitational force is quite negligible in this example.

The vertical component of the velocity after the given time is -9.8 m/s while the horizontal component of the velocity is 16 m/s.

The given parameters;

initial horizontal velocity, vₓ = 16 m/sinitial vertical velocity, [tex]v_y =0[/tex]time interval 1 seconds

The components of the velocity can be horizontal or vertical velocity.

The vertical component of the velocity is affected by acceleration due to gravity while the horizontal component of the velocity is not affected by gravity.

The vertical component of the velocity is calculated as;

[tex]v_y = v_0_y -gt\\\\v_y = 0 - (1\times 9.8)\\\\v_y = -9.8 \ m/s[/tex]

The horizontal component of the velocity is constant since it is not affected by gravity.

The horizontal component of the velocity = 16 m/s

Thus, the vertical component of the velocity after the given time is -9.8 m/s while the horizontal component of the velocity is 16 m/s.

Assignment SummaryIn this assignment, you will create parallel time lines describing important developments that occurred during the rise of Muslim empires and at least one other civilization.You will create a time line that shows key dates and events from the expansion of Muslim empires, including events that took place during the growth of the following empires:Early Muslim caliphates, including the Rashidun caliphate started by Ab Bakr, the Umayyad dynasty, and the Abbasid dynastyThe Ottoman EmpireThe Safavid EmpireThe Mughal EmpireYou will also create a second time line showing events that took place during the growth of another civilization between 600 CE and 1500 CE. You may choose which civilization to research and highlight. Examples include:China, including the Tang, Song, Yuan, and Ming dynastiesThe Byzantine EmpireThe Mongol EmpireBackground InformationFollowing the death of Muhammad, early caliphs expanded Muslim empires throughout the Arabian Peninsula and into the Middle East. The Umayyad dynasty extended Muslim empires west to Spain and east into Persia. The Abbasid dynasty continued to rule much of this same territory for another five hundred years.After the fall of the Abbasid dynasty, the Ottoman Empire rose in Anatolia. As the Ottoman Empire expanded, two other Muslim empires were formed in Persia and India: the Safavid and Mughal Empires. These three empires existed in parallel for two hundred years, until the Safavid and Mughal Empires ended. During this same era in world history, several other civilizations continued to expand and develop. For example, several Chinese dynasties controlled territory in East Asia. The Byzantine Empire persisted in the eastern Mediterranean region from the 4th century CE until the 15th century CE. Also, in the 13th century CE, the Mongol Empire rapidly spread across Asia and influenced Europe and the Middle East.Historians use time lines to track the order of key events in different time periods. Time lines also create opportunities to compare and contrast events that took place in different regions. Focus your time lines on one topic, such as rulers or politics. This assignment will help you practice your historical thinking skills. It will also give you an opportunity to review key information from different historical eras.MaterialsComputer with internet accessOnline interactive time line builderChart with suggested dates and events Assignment InstructionsFor this project, you will submit parallel time lines for the regions of the ancient world, and a chart containing the dates and events from the time lines.Step 1: Prepare for the project.Read through the guide before you begin so you know the expectations for this project.
