Short answer📘 N.VM.A.3🧠 DOK 1

Question:

A car is traveling north at a speed of 30 miles per hour. Another car is traveling east at a speed of 40 miles per hour. Assuming these are vector quantities, calculate the magnitude of the resultant velocity of the two cars.

✅ Answer:
The magnitude of the resultant velocity is 50 miles per hour.

💡 Explanation:

  • To find the magnitude of the resultant vector when two vectors are perpendicular, use the Pythagorean theorem: (302+402)=(900+1600)=2500=50\sqrt{(30^2 + 40^2)} = \sqrt{(900 + 1600)} = \sqrt{2500} = 50.

  • Thus, the magnitude of the resultant velocity is 50 miles per hour.

Question:

Which of the following substances is expected to have the strongest electrical forces between its particles based on its structure at the bulk scale?

Answer Choices:

  • A) A. Sodium chloride (NaCl)
  • B) B. Water (H2O)
  • C) C. Carbon dioxide (CO2)
  • D) D. Methane (CH4)
✅ Answer:
A. Sodium chloride (NaCl)

💡 Explanation:

  • Sodium chloride (NaCl) forms an ionic compound with a crystalline lattice structure, resulting in strong electrical forces between its particles.
  • In contrast, water, carbon dioxide, and methane have covalent bonds with weaker intermolecular forces.

Short answer📘 8.NS.A.1🧠 DOK 3

Question:

Explain why the decimal expansion of the number 2 \sqrt{2} is considered irrational, and provide an example of a rational number with its repeating decimal expansion. Then, demonstrate how to convert this repeating decimal into a fraction.

✅ Answer:

The decimal expansion of 2 \sqrt{2} is irrational because it is non-repeating and non-terminating. An example of a rational number is 13 \frac{1}{3} , which has a repeating decimal expansion of 0.333... To convert 0.333... into a fraction, let x=0.333... x = 0.333... . Then, 10x=3.333... 10x = 3.333... . Subtracting these equations gives 9x=3 9x = 3 , so x=13 x = \frac{1}{3} .

💡 Explanation:

  • Irrational numbers have decimal expansions that neither terminate nor repeat.

  • The decimal representation of 2 \sqrt{2} , approximately 1.414213..., does not repeat.

  • Rational numbers, however, have decimal expansions that either terminate or repeat.

  • For instance, \( \frac{1}{3} = 0.333...

  • \) repeats the digit 3.

  • By setting \( x = 0.333...

  • \), multiplying both sides by 10, and solving the resulting equation \( 10x - x = 3.333...

  • - 0.333...

  • \), we find x=13 x = \frac{1}{3} .

Question:

Analyze the leadership qualities and decisions of George Washington during the American Revolution and his presidency that were crucial in establishing American democracy. Discuss specific examples and their significance.

✅ Answer:
George Washington's leadership during the American Revolution and his presidency was pivotal in establishing American democracy. During the American Revolution, his role as the Commander-in-Chief of the Continental Army demonstrated his ability to unify and motivate the troops despite facing numerous hardships. His decision to cross the Delaware River for a surprise attack on Hessian forces in Trenton was a turning point that boosted morale and support for the revolutionary cause. As the first President of the United States, Washington set precedents by establishing a cabinet and delivering a Farewell Address that warned against political factions and foreign alliances, emphasizing unity and neutrality. His voluntary step down after two terms set an example of peaceful transition of power, reinforcing democratic principles and preventing the emergence of a dictatorship.

💡 Explanation:

  • Washington's leadership was characterized by strategic military decisions and a commitment to democratic principles.
  • His actions during the revolution, such as the crossing of the Delaware, demonstrated his tactical acumen and ability to inspire his troops.
  • As president, his establishment of executive protocols and his voluntary departure after two terms underscored his dedication to democracy, setting a lasting standard for future leaders.
