Write a summary of what you have learned about how incoming forces and outgoing forces are related (newton's cradle)
Answers
The relationship between incoming and outgoing forces in Newton's Cradle can be understood through the following concepts:
Conservation of Momentum: In a closed system with no external forces, the total momentum before a collision is equal to the total momentum after the collision. In Newton's Cradle, the momentum of the incoming ball is transferred through the stationary balls and eventually to the last ball, which swings outward with a momentum equal to the initial ball's momentum.
Conservation of Energy: Similarly, the total mechanical energy (kinetic and potential) in a closed system remains constant. In the context of Newton's Cradle, the kinetic energy of the incoming ball is transferred through the stationary balls, and eventually to the last ball, which swings outward with kinetic energy equal to that of the incoming ball. Potential energy is also involved as the balls swing and momentarily come to rest at their highest points.
Elastic Collisions: Newton's Cradle demonstrates nearly perfect elastic collisions, wherein both momentum and kinetic energy are conserved. In reality, some energy is lost to heat and sound, making the collisions slightly inelastic. However, the demonstration is still a useful approximation for understanding the transfer of forces.
Force Transfer: The incoming force exerted by the first ball is transmitted through the intervening balls to the last ball without causing any significant movement of the middle balls. This occurs because the balls are very close together and the time taken for the force to be transferred is minimal, allowing the middle balls to remain nearly stationary.
In summary, Newton's Cradle demonstrates the relationship between incoming and outgoing forces through the principles of conservation of momentum and energy, elastic collisions, and force transfer. The device provides a clear visual representation of these fundamental concepts in physics.
1. Using D10W and a vial of NaCl 4 mEq/mL, how many mL of NaCl are needed to prepare 250 mL of a
D10/NS solution?
a. 4.8mL
b. 9.6ml
c. 19.6mL
d. 154mL
Answers
To prepare 250 mL of a D10/NS solution using D10W and a vial of NaCl 4 mEq/mL, you would need 9.6 mL of NaCl. Normal saline (NS) contains 154 mEq/L of sodium chloride (NaCl). To prepare 250 mL of NS, you would need 250 mL * (154 mEq/L) = 38500 mEq of NaCl. Since the vial of NaCl contains 4 mEq/mL, you would need 38500 mEq / (4 mEq/mL) = 9625 mL = 9.6 mL of NaCl. So the correct answer is b. 9.6ml.

Answer:
The vertical columns on the periodic table are called groups or families because of their similar chemical behavior.
Explanation:
All the members of a family of elements have the same number of valence electrons and similar chemical properties. The horizontal rows on the periodic table are called periods.
The groups in periodic table are vertical columns in which elements with similar properties and same number of valence electrons are classified together.
What are groups in periodic table ?In periodic table, all elements are classified into different periods and groups. The vertical columns in the table is called groups and the horizontal rows are called periods.
The elements in a group have same number of valence electrons and similar chemical and physical properties. For example lithium and sodium are first group elements and they show similarity in properties.
There are 18 groups and 7 periods in periodic table. The first two groups are pure metals. Groups from 3-12 are called transition metals. 13 to 18 group elements are nonmetals.

Answers
Answer:
Image result for explain how the burning of fossil fuels causes climate change
When fossil fuels are burned, they release large amounts of carbon dioxide, a greenhouse gas, into the air. Greenhouse gases trap heat in our atmosphere, causing global warming.
Explanation:
Answer:
Correct answer: B). Global climate is changing due to burning of fossil fuels and deforestation.
Forest holds a large amount of carbon, plants are known to absorb carbon dioxide from the atmosphere as they grow, that carbon dioxide is stored in plants in the form of carbon in plant's roots, leaves and in the soil. When trees are cut down, that stored carbon is released in the environment in the form of carbon dioxide, which accounts for approximately 18% of global greenhouse gas emission.
The burning of fossil fuel like coal, petroleum, oil, gas for the energy purpose is one of the major contributors for the rising level of carbon dioxide in the atmosphere, which leads to global warming and affect the climate.
Hence, the correct answer would be option B.
