A. Objective The learners should be able to investigate changes that happen in the absence of oxygen. B. Materials ● fire. Activity: TITLE: ABSENCE OF OXYGEN Jar with cover (Jar A) Jar without cover (Jar B) 2 same sized candle (small) Match or lighter Timer Ruler C. Precautionary Measure Remember to handle match or lighter carefully and don't play with it for it can cause D. Procedure 1. Label the jar with cover with Jar A and the jar without cover as Jar B. 2. Light the candles with a match and put the candles in each jar. 3. Record the time when the candles are lighted and the time when the light was put off. 4. Cover the Jar A and observe what will happen. 5. Measure the length of the candles after the flame was put off. 6. Record your findings on the chart below. Jars JAR A JAR B Time of the flame was put off Length of the candle after burning Answer the following questions: 1. Which of the 2 jars was the candle's flame put off first? 2. Which of the two candles has the shortest size? 3. What happen, when you cover the Jar A? 4. When the lighted candle in Jar A was covered, the flame was put off, what is the reason why the candle's flame did not continue to burn? 5. What are the 3 main components in combustion? Doss​

In other words, the object that experience a greater impulse is the one that has the greater change in momentum. Situation 2: A basketball and ping pong ball collided having the same velocity but different mass. a. Which ball has a lesser momentum? b. Which ball has a greater impulse? Situation 3: Two marbles collide. Marble A has greater mass and velocity while Marble B has smaller mass and velocity. a. Which has a greater momentum- marble A or B? b. Which marble has a greater impulse? c. Which marble would you think will be thrown away? d. Why? Figure 2.3. Collision between a basketball and a ping pong ball. Illustrated by Michelle M.

Answer:

❤️

Explanation:



Situation 2:
a. The basketball has a lesser momentum because momentum is directly proportional to mass, and the basketball has a greater mass than the ping pong ball.
b. The basketball has a greater impulse because impulse is equal to the change in momentum, and the basketball experiences a greater change in momentum due to its greater mass.

Situation 3:
a. Marble A has a greater momentum because momentum is directly proportional to both mass and velocity, and Marble A has both greater mass and velocity compared to Marble B.
b. Marble A has a greater impulse because impulse is equal to the change in momentum, and Marble A experiences a greater change in momentum due to its greater mass and velocity.
c. Marble B would be thrown away because it has less momentum compared to Marble A.
d. Marble A has greater momentum and therefore imparts more force on Marble B during the collision, causing Marble B to be thrown away. Additionally, Marble A experiences a greater change in momentum, resulting in a greater impulse that pushes Marble B away with more force.
