S6: The conclusion is clear: force not only depends on the change in momentum, but also on how fast the change is brought about.
P: The novice, on the other hand, keeps his hands fixed and tries to catch the ball almost instantly.
Q: One reason is that the seasoned cricketer allows a longer time for his hands to stop the ball.
R: Consequently, he needs to provide a much greater force to stop the ball instantly, and this hurts.
S: He does this by drawing his hands backward in the act of catching the ball.
Cricket Ball Catching Physics
The question requires arranging four jumbled sentences (P, Q, R, S) to form a coherent paragraph, given the first (S1) and last (S6) sentences.
Jumbled Sentences Analysis
Let's analyze the function of each sentence:
- S1: Introduces the scenario: a seasoned cricketer catches a fast ball easily, while a novice might get hurt.
- S6: Provides the underlying physics principle: force depends on the rate of momentum change (\(F = \frac{\Delta p}{\Delta t}\)).
- Q: Explains the seasoned cricketer's ease by stating they allow a longer time for the ball to stop.
- S: Details the action the seasoned cricketer takes to achieve this longer stopping time: drawing hands backward.
- P: Contrasts the novice's method: keeping hands fixed and stopping the ball instantly. The phrase "on the other hand" signals this contrast.
- R: Explains the consequence of the novice's method: a much greater force is needed to stop instantly, causing pain and injury.
Sequence QSPR Logic
The logical progression is as follows:
- S1 sets the context comparing a skilled player and a beginner.
- Q provides the reason for the skilled player's success: increasing the time duration (\(\Delta t\)) to stop the ball.
- S describes the technique used to increase this time (\(\Delta t\)).
- P introduces the beginner's contrasting technique: minimizing the time (\(\Delta t\)) for stopping the ball.
- R explains the outcome of the beginner's technique: a larger force (\(F\)) is required due to the shorter time, causing hurt.
- S6 concludes by stating the physics law that validates this observation: force (\(F\)) is inversely proportional to the time interval (\(\Delta t\)) for a given change in momentum (\(\Delta p\)).
Thus, the correct sequence for the jumbled sentences is QSPR.
Final Paragraph and Physics Explanation
The complete, logical paragraph is formed by S1-Q-S-P-R-S6. This sequence clearly illustrates the concept of impulse, showing that applying the same change in momentum over a longer time requires less force, thereby preventing injury, as demonstrated by the seasoned cricketer.
Similar Questions
- S1: The primary evidence for climate change that occurred many million years ago is the rocks and deposits themselves.
S6: In other words, despite the clear legacy in many parts of the world of recent glaciation, the vast majority of sedimentary rocks were laid down in warm climatic conditions.
P: Sediments and fossil in the poles tell us a great deal about the environment in which they were laid down.
Q: We must, of course, bear in mind when interpreting this information that, because of the movement of the continents, no one latitude of the Earth has necessarily gone through such marked climatic vicissitudes.
R: Nevertheless, even allowing for this factor, one of the most remarkable discoveries about the climate change of the past is that the two poles of the Earth have been free of ice for at least 90 per cent of the known history of the planet.
S: We may find in close proximity to one another, coal deposits indicating the humid conditions of the tropics, red sandstones laid down in deserts and morainic materials reflecting polar conditions. - S1: Temperature indicates the relative degree of molecular activity, or heat, of a substance.
S6: The boiling point of water under standard conditions is at 100 degrees Centigrade.
P: Temperature is an index of sensible heat, not a direct measure of the quantity of energy.
Q: Zero on this scale is the 'triple point' temperature, at which the gaseous, liquid, and solid states of water are at equilibrium under standard atmospheric pressure.
R: If heat flows from one body to another, the former has the higher temperature.
S: To indicate the temperature of a body, an arbitrary scale of reference is employed. (P) its policy and announced reforms
