If the velocity of a body is reducing, it is said to have- a)Negative acceleration
- b)Retardation
- c)Positive acceleration

|
EduRev Class 9 answered |
The correct answer is D: Both (a) and (b).
- Acceleration is the rate of change of velocity. It can be positive (increasing velocity) or negative (decreasing velocity).
- Retardation is another term specifically used for negative acceleration. It describes a situation where the velocity is slowing down.
Therefore, when the velocity of a body is reducing, it has both:
- Negative acceleration: Because the change in velocity is negative.
- Retardation: Because it's the specific term for negative acceleration in the context of slowing down.

Rukmini Iyer answered • Feb 02, 2025 |
Understanding the Intruder's Behavior
The intruder's behavior can indeed be characterized as harsh, primarily due to his threatening demeanor.
Key Aspects of the Intruder's Harsh Behavior:
- Threatening Language:
- The intruder uses aggressive commands like "put those paws up!" which indicates a demand for compliance through intimidation.
- Implie... more
- Phrases such as "I'll make you crawl" suggest a willingness to inflict harm or humiliation, reinforcing his threatening approach.
- Control and Intimidation:
- The intruder's intention to extract information through fear highlights his desire for control, which is a hallmark of harsh behavior.
Comparison with Other Options:
- Aggressive Physical Actions:
- Option (a) mentions throwing things, which is a physical act but isn't specified in the extract; thus, it lacks evidence.
- Loudness:
- Option (b) refers to shouting, which is not demonstrated in the extract. The intruder's speech is forceful but not described as loud.
- Continuous Abuse:
- Option (c) suggests ongoing verbal abuse, yet the dialogue does not indicate continuous insults, focusing instead on threats.
Conclusion:
The intruder's behavior stands out as harsh primarily because of his threatening manner of speaking. His use of intimidating language and commands effectively creates a sense of fear and control over Gerrard, which establishes the severity of his actions.

Rukmini Iyer answered • Nov 17, 2024 |
Understanding Modals
Modals are auxiliary verbs that express necessity, possibility, ability, permission, or ability. They are essential for creating nuanced meanings in sentences.
Types of Modals
- Can: Indicates ability or possibility.
- Could: Past ability or polite requests.
- May: Expresses permission or possibility.
- Mig... more Suggests a lower possibility.
- Must: Indicates necessity or strong obligation.
- Should: Suggests advice or recommendation.
- Will: Indicates future intention.
- Would: Polite requests or hypothetical situations.
Using Modals in Fill in the Blanks
When using modals in fill-in-the-blank exercises, consider the context of the sentence. Here are some tips:
- Identify the Context: Understand what the sentence is conveying—necessity, permission, ability, or possibility.
- Choose the Right Modal: Based on the context, select the appropriate modal. For example, if the sentence requires expressing ability, "can" or "could" might be suitable.
- Pay Attention to Tense: Some modals indicate past or present actions. Use "could" for past ability and "can" for present ability.
- Consider Politeness: For requests or suggestions, using "could" or "would" can convey politeness.
Examples
- "She ___ swim very well." (Answer: can)
- "You ___ finish your homework before dinner." (Answer: must)
- "We ___ go to the park tomorrow if it doesn't rain." (Answer: might)
By understanding the context and function of modals, you can accurately complete fill-in-the-blank exercises.
