a)
Non-periodic motion.
b)

c)
Random motion
d)
Circulatory motion
|
Gunjan Lakhani answered |
When a bullet is fired from a gun, it typically moves in a straight line in the direction of the force applied by the gunpowder's explosion. This is known as rectilinear motion, which refers to motion along a straight path.
- A: Non-periodic motion refers to motion that does not repeat at regular intervals, which could describe some random or irregular movements, but the bullet's motion is more specific.
- C: Random motion refers to motion without a definite pattern or direction, which does not apply to a bullet's path.
- D: Circulatory motion is not a term used in the context of a bullet's movement, as a bullet moves in a straight line, not in a circular path.
Therefore, the bullet exhibits rectilinear motion.
Topic in NCERT: TYPES OF MOTION
Line in NCERT: "In all these examples we see that the objects move along a straight line. This type of motion is called rectilinear motion."

a)
Nothing Specific
b)

c)

d)
The time period
|
Vp Classes answered |
The width of a bar in a bar graph does not represent any specific value. Instead, it is the length or height of the bar that indicates the frequency or quantity of the data being represented.
Key points to understand:
- The width of the bars is typically uniform across the graph.
- It is the length or height that shows the data's frequency or amount.
- Uniform spacing between bars indicates they represent distinct categories.
In summary, while the width is consistent, it is the bar's length or height that conveys the essential information in a bar graph.

Lamps X and Y are connected in series with a battery. If a third identical lamp Z is connected in parallel with X, then resistance of whole circuit reduces. Due to this, current drawn from battery will increase and bulb Y will be brighter than normal.

- Ox... more:
- Comprises about 21% of the air.
- Essential for respiration in living organisms and combustion in fires.
- Argon (Ar):
- Accounts for approximately 0.93% of the air.
- An inert noble gas, it does not engage in chemical reactions.
- Carbon Dioxide (CO₂):
- Constitutes about 0.04% of the air.
- Vital for photosynthesis in plants and plays a role in regulating Earth’s temperature.
- Other Gases:
- Includes trace amounts of gases like neon, helium, methane, and ozone.
- These gases contribute to various environmental processes.
Water Vapor
- Variable Component:
- Water vapor can make up to 1-4% of the air.
- Its concentration varies based on temperature and humidity.
Importance of Air Composition
- Supports Life:
- The presence of oxygen is crucial for the survival of animals and plants.
- Climate Regulation:
- Carbon dioxide and water vapor play significant roles in the greenhouse effect, influencing global temperatures.
- Weather Patterns:
- Variations in air composition affect weather and climate systems.
In summary, air is a complex mixture, primarily composed of nitrogen and oxygen, with smaller amounts of other gases and varying water vapor. Understanding this composition is vital for appreciating its role in the environment and supporting life.

- The sum of the angles in any triangle is indeed 180°, making Option A correct.
- A number divisible by 5 must end in 5 or 0, so Option B is correct.
- The difference between two odd numbers is always even, making Option C correct.
- However, the product of two prime numbers is not always a prime number (e.g., 3 × 5 = 15), making Option D incorrect.
