Question Discussion & Solution

The Correct answer is Uniform motion.

Key Points

• Motion​:
  • It is a phenomenon in which an object changes its position with respect to time.
  • All motions are relative to some frame of reference. 
  • There are two types of motion:
    • Uniform Motion
    • Non-uniform Motion
• Uniform motion:
  • If an object is traveling with uniform motion, it is moving in a straight line at a constant speed.
  • For example, An object falling at terminal velocity experiences the same air resistance as its weight.
  • Newton's first law can be used to explain the movement of objects traveling with uniform motion.
  • Newton's first law is a body that is at rest or moving at a uniform rate in a straight line will remain in that state until some force is applied to it.

​Additional Information

• Retarding motion: The Motion in which the speed of the body gradually decreases.
• Non-uniform motion: If a body covers unequal distances in equal intervals of time
• Non-linear Motion: Nonlinear motion is motion along a curved path; It is the combination of two components of motion' horizontal motion (without acceleration) vertical motion (under the acceleration of gravity).

Concept

The javac command in Java compiles a program from a command prompt.

It reads a Java source program from a text file and creates a compiled Java class file.

Syntax

javac filename [options]

For example, to compile a program named Abc.java, use this command:

javac Abc.java

The correct answer is Only I.

Key Points

• In asexual reproduction, only one parent is involved and sex cells are not involved. 
• It is observed in both multicellular and unicellular organisms.
• Types of asexual reproduction are:
  • Binary Fission
  • Budding
  • Fragmentation
  • Vegetative Propagation
  • Sporogenesis
• Spore formation comes under sporogenesis. Hence, statement 1 is correct.
• Spore formation is a kind of reproduction process in plants by produces tiny spores and propagates through them.
• Spore Formation is a method of asexual reproduction. 
• Spore formation can be seen in the bread mould / Rhizopus.
• The airborne spores land on bread under favourable conditions and they germinate and produce new bread mould plants.
• Each spore is covered with a protective coat to withstand unfavourable conditions.
• Plants like ferns, mucor, and mosses are also reproduced through spore formation
• Spores are present in a sac called sporangia.
• Fragmentation is a type of asexual reproduction. Hence, statement 2 is incorrect.

Additional Information

• Pollination is a method of Sexual Reproduction.
• Self-pollination:
  • The transfer of pollen grains from another to the stigma of the same flower is called self-pollination.
• ​Cross-pollination:
  • The transfer of pollen grains from the anther of one flower to the stigma of another flower is called cross-pollination.
• Vegetative propagation:
  • It is a form of asexual reproduction of a plant wherein a new plant grows from a fragment of the parent plant.

Just as Needle is a part/component of the Clock, similarly Blade is a part/component of Fan.

Thus the related word pair is Fan : Blade.

The correct answer is Nahargarh Fort.

Key Points

• Nahargarh Fort:
  • It was built by the Kachwaha dynasty's Sawai Jai Singh in 1734 AD.
  • It is also known as Sudarshangarh Fort, which is the original name of Fort.
  • Its other names are- Jaipur's Crown, Palace's Fort, and Meethadi's Fort.
  • Sawai Madho Singh 2nd built 9 palaces for his 9 Paswan.
  • The name of Palaces are Suraj Prakash, Khushhal Prakash, Jawahar Prakash, Lalit Prakash, Chand Prakash, Anand Prakash, Lakshmi Prakash, Phool Prakash and Basant Prakash.
  • These Palaces were built in Victorian Style.

Additional Information

• Mawatha Lake is Situated In Amer Fort. 
  • it was built by Mirza Jai Singh in 1664 AD.
