The answer is B: Dynamic Host Configuration Protocol.
Explanation:
DHCP stands for Dynamic Host Configuration Protocol. It is a network management protocol used to automatically assign IP addresses and other network configuration parameters to devices on a network.
Here is a detailed explanation of DHCP:
1. Dynamic: DHCP dynamically assigns IP addresses to devices on a network. This means that IP addresses are not manually configured on each device but are automatically assigned by the DHCP server.
2. Host: DHCP is used to assign IP addresses to hosts or devices on a network. Hosts can include computers, smartphones, printers, routers, and other network devices.
3. Configuration: DHCP not only assigns IP addresses but also provides other network configuration parameters such as subnet mask, default gateway, DNS server addresses, and lease duration.
4. Protocol: DHCP is a protocol that defines the rules and procedures for devices to communicate and obtain network configuration information from the DHCP server.
Benefits of DHCP:
- Simplifies network administration by automating IP address assignment.
- Reduces the chances of IP address conflicts.
- Allows easy reconfiguration of network settings without manual intervention.
- Supports dynamic allocation of IP addresses based on the availability in the DHCP pool.
- Provides centralized management and control of IP address assignments.
In conclusion, DHCP (Dynamic Host Configuration Protocol) is a network management protocol that dynamically assigns IP addresses and other network configuration parameters to devices on a network.

 

Types of Motherboard Expansion Slots:

 

• ISA (Industry Standard Architecture): ISA slots were used in older computer systems and offered slower data transfer rates compared to newer slots.


• PCI (Peripheral Component Interconnect): PCI slots were a standard expansion slot in computers for a long time and offered faster data transfer rates compared to ISA slots.


• ATX: ATX is not an expansion slot but rather a form factor for motherboards. It refers to the size and layout of the motherboard, specifying dimensions and mounting points for components.
   
• AGP (Accelerated Graphics Port): AGP slots were specifically designed for graphics cards and offered faster data transfer rates than PCI slots. They were commonly used in older systems before being replaced by PCI Express



 

Answer: C. ATX is not a type of motherboard expansion slot.

 

Teaching profession is a 'mission', rather than a job. A teacher may not find the affirmation of his/her career choice in salary, administrators or even the students whom he/she teaches, but he/she must believe in the uncanny ability of a good teacher to positively impact the future and to leave lasting, indelible marks on those who will one day be the leaders in all facets of society. It is this power in the hands of a teacher that translates to big responsibility. A teacher who realises these things is on a mission to empower, enable and to make a positive difference.

From newton's Ist law of motion, since there is no external force acting on the object it will remain in its original state of motion. Hence, zero force is required to keep the object moving with constant velocity.

Explanation:

If we get a curve line in the displacement – time graph, it means that the velocity of the object is changing over time. The velocity is not constant but varies at different points on the curve.

Reasoning:

A curve in the displacement – time graph indicates that the object is undergoing acceleration, which in turn means that the velocity is changing. The shape of the curve can provide information about the nature of the change in velocity.

Different Cases:

There are different cases when we can have a curve in the displacement – time graph:

• Increasing velocity: If the curve is upward sloping, it means that the velocity is increasing with time.


• Decreasing velocity: If the curve is downward sloping, it means that the velocity is decreasing with time.


• Changing acceleration: If the curve has varying slopes, it means that the acceleration is changing, and therefore, the velocity is also changing.

Conclusion:

Therefore, if we get a curve line in the displacement – time graph, the velocity is non-uniform, as it is changing over time. Option B is the correct answer.

P=1/f f=1/p. f=1/0.5 f = 2m

Hydrogen gas is released.

Mendeleev's Periodic Law states that the properties of elements are the periodic function of their relative atomic masses. Mendeleev arranged all 63 elements; which were discovered till his time; in the order of their increasing relative atomic masses in a tabular form. It is known as Mendeleev's Periodic Table.

 Used as a cleansing agent in industries and households. It finds its application in paper, textile, soap, and detergent industries.

Mass of common salt (solute) = 40g
Mass of water (soluted) = 320g
Mass of solution = 320 + 40 = 360g
Concentration of solution = M(mass of solute) / mass of solution = 40/360 x 100 = 11.11%

Changes of state are physical changes in matter. They are reversible changes that do not involve changes in matter’s chemical makeup or chemical properties. Common changes of state include melting, freezing, sublimation, deposition, condensation, and vaporization.

The solution on which the solute is more than the solvent .It is called concentrated solution. Concentrated solution is a solution that contains a large amount of solute relative to the amount that could dissolve.

Human males have 23 pairs of autosomes and XY sex chromosomes.

The correct answer is:

c) Animals reproduce only by sexual mode of reproduction

Explanation:

• While many animals reproduce sexually, some animals can reproduce asexually. Examples include hydra (budding), planaria (regeneration), and some insects and reptiles (parthenogenesis).
• Therefore, it is incorrect to say that animals reproduce only by sexual reproduction.
