The ratio of 1 hour to 300 seconds is:

• To compare time, we should convert both times to the same unit. Let's convert 1 hour to seconds (since 1 hour = 3600 seconds).
• 1 hour = 1 × 3600 seconds = 3600 seconds
• Now we have 3600 seconds to 300 seconds. The ratio is  3600 : 300.
• To simplify, divide both by their greatest common divisor, which is 300.
• 
• So, the ratio is 12 : 1, which corresponds to option (b).

Number of Hosts That Can Successfully Send Data Simultaneously on Ethernet
There are certain limitations to the number of hosts that can successfully send data simultaneously on Ethernet. The answer to this question is:
Answer: B. 2
Explanation:
Ethernet is a widely used technology for local area networks (LANs) and it uses a shared medium for communication. The number of hosts that can send data simultaneously on Ethernet is limited due to the following reasons:
1. Collision Domain: In Ethernet, all devices connected to the same network segment share the same collision domain. A collision occurs when two or more devices transmit data at the same time, resulting in data corruption. To avoid collisions, Ethernet uses a carrier sense multiple access with collision detection (CSMA/CD) mechanism. This means that only one device can successfully transmit data at a time, while others must wait for their turn.
2. Half-Duplex Mode: Ethernet operates in either half-duplex or full-duplex mode. In half-duplex mode, a device can either transmit or receive data at a given time, but not both simultaneously. Therefore, only two hosts can communicate at the same time - one sending and the other receiving.
3. Bandwidth Sharing: Ethernet shares the available bandwidth among all the connected devices. If multiple hosts try to transmit data simultaneously, the available bandwidth gets divided, resulting in lower throughput for each host. To ensure efficient data transmission, it is recommended to limit the number of hosts sending data simultaneously.
In summary, due to the collision domain, half-duplex mode, and bandwidth sharing, Ethernet allows only two hosts to successfully send data simultaneously.

Print Chart:

• A: Refers to a printed chart.


• B: Indicates a chart that is filled in by an analyst while formatting a report.


• C: Describes a chart that is prepared by users.


• D: States that the chart is printed by a computer.

The correct answer is B, as it specifically mentions that the chart is filled in by an analyst while formatting a report. Let's further explain each option:
A: A printed chart: This option refers to a chart that has been physically printed, but it does not specify who prepares or fills in the chart.
B: One which is filled in by an analyst while formatting a report: This option explicitly states that the chart is filled in by an analyst during the process of formatting a report. This suggests that the chart is part of the report and is completed by an analyst with the necessary data.
C: Prepared by users: This option indicates that the chart is prepared by users, but it does not mention who these users are or how the chart is used in the context of a report or formatting.
D: Printed by computer: This option suggests that the chart is printed by a computer, but it does not provide any information about who creates or fills in the chart.
In conclusion, the correct option is B as it clearly specifies that the chart is filled in by an analyst while formatting a report.

Answer: C

Explanation:
The word that is different from the rest is Scallop (C). The reasons are as follows:
- Oyster (A), Clam (B), and Mussel (D) are all bivalve mollusks, meaning they have a shell that is divided into two hinged parts. On the other hand, Scallop (C) is also a bivalve mollusk, but it has some unique features that set it apart.
- Scallop's unique features:
- Scallops have a distinct shell shape, which is rounder and flatter compared to the other three.
- Scallops have an ability to swim by opening and closing their shells rapidly, which is not a common feature among the other three mollusks.
- The adductor muscle of the scallop, the part that is commonly consumed, is larger and more developed than in oysters, clams, or mussels, making it a more popular choice for culinary dishes.
These differences make Scallop (C) the word that stands out from the rest.All except Scallop, live in shells.

X-ray wavelength is in range of 10−11m to 10−8m

So option C is correct.

Here,number of electron,
n = 10000000 = 10⁷
Total charge on ten million electrons is
Q = ne [where e = 1.6 × 10⁻¹⁹C]
=10⁷ × 1.6 × 10⁻¹⁹C = 1.6 × 10⁻¹²C
Time taken by ten million electrons to pass from point P to point Q is
t = 1μs = 10⁻⁶s
The current
I = 
Since the direction of the current is always opposite to the direction of flow of electrons. Therefore due to flow of electrons from point P to point Q the current will flow from point Q to point P.

Electric dipole at rest can be considered as charge particles at rest. hence, no magnetic field is applied on it.

3/2=v/u…...1
2/3=(v-16)/(u+16)......2
from these equation
we get v=48, u=32
so now f=(vxu)/(v+u)=96/5=19.2
The correct answer is option B.

as the maximum current that can be drawn from a cell is for R =0 therefore, it is I = E/r.

The orderly distribution of electromagnetic radiations according to their wavelength or frequency as called the electromagnetic spectrum. Radio waves are electromagnetic waves of the frequency range from few Hz to 10⁶ Hz.

Frequency (v) = qB/2πm.
Frequency is independent of radius of trajectory of particle and speed of particle.
 

Critical angle will be, sin⁻¹(1/1.5) = 41.8. The angle of incidence inside the prism will be 45. Since it is more than critical angle, the light ray will be internally reflected.

In a current-carrying conductor, by varying the electric current, the magnetic field is generated. The direction of the magnetic field generated will be perpendicular to the conductor.
The direction of the magnetic field can be determined as wrapping the right-hand fingers around the wire and the direction of the current is indicated by the thumb.
Ampere’s law is used for determining the magnetic field of a long conductor:
B=μ0I/2πr
Where,

• I is the current in Amperes

• r is the radial distance in metres

• B is the magnetic field in Tesla

The correct answer is option D
Electrical resistivity (also called specific electrical resistance or volume resistivity) and its inverse, electrical conductivity, is a fundamental property of a material that quantifies how strongly it resists or conducts electric current. ... The SI unit of electrical resistivity is the ohm-meter (Ω⋅m).
 

The outermost shell configuration of the element shows 8 electrons hence it is a noble gas.

Maltose can be produced from starch by hydrolysis in the presence of the enzyme diastase. It can be broken down into two glucose molecules by hydrolysis. In living organisms, the enzyme maltase can achieve this very rapidly. In the laboratory, heating with a strong acid for several minutes will produce the same result.

The alpha helix (α-helix) is a common motif in the secondary structure of proteins and is a right hand-helix conformation in which every backbone N−H group hydrogen bonds to the backbone C=O. group of the amino acid located three or four residues earlier along the protein sequence.

For ∆H formation we have to look for following:
1. formation of "1 mole" of substance.
2. from "stable" constituting elements.

In first option 1 mole of Co₂ should be formed from C(graphite) for enthalpy of formation to be defined.
In third option 2 moles of NH₃ is formed instead of 1 mole. So incorrect.
In fourth option Co₂ is not formed from constituent elements I.e C(gr) and O2(g) so it is not enthalpy of formation.

Mixture and a compound both follow the law of conservation of mass so their weight equals to the sum of mass of their components.

cos 4x = cos 2x

r = 1, n = 5
p = 10/100  = 1/10,
q = 1 - p
q = 1 - 1/10   = 9/10
= nCr (p)^r (q)^{(n - r)}
Exactly one is defective = 5C1 (1/10)¹ (9/10)^{(5 - 1)}
= 5C1 (1/10) (9/10)⁴
= (1/2) (9/10)⁴

As per the definition of LPP:
Linear Programming Problem is one that is concerned with finding the optimal value of a linear function of several variables, subject to the conditions that the variables are non-negative and satisfy a set of linear inequalities.
Since the variables (x & y) are non-negative, the feasible solution of a LPP belongs to the 1st quadrant only.

 f(x) = a^x
Taking log bth the sides, log f(x) = xloga
f’(x)/a^x = loga
f’(x) = a^x loga   {a^x > 0 for all x implies R, 
for loga e<a<1 that implies loga < 0}
Therefore, f’(x) < 0, for all x implies R
f(x) is a decreasing function.

2x - y +3z + 4 = 0
x - 3y + z = 0
x + 2y + z + 1 = 0
x = 12/5
y = -1/5
z= -3
this point also satisfied by
ax - y + z + 2 = 0
a(12 / 5) - (-1/5) + (-3) = 0
⇒ 12a/5 + 1/5 -3 = 0
a= -2
