AWES TGT Physics Mock Test - 9 - AWES TGT/PGT MCQ

The Indian Meteorological Department (IMD) conducted the Pre-Cyclone Exercise to assess preparedness for the upcoming cyclone season, reflecting their ongoing commitment to disaster management and public safety as they celebrate their 150th year of service.

The Union Ministry of road transport and highways is planning to extend its Incident Management Services (IMS) to all national highways.
The purpose of this step is to minimize road fatalities and improve safety for road users. Incident Management Services (IMS) on national roads will be provided, run, and maintained by businesses.

All the three sentences are correct. Teaching aids, when used moderately, enhance teaching efficiency. Use of teaching aids fosters motivation and they also emphasise learning by doing. Teaching aids are a means of enhancing learning without boredom and keeping the students engaged. So, they are a very important teaching tool.

Psychologist Albert Bandura is the researcher most often associated with learning through observation. He and others have demonstrated that we are naturally inclined to engage in observational learning.

Hearing impairment refers to hearing loss that prevents a person from totally receiving sounds through the ear. If the loss is mild, the person has difficulty hearing faint or distant speech. 

• Hearing is one of the five senses. Most normal-hearing persons do not fully appreciate the significance of the sense of hearing, and often, do not understand the difficulties faced by the hearing impaired.
• People who are born with hearing impairment, do not learn to speak by themselves, as others do but they can easily move from one place to another and take care of themselves.

Key Points

Language and Speech Development Barrier in Children with Hearing Impairment

• Hearing impairment is a great barrier to the normal development of language; the child with such impairment is at a severe disadvantage in virtually all aspects of language development.
• A considerable number of educators of deaf individuals believe that many of the problems of people who are hearing-impaired related to social and intellectual development are primarily due to their deficiencies in language.
• When the child meets other hearing-impaired children and realizes other people face similar challenges and manage fine, regardless of language or level of hearing, it supports identity development and increases confidence.

Additional Information

• For a child with visual impairment, then the teacher has to ensure that besides visual strategies, he/she also explains orally and uses models that the child can explore by tactile sense.

Hence, we can conclude that Hearing-impaired children exhibit barriers to communication by language.

The resultant of these two forces is  .Now 

Weight becomes zero in a freefall or when the total force on your body is zero. For example, in a freely falling lift the contact force on your body is zero, so the weighing​ machine would show zero reading. So you are weightless.

Gamma-ray photons have the highest energy in the EMR spectrum and their waves have the shortest wavelength. Scientists measure the energy of photons in electron volts (eV). X-ray photons have energies in the range 100 eV to 100,000 eV (or 100 keV). Gamma-ray photons generally have energies greater than 100 keV.

Torque is the rate of change of angular momentum. Force in linear motion corresponds to torque in rotary motion. Thus, just as Newton’s second law can be written as F = dP/dt (F for linear motion), it can be written as T = dL/dt for rotary motion.

To find the characteristic temperature using Wien's displacement law, we start with the formula λ_m T = 0.29 cmK. We need to convert the wavelength λ_m from meters to centimeters: λ_m = 5×10^-7 m = 5×10^-5 cm. Substitute this into the formula: T = 0.29 cmK / 5×10^-5 cm, which gives T = 5800 K. Due to rounding and context of black body radiation, this temperature is closer to 6000 K. Thus, the characteristic temperature range is approximately 6000 K.

The newton second (also newton-second, symbol N s or N.s) is the derived SI unit of impulse. It is dimensionally equivalent to the momentum unit kilogram metre per second (kg.m/s). One newton second corresponds to a one-newton force applied for one second.

Using Hooke ‘s Law we get

Stress directly proportional to stress = Load/Area=F/pie*r*r

And rp:rq=2:1

When both the wires are under the same stress,strain produced will be the same.
 

When both the wires are under the same stress,strain produced will be the same.

2.when both the wires are loaded by same weight then

Strain p/strain q=(rq)²/(rp)²=¼

Moment of inertia =1/2​×mass×(Radius of gyration)²=[M¹L²T⁰]
Moment of force = torque =N.m=[M¹L²T⁻²]
Both are different from each other.

The maximum current can be drawn from a cell if the external resistance R = 0.

When current is to be drawn at max then the conducting wire rating comes high such that resistance is less.

Resistance R = rho x l/a

Rho = resistivity constant

L=length

a=area of cross-section

Hence, if the area of cross-section increases resistance decreases by increasing the rate of current to flow.

The voltage in India is 220 volts, alternating at 50 cycles (Hertz) per second. This is the same as, or similar to, most countries in the world including Australia, Europe and the UK. However, it's different to the 110-120 volt electricity with 60 cycles per second that's used in the United States for small appliances.

Plane (a small area on the surface of a large sphere is nearly planar). The portion of the wavefront of light from a distant star intercepted by the Earth is a plane.

Area of magnification, 
A₁​A₂=μ²
A₁/6​​=100
A_1​=600 cm²

Acceleration (a) = 9.8 m/s²

Weight of the body = 9.8 N

Since, Weight of the body = mg

⇒ Mass = Weight/g = 9.8/9.8 = 1 kg

We know that,

F = m × a

⇒ F = 1 kg × 9.8 m/s²

⇒ F = 9.8 Newton

Beyond the elastic limit, if still some force is applied to the body, at first the body deforms completely and when it can’t deform more, it starts to break into pieces. Now when the plastic range is small, on less extent of applied external force the body would break. And we know such objects are called brittle.

Bernoulli's principle can even be derived from the principle of conservation of energy. Bernoulli's principle states that, in a steady flow, the sum of all forms of energy in a fluid along a streamline is the same at all points on that streamline.
Hence D is the correct answer.

As one coil is wound over the other so that coupling is tight i.e. k=1

for an approximate result, divide the length value by 1.609

► One kilometer is equals to 0.62 miles.

It is because at every point of circle an object has two acceleration (Tangential & Angular acceleration).At every point a body experience a tangential force which is perpendicular to the radius of the circle, when the string breaks the centripetal force disappear ( the radially inward force which holds a body in a circular motion) Hence the only Tangential force act on the body & it goes in that way.

Bernoulli’s theorem, in fluid dynamics, relation among the pressure, velocity, and elevation in a moving fluid (liquid or gas), the compressibility and viscosity (internal friction) of which are negligible and the flow of which is steady, or laminar. First derived (1738) by the Swiss mathematician Daniel Bernoulli, the theorem states, in effect, that the total mechanical energy of the flowing fluid, comprising the energy associated with fluid pressure, the gravitational potential energy of elevation, and the kinetic energy of fluid motion, remains constant. Bernoulli’s theorem is the principle of energy conservation for ideal fluids in steady, or streamline, flow and is the basis for many engineering applications.

Using Ampere’s law at a distance r from axis, B is same from symmetry.

Here i is zero, for r < R, whereas R is the radius

∴B = 0
