Answer:

The Hall effect is the phenomenon in which a voltage difference (called the Hall voltage) is produced across an electrical conductor, transverse to the conductor’s electric current when a magnetic field perpendicular to the conductor’s current is applied.

When a magnetic field is present that is not PARALLEL to the motion of moving CHARGES within a conductor, the charges experience the Lorentz force. In the absence of such a field, the charges follow a roughly straight path, occasionally colliding with impurities.

In the presence of a magnetic field with a perpendicular COMPONENT, the PATHS charges take becomes curved such that they accumulate on one face of the material. On the other face, there is an excess of opposite charge remaining. Thus, an electric potential is created so long as the charge flows. This opposes the magnetic force, eventually to the point of cancelation, resulting in electron flow in a straight path.

Thermogram :- A PHOTOGRAPHIC record made by thermography.

• These are actually visual displays of the amount of INFRARED energy emitted, transmitted, and REFLECTED by an OBJECT.

• Because there are MULTIPLE sources of the infrared energy, it is difficult to get an accurate temperature of an object using this method.

• These are Thermal Images .

Answer:

In ELECTROMAGNETISM, ELECTRIC FLUX is the MEASURE of the electric field through a given surface, although an electric field in itself cannot flow. It is a way of describing the electric field strength at any distance from the charge causing the field.

Answer:

In physics, magnitude MEANS greatness of size or extent. A vector has a magnitude and a DIRECTION, its magnitude being the NUMERICAL value of its LENGTH, size or quantity. A scalar in physics is defined by magnitude or quantity and not by direction.

ANSWER:

UNIFORM ACCELERATION (OPTION A).

Explanation:

WHEN A STONE IS DROPPED FROM A CERTAIN HEIGHT THE VELOCITY INCREASES AT 9.8 M/S DUE

GRAVITATIONAL ACCELERATION OF 9.8 M/S^2

AND IT CONTINUES TO BE IN ACCELERATED MOTION TILL IT TOUCHES THE GROUND AND VELOCITY AND ACCELERATION BECOME 0.

YES IT IS IN UNIFORM ACCELERATION COZ ITS VELOCITY IS INCREASING AT THE RATE OF 9.8M/S

IN EVERY SECOND.

Explanation:

Charge invariance refers to the fixed electrostatic potential of a particle, REGARDLESS of speed. For example, an ELECTRON has a SPECIFIC REST charge. Accelerate that electron, and the charge remains the same (as opposed to the RELATIVISTIC mass and energy increasing). The key word here is relativistic.

The correct option is (a)Both A and R are true, and R is the correct explanation of A.

• Eukaryotic cells can EASILY adopt various shapes and also perform some guided movements.
• This is because they have a network of protein fibers that support the SHAPE of the cell and anchor the organelles to a fixed position. This is called the cytoskeleton network.
• Within the cell the cytoskeleton consists of three elements. These are the microtubules, which CONSIST of tubulin protein, microfilaments having actin, and intermediate filaments CONSISTING of structural proteins like desmin and keratin.

• Displacement of farmer at the end of 2 minutes and 20 seconds

• Side of square FIELD = 10m
• farmer moves along the boundary of a square field of side 10m in 40s.

we know that,

☘️ perimeter of square = 4 × side

⪼ perimeter of square = 4 × 10

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀ ⠀⠀= 40m

Time taken by farmer to cover 40m = 40s

So,

In 1 second the farmer covers 1meter distance.

Now,

Distance covered by the farmer at the end of 2 minutes and 20 seconds:-

Time = 2minute 20 second

Converting 2 minutes into seconds:-

= 2 × 60 + 20

= 120 + 20

= 140 second

As we know that, the farmer covers 1m distance in 1 sec ,

So,

Distance covered by the farmer at the end of 2 minutes and 20 seconds is :-

= 1 × 140

= 140M

So,

The farmer will cover 140m distance in 2 minutes and 20 seconds.

Now,

Number of rotation the farmer takes to cover the distance

= Total Distance/perimeter

= 140/40

= 3.5

If the farmer stars from A( initial POSITION) then after 3.5 rounds he was at point C.

Therefore, Displacement is AC.

● By using Pythagoras theorem,

• AC² = AB² + BC²

➛ AC² = 10² + 10²

➛ AC² = 100 + 100

➛ AC² = 200

➛ AC = √200

➛ AC = 10√2

• ● AC = 14.14m

Hence Displacement of farmer at the end of 2 minutes and 20 seconds is 14.14m

Explanation:

On a daily basis, we walk, we run, we play, we SIT or stand. In all of these ACTIVITIES, we are changing the state of motion. We are bringing some object to rest or bringing it in motion. What is this called? What’re we actually doing? We’re actually applying ‘FORCE’ while bringing the object to rest or in motion.

Answer:

Draw a line parallel to x-axis DA from POINT, D from where object STARTS MOVING. Draw another line BA from point B parallel to y-axis which meets at E at y-axis. Above equation is the relation among initial vlocity (u ), final velocity (v ), acceleration (a) and time (t). It is CALLED FIRST equation of motion.

questions

Answer:

        Kinetic ENERGY is the energy an object has because of its motion.

• Applying a force requires us to do work. After work has been done, energy has been transferred to the object, and the object will be moving with a NEW constant speed. The energy transferred is known as kinetic energy, and it depends on the mass and speed achieved.
• To Calculate Kinetic Energy , here's the Formula .

                  K.E. = 1/2 mv²

Where K.E. = Kinetic Energy of the Object

               m = Mass of the Object

               V = Velocity of the Object

• Net Work Done is also can be Found by the Change of Kinetic Energy

           W = ΔK.E.     ( W = Net work Done )

Some Facts About K.E. :-

• When the velocity of an object doubles, its kinetic energy quadruples.
• Kinetic energy must always be either zero or a POSITIVE value. While velocity can have a positive or negative value, velocity squared is always positive.

• Kinetic energy is not a vector QUANTITY .

 For Example ,  A tennis ball thrown to the right with a velocity of 5 m/s, has the exact same kinetic energy as a tennis ball thrown down with a velocity of 5 m/s.

डायोड का उपयोग करके बनाया गया लॉजिक गेट सबसे सरल लॉजिक गेट है। किन्तु इसके केवल AND तथा OR गेट ही बनाये जा सकते हैं, 'इन्वर्टर' नहीं बनाया जा सकता। अतः इसे एक 'अपूर्ण लॉजिक परिवार' कह सकते हैं। इन्वर सहित सभी लॉजिक गेट बनाने में सक्षम होने के लिये किसी प्रकार के प्रवर्धक की जरूरत होगी। इसलिये 'सम्पूर्ण लॉजिक परिवार' बनाने के लिये रिले, निर्वात नलिका या ट्रांजिस्टर का प्रयोग अपरिहार्य है। बाइपोलर ट्रांजिस्टरों का प्रयोग करके बना लॉजिक परिवार रेजिस्टर-ट्रांजिस्टर लॉजिक (RTL) कहलाता है। आरम्भिक एकीकृत परिपथों में इसी का उपयोग किया गया था। इसके बाद विभिन्न दृष्टियों से सुधार करते हुए डायोड-ट्रांजिस्टर लॉजिक (DTL) और ट्रांजिस्टर-ट्रांजिस्टर लॉजिक (TTL) आये। अब लगभग सब जगह ट्रांजिस्टर का स्थान मॉसफेट (MOSFETs) ने ले लिया है जिससे आईसी कम स्थान घेरती है और काम करने के लिये कम उर्जा क्षय होती है। वर्तमान में प्रयुक्त लॉजिक परिवार का नाम कम्प्लिमेन्टरी मेटल-आक्साइड-सेमिकंडक्टर (CMOS) है।
