A material that does not easily transmit energy, such as electric current (see also current) or heat. Materials such as wood, plastic, and ceramics are insulators. Fiberglass is an example of a heat insulator. (Compare conductor.)

Examples of insulators include plastics, Styrofoam, paper, rubber, GLASS and dry air. The division of materials into the categories of conductors and insulators is a somewhat artificial division.

Answer:

When lift accelerates up, pseudo force acts downwards, hence it INCREASES apparent weight. [a-e]

When lift accelerates down, pseudo force acts upwards, hence it DECREASES apparent weight [b-h]

When lift moves with uniform VELOCITY there is no pseudo force, hence there is no change in weight. [c-g]

When lift falls freely, it accelerates with g downwards, CAUSING an upwards pseudo force in the frame of the lift equal to mg. Hence TOTAL force is 0. So weight is 0. [d-f]

• Superconductivity is a SET of physical properties observed in certain materials where ELECTRICAL resistance vanishes and magnetic FLUX fields are EXPELLED from the MATERIAL. Any material exhibiting these properties is a superconductor.

Given:

A sprinter starts from REST and uniformly accelerates at a RATE of 2 m/s² for 5.0 seconds.

To find:

Final velocities of man ?

Calculation:

Since the acceleration is constant, we can easily apply the equations of KINEMATICS in order to solve this question.

• Let final velocity be v, INITIAL velocity be U, acceleration be a and time be t.

Applying 1st Equation of Kinematics:

So, final velocity of sprinter is 10 m/s.

ANSWER:

In physics, a FORCE is any INTERACTION that, when unopposed, will change the MOTION of an object. A force can cause an object with mass to change its velocity, i.e., to accelerate. Force can also be described intuitively as a push or a PULL. A force has both magnitude and direction, making it a vector quantity.

Given:-

• Object Distance (u) = 16 cm
• Size of image is four times the size of the object.
• Mirror used = Concave Mirror.

To Find:-

• Image distance from the mirror.

Solution:-

According to sign CONVENTION:-

• Object distance is always NEGATIVE.

Hence,

• Object distance (u) = -16

Now,

According to the magnification of a concave mirror,

• If the image FORMED is real then the magnification will be negative.

As stated in the question,

• Image formed is real and is four times the size of the object.

Hence,

• Magnification = -4

Now,

We know,

m =

Where,

• v = image distance
• u = object distance
• m = magnification

Now,

Putting all the values in the formula of magnification:-

= -4 =

= -4 =

= -4 × 16 = v

=> v = -64 cm

∴ The distance of the image from the mirror is 64 cm.

• h' = height of image
• h = height of object

Some other points:-

• If the magnification of the mirror COME negative then the image of the object formed is always real and inverted.

• If the magnification of the mirror comes positive then the image of the object formed is always virtual and erect.

Note:- This is applicable for both Concave and Convex mirror.

उपसहसंयोजक यौगिक' का और अधिक व्यापक परिभाषा यह है -

उपसहसंयोजक यौगिक वह है जिसमें कोई परमाणु अपने आक्सीकरण संख्या से भी अधिक संख्या वाली रासायनिक वस्तुओं (CHEMICAL species) से बन्धन बनाता है।

अनेकों प्रकार के उपसहसंयोजक यौगिक मौजूद हैं जिनमें जलीय विलयन में धातु (जल के अणुओं से उपसहसंयोजित) से लेकर विभिन्न जैवरासायनिक प्रक्रियाओं में भाग लेने वाले जटिल धात्विक एंजाइम आदि हैं।

उपसहसंयोजक बन्ध तब बनता है जब साझेदारी में जब एक ही तत्व द्वारा दोनों इलेक्ट्रान दिये जायँ। जो तत्व इलेक्ट्रान युग्म देता है वह दाता (DONOR) है और दूसरा वाला ग्राही (acceptor) है। इसे प्राय: तीर द्वारा ( --> ) प्रदर्शित किया जाता है। हाइड्रोजन पराक्साइड, सल्फर डाइआक्साइड, हाइड्रोनियम आयन, फेरोसायनाइड आदि इसके कुछ उदाहरण हैं।

Question:-

Find out the total resistance.

Note:-

• Its important to name all the resistance in order to MAKE it easier to find the resistance. (refer to the attachment provided)

Required SOLUTION:-

From the attachment we can clearly see, we have:-

• R₁ = 12.00 Ω
• R₂ = 5.00 Ω
• R₃ = 4.00 Ω
• R₄ = 8.00 Ω
• R₅ = 6.00 Ω

Also we can see that:-

• R₁ and R₅ are in parallel combination
• R₃ and R₄ are also in parallel combination.

We KNOW,

EFFECTIVE resistance in a parallel combination is calculated by the following formula:-

Hence,

For resistors R₁ and R₅ effective resistance is as FOLLOWS:-

=

=

=

=

=>

∴ Effective Resistance in the resistors R₁ and R₅ is 4Ω.

For resistors R₃ and R₄ effective resistance is as follows:-

=

=

=

=>

=>

∴ Effective Resistance in the resistors R₃ and R₄ is 2.7 Ω.

Now,

The resistors have come in series combination.

We know,

Effective resistance in a series combination is calculated by the following formula:-

Hence,

The effective resistance in resistors is as follows:-

= 4 + 5 + 2.7

=> = 11.7 Ω

Therefore, The total resistance across a and b is 11.7 Ω.

BASIC Differences. Although both instruments magnify objects so that the human eye can see them, a microscope looks at things very near, while telescopes view things very far AWAY.

Explanation:

Similarly telescope cannot function as microscope because a telescope make far away objects appear larger. If you TURN one around the EFFECT is reversed so that objects appear much smaller. That's not of much use.

MOMENTUM ::

→ Momentum of a BODY is the product of its mass and velocity.  

→ It is a vector quantity  

→ It has same direction as that of velocity.  

→ Mathematically momentum is given as P = mv

~Where,

• p is momentum of a body  
• m is mass of that body  
• v is velocity of that body

→ Law of CONSERVATION of momentum states that the total momentum of a body is directly proportional to a system of particles remains CONSTANT unless some external force acts on it.

_____________

IMPULSE ::

→ Impulse is the product of force and time for which it is applied.  

→ It is also a vector quantity  

→ It is represented by the symbol J ( capital )  

           J = F × t

~Where,

• F is the force applied  

• t is the time interval throughout which force is applied

To FIND:-

• The TOTAL EFFECTIVE resistance in the diagram provided.

Note:-

• It's NECESSARY to the label each resistor in a circuit. (As shown in the attachment)

Solution:-

From the attachment we have:-

• R₁ = 2Ω
• R₂ = 5Ω
• R₃ = 20Ω
• R₄ = 1Ω
• R₅ = 3Ω
• R₆ = 4Ω
• R₇ = 6Ω
• R₈ = 12Ω

Now,

Here we can see that:-

• Resistors R₂ and R₃ are parallel
• Resistors R₆, R₇ and R₈ are also parallel

Hence, Firstly let us find the effective resistance in the resistors connected in parallel combination.

We know,

Effective resistance in a circuit is represented as follows:-

For resistors R₂ and R₃:-

=>

=>

=>

=>

For resistors R₆, R₇ and R₈:-

=>

Now,

From the second attachment we can see that resistors R₁, R₅ and Rₜ are in series.

Also, resistors R₁ and Rₚ are in series.

We know,

Effective resistance in series combination is represented by:-

• Rₛ = R₁ + R₂ . . . . . . . . . . . . Rₙ

Hence,

For resistors R₄, R₅ and Rₜ:-

=

=

For resistors R₁ and Rₚ:-
