Answer:

9658

Step-by-step explanation:

You can see the difference between divisor and remainder is 2

7-5=10-8=15-13=21-19=28-26===========2

LARGEST 4 digit number=9999

LCM of 7,10,15,21,28=420

9999=420×23+339

9999-339=9660

Means 9660 is largest 4 digit no that is completely divisible by GIVEN numbers .

But after subtracting 2 we get the REQUIRED n.

9660-2=9658

Hope you will like the answer.

What is a Mirror?

A mirror is a reflective surface that BOUNCES off light-producing either a real image or a virtual image. When an object is placed in front of a mirror, the image of the same object is seen in the mirror. The object is the SOURCE of the incident rays and the image is formed by the reflected rays. Based on the interaction of light, the IMAGES are classified as either a real image or a virtual image. A real image occurs when the light rays actually intersect while virtual images OCCUR due to the apparent divergence of light rays from a point.

Ray diagrams help us trace the path of the light for the person to view a point on the image of an object. Ray diagram uses lines with arrows to represent the incident ray and the reflected ray. It also helps us trace the direction in which the light travels.

<P>Answer:

p = 0 and q = -6

Step-by-step explanation:

We are given that -2 and 3 are ZEROES of x² + (p + 1)x + q

We know that :

Sum of zeroes = -B ÷ a. and Product of zeroes = c ÷ a

Hence

p + 1 = -2 + 3. q = -2 × 3

p + 1 = 1 q = -6

p = 0

Hope this helps....

Answer:

Theoretically, the same DC machine can be used as a motor or generator. Therefore, construction of a DC motor is same as that of a DC generator.

Working Principle Of A DC Motor

An electric motor is an electrical machine which converts electrical energy into mechanical energy. The basic working principle of a DC motor is: "whenever a current carrying conductor is placed in a magnetic field, it experiences a mechanical force". The direction of this force is given by FLEMING's left-hand rule and its MAGNITUDE is given by F = BIL. Where, B = magnetic flux DENSITY, I = current and L = length of the conductor within the magnetic field.

Fleming's left hand rule: If we stretch the first finger, second finger and thumb of our left hand to be perpendicular to each other, and the direction of magnetic field is represented by the first finger, direction of the current is represented by the second finger, then the thumb represents direction of the force experienced by the current carrying conductor.Above animation helps in understanding the working principle of a DC motor. When armature windings are connected to a DC supply, an electric current sets up in the winding. Magnetic field may be provided by field winding (electromagnetism) or by using permanent magnets. In this case, current carrying armature conductors experience a force due to the magnetic field, according to the principle stated above.

Commutator is made segmented to achieve unidirectional torque. Otherwise, the direction of force would have REVERSED every time when the direction of movement of conductor is reversed in the magnetic field. This is how a DC motor works!

Back EMF

According to fundamental laws of nature, no energy conversion is possible until there is something to oppose the conversion. In case of generators this opposition is provided by magnetic DRAG, but in case of dc motors there is back emf.

When the armature of a motor is rotating, the conductors are also cutting the magnetic flux lines and hence according to the Faraday's law of electromagnetic induction, an emf induces in the armature conductors. The direction of this induced emf is such that it opposes the armature current (Ia). The circuit diagram below illustrates the direction of the back emf and armature current. Magnitude of the Back emf can be given by emf equation of a DC generator.

Given Quadratic EXPRESSION 3x² - 4x + 7

compare this with ax² + bx + c , we get

a = 3 , b = -4 , c = 7

i ) Sum of the zeroes = - b/a

= - ( -4 )/3

= 4/3

ii ) PRODUCT of the zeroes = c/a

= 7/3

Answer :

1/α + 1/ß = -b/c

NOTE:

★ The possible VALUES of the variable which satisfy the EQUATION are called its roots or solutions .

★ A quadratic equation can have atmost two roots .

★ The general form of a quadratic equation is given as ; ax² + BX + c = 0

★ If α and ß are the roots of the quadratic equation ax² + bx + c = 0 , then ;

• Sum of roots , (α + ß) = -b/a

• Product of roots , (αß) = c/a

Solution :

Here ,

The given quadratic equation is :

ax² + bx + c = 0 .

Also ,

It is given that , α and ß are the roots of the given quadratic equation .

Thus ,

The sum of roots will be given as ;

α + ß = -b/a

Also ,

The product of roots will be given as ;

α•ß = c/a

Now ,

=> 1/α + 1/ß = (ß + α)/α•ß

=> 1/α + 1/ß = (α + ß)/α•ß

=> 1/α + 1/ß = (-b/a) / (c/a)

=> 1/α + 1/ß = (-b/a) × (a/c)

=> 1/α + 1/ß = -b/c

Hence ,

1/α + 1/ß = -b/c

Indira Gandhi in INDIA is known as the ‘Iron lady of India’. After the Lal Bahadur Shastri died, Indira Gandhi became the prime MINISTER if India.
