Polynomials

NCERT Solutions Ex 2.2

Q1: Find the zeroes of the following quadratic polynomials and verify the relationship between the zeroes and the coefficients.
(i)  x²-2x-8
(ii) 4s²-4s+1
(iii) 6x²-3-7x
(iv) 4u²+8u
(v) t²-15
(vi) 3x² - x -4

Answer: (i)  x²-2x-8 = (x - 4)(x +2)
⇒x²-2x-8 = 0 when x - 4= 0 or x + 2 = 0
∴ Zeroes of x²- 2x - 8 are 4 and -2.
Sum of zeroes =
Product of zeroes =
Hence relationship between zeroes and coefficients are verified.

(ii) 4s²-4s+1
= (2s -1 )²
⇒ 4s²-4s+1 = 0 when 2s -1 = 0
⇒ s = 1/2
∴ Zeroes of 4s²-4s+1 are ½ and ½.
Sum of zeroes =
Product of zeroes =
Hence relationship between zeroes and coefficients are verified.

(iii) 6x²-3-7x
= (3x + 1)(2x - 3)
⇒ 6x²-3-7x = 0 when 3x + 1 = 0 OR 2x - 3 = 0
⇒ x = -1/3 or x = 3/2 ∴ Zeroes of 6x²-3-7x are -1/3 and 3/2
Sum of zeroes =
Product of zeroes =
Hence relationship between zeroes and coefficients are verified.

(iv) 4u²+8u
= 4u(u + 2)
⇒ 4u²+8u = 0 when 4u = 0 OR u + 2 = 0
⇒ u = 0 OR u = -2
∴ Zeroes of 4u²+8u are 0 OR -2
Sum of zeroes =
Product of zeroes =

Hence relationship between zeroes and coefficients are verified.

(v) t²-15
= t² - 0t -15 = (t - √15)(t + √15)
⇒ The value of t²-15 is 0 when t - √15 = 0 OR t + √15 = 0
⇒ t = √15 or t = -√15.
Sum of zeroes = √15 -√15 = 0
Product of zeores = (√15) ☓ (-√15) = -15
Hence relationship between zeroes and coefficients are verified.

scientific management theory
credits: wiki

Q1: What is meant by Management principles?

Answer: Management principles are broad and general guidelines for decision making and behaviour. These are those basic truths which have the ability to predict the result of the managerial activities.

Q2: How are the principles developed?

Answer: These are developed on the basis of observation and experimentation as well as personal experiences of the managers.

Q3: Why is it said that the principles of management are universal?

Answer: Because these principles are intended to apply to all types of organisations, business as well as non-business, small as well large, public sector as well as private sector, manufacturing as well as the services sectors.

Q4: Why are the principles of management are considered contingent?

Answer: The application of principles of management is contingent or dependent upon the prevailing situation at a particular point of time. The
application of principles has to be changed as per requirements.

Q5: Why is it said that principles of management are flexible?

Answer: This is because they can be modified by the managers when the situation so demands.

Q6: The principles of management aren't rigid and can be modified when the situation demands. Which nature of principles is being discussed here?

Answer: Flexibility.

Q7: Which principles of management promotes team spirit?

Answer: Esprict De Corps.

Q8: State one violating effect of the principle of ‘Division of work’.

Answer: Lack of specialization.

Q9: Define scientific management.

Answer: It is the application of a scientific approach to managerial decision making.

Q10: Who was the first to identity functions of management?

Answer: Henri Payol

CBSE Class 12 - Physics - CH3 - Current Electricity (NCERT Solutions)

Current Electricity

NCERT Solution 

Q1: The storage battery of a car has an emf of 12 V. If the internal resistance of the battery is 0.4Ω, what is the maximum current that can be drawn from the battery?

Answer: Emf of the battery, E = 12 V
    Internal resistance of the battery, r = 0.4 Ω
    Maximum current drawn from the battery = I

   According to Ohm’s law,
          E = Ir
          I = E/r  = 12/0.4 = 30 A
   Thus, the maximum current drawn from the given battery is 30 A.


Q2: A battery of emf 10 V and internal resistance 3 Ω is connected to a resistor. If the current in the circuit is 0.5 A, what is the resistance of the resistor? What is the terminal voltage of the battery when the circuit is closed?

Answer: Given,
                Emf of the battery, E = 10 V
                Internal resistance of the battery, r = 3 Ω
                Current in the circuit, I = 0.5 A
                Resistance of the resistor = R
       Applying Ohm’s law,
                I = E/(R + r)
           R + r = E/I  = 10/0.5 = 20 Ω
           ∴ 20 - 3 = 17 Ω

       Terminal voltage of the resistor = V
       According to Ohm’s law,
                    V = IR = 0.5 × 17 = 8.5 V
       ∴ the resistance of the resistor is 17 Ω and the terminal voltage is 8.5 V.

Q3: a) Three resistors 1 Ω, 2 Ω, and 3 Ω are combined in series. What is the total resistance of the combination?
       b) If the combination is connected to a battery of emf 12 V and negligible internal resistance, obtain the potential drop across each resistor.

Answer:
    (a) Three resistors of resistances 1 Ω, 2 Ω, and 3 Ω are combined in series.
         Total resistance of the series combination is the algebraic sum of individual resistances.
         ⇒ Total resistance = 1 + 2 + 3 = 6 Ω
