Rate constant of a reaction is nearly doubled with rise in temperature by 10º.

First order reaction. 

The answer is

Zero order

A reaction takes place due to collide of molecules. The chances for a large number of molecules or ions to collide simultaneously are less. Hence, the reactions of higher order are less

The answer is

16 minutes.

A reaction takes place due to collide of molecules. The chances for a large number
of molecules or ions to collide simultaneously are less. Hence, the reactions of
higher order are less.

Rate constant of a reaction is nearly doubled with rise in temperature by 10º.

Any distances measured on that side are positive. Distances measured on the other side are negative. f, the focal length, is positive for a concave mirror, and negative for a convex mirror. When the image distance is positive, the image is on the same side of the mirror as the object, and it is real and inverted

जब इसके सारे इनपुट को लॉजिक हाइ (1) दिया जाय तब इसका आउटपुट लॉजिक लो (0) होता है और अन्य संयोजन में इसका आउटपुट लॉजिक हाइ (1) होता है। इसके विशेषताओं के कारण इसे सार्वभौमिक तर्क द्वार (यूनिवर्सल लॉजिक गेट) भी कहा जाता है, जिससे अन्य लॉजिक गेटों का निर्माण बडी आसानी से किया जा सकता है।

Correct option is (d) 2 x 10⁸ m/s and 2.25 x 10⁸ m/s

1. Image on the retina is real and inverted.

2. Diminished in size.

Myopia is a defect in which a person can see nearly objects clearly but cannot see distant objects distinctly. It is also called near / short sightedness.
Concave lens is used to correct mopia.

1. Trophic level 1 has maximum number of organisms because it includes producers.

2. DDT is accumulated at Trophic level 4. It occupies the topmost place in the given food chain.

abs(), log(), pow(), random(), round(), sqrt()

m = 20 kg

 F = 5 N

t = 1 sec

A = \(\frac{F}{m}=\frac{5}{20}=\frac{1}{4}\) m/s²

t = 1 sec

now, work done = Fs.

S = ut + 1/2 ut²

S = 1.125 m

F = 5 x 1.125 = 5.625J

Lagging of magnetization or induction flux density ‘B’ behind the magnetising force ‘H’ is known as magnetic hysteresis.  

The direction of induced emf can be find out by the ‘Fleming’s right hand rule’, and ‘lenz’s law’

Fleming’s right-hand rule:Fleming’s right hand rule states that, if one extends the thumb, fore finger and middle finger of the right hand at right angle to each other in such a way that the thumb point in direction of motion of the conductor, the fore finger in the direction of flux (from north to south pole), then the middle finger is indicate the direction of the induced emf in the conductor. 

Lenz’s law:The lenz’s law states that, electro magnetically induced current always flows in such a way or direction that the action of magnetic field set up by induced current tends to opposes the root cause which produces it. 

Eddy currents are those which are produced or induced in the mass of metal whenever the metal are moved in magnetic field of the magnetic field is moved across the mass metal so as to link it. The direction of this eddy current is always in opposite direction to the cause to produce them as per lenz’s law. 

Eddy current can be calculated by following equation

We = k B_max² f² t² v watt.

Where k – Constant  

B_max – Maximum flux density 

f – frequency of magnetic reversal 

t – thickness of each lamination 

v – volume if the armature core or mass metal. 

Development of eddy current is made use in energy meters to provide controlling torque and also in form of automatic starters in moving coil measuring instruments.

(i) (b) Distress

Biosphere refers to that part of environment where life exists.

Correct option: c) Waxy

• Social pressures are brought about from people who make excessive demands on us. It is the stress that we generate in our minds and is an internal source of stress. 
• Social stress is induced externally and result from our interaction with people.

• Seek first to understand, then diagnose and prescribe 
• Face to Face Communication is most effective 
• Communication becomes complex as the number of people we are communicating with increases 
• Communication across cultures differs

• Improves mood 
• Boosts immune system 
• Promotes longevity 
• Leads to burst of physical strength, which is vital for goal achievement

Major pulses of India: 

Black gram, chickpea, moog, pigeon pea, peas.

• High blood Pressure
• Heart attack
• Headache
• Fatigue

• presence of biological aberration 
• person may carry a vulnerability 
• presence of pathogenic stressors

Correct option: c) Griddling

Correct option is D) bought

Four objectives of cooking are:

1. To make the food more palatable. 

2. It kills the bacteria and keeps the food sterile. 

3. It improves the eye appeal of the food. 

4. Cooked food can be stored for a longer time.

Correct option is D) had torn

Potassium containing fertilizers: 

Sulphate of potash (SOP) and MOP (Muriate of potash).

Nitrogen containing fertilizers: 

Urea, Calcium Ammonium Nitrate (CAN)

Correct option is D) tore down

Correct option is A) sold out of

Correct option is A) go around

A = \(\begin{bmatrix}1&2\\3&1\end{bmatrix}\) B = \(\begin{bmatrix}2&1\\3&2\end{bmatrix},\) C = \(\begin{bmatrix}1&2&3\\3&1&0\end{bmatrix}\) 

AB = \(\begin{bmatrix}8&5\\9&5\end{bmatrix}\)

(AB)C = \(\begin{bmatrix}23&21&24\\24&23&27\end{bmatrix}\) 

BC = \(\begin{bmatrix}5&5&6\\9&8&9\end{bmatrix}\)

A(BC) = \(\begin{bmatrix}23&21&24\\24&23&27\end{bmatrix}\)

Hence (AB) C = A(BC)

Hence verified.

Correct option is C) most of whom had studied hard

A ² =I 

A.A=I 

Post multiplying by A ⁻¹ both the sides 

A.(AA ⁻¹ )=I.A ⁻¹ 

AI=IA ⁻¹ 

Hence, A ⁻¹ =A

A = \(\begin{bmatrix}3&-2\\ \lambda&-2\end{bmatrix}\)

A² = \(\begin{bmatrix}3&-2\\ \lambda&-2\end{bmatrix}\) \(\begin{bmatrix}3&-2\\ \lambda&-2\end{bmatrix}\) = \(\begin{bmatrix}9-2\lambda&-2\\ \lambda&-2\lambda+4\end{bmatrix}\)

⇒ \(\begin{bmatrix}9-2\lambda&-2\\ \lambda&-2\lambda+4\end{bmatrix}\) = \(\begin{bmatrix}9-2\lambda&-2\\ \lambda&-2\lambda+4\end{bmatrix}\) 

\(\therefore\) -2\(\lambda\) = -2

⇒ \(\lambda=1\)

Correct option is C) all of whom became musicians
