Intonation

Intonation is defined as a time or melody. It may also be called rise or fall in the speech sound or pitch change.Types if intonation:There are mainly 3 types of intonation. They are:1. Rising intonation2. Falling intonation3. Mixed intonation1.Rising intonation:If our utterance (speech) ends with a high pitch, it marks intonation. The rising intonation can be used in the following Situations.i. Yes/No – questions:Is that your house?ii. Repeated wh – question:What? Who?iii. Statement used as question:Rita got married?iv. Polite request:Please,...

Electrical Engineering Aspect

 Series and Parallel Circuit:1. Series Circuit:A simple circuit or path of any complex circuit in which same current passes through all the elements in that path is called series circuit. The general circuit diagram of series circuit using resistors is as shown as follows. Series circuit have following features.- Same current passes through all the element.i.e. I1 = I2= …………………… = IN = I- Voltage divides in all the components. So, It is known...

Basic Trigonometry

Angle Measurement :1. 1 radian angle (1ͨ) = 90 degrees (90°)2. 1° = 60 minutes (60')3. 1' = 60 seconds (60")4. 1 right angle = 100 grades =100ᵍ5. 1ᵍ = 100'6. 180° = 200ᵍ = π radians1 radians = 57° (approx.)Trigonometric ratios:1. (i) tanθ = sinθ/cosθ, Cotθ = cosθ/sinθ(ii) sinθ.cosecθ = 1(iii) cosθ.secθ= 1(iv) tanθ.cotθ= 12. (i) sin²θ + cos²θ = 1(ii) sec²θ – tan²θ = 1(iii) cosec²θ – cot²θ  = 13. |sinθ| ≤ 1, |cosθ| ≤ 1, |cosecθ| ≥ 1, |secθ|...

Voice

Note: there are two voices in English (Active and Passive voice). In the active voice the door of the action is given important and in the passive voice the victim (object) is given prominence. The object which is acted upon gains significance and the doer recedes into the background. Passive forms of active in English : Simple Tense Subject + (is/am/are) + past pacticles. examples : He often writes to me. - I am often written to by him. He teases...

Molecular weight And Mole

- “The molecular weight of substance is the relative mass of 1 molecule of it compared with 1/12 of the mass of an atom of carbon 12 isotope.” Molecular weight can be calculated by summing up the atomic weights of its constituent atoms. Eg. molecular weight of H2SO4 is 2 × 1 + 1 × 32 + 4 × 16 = 98 - According to Berzelius Hypothesis, “Equal volumes of all gases under the same conditions of temperature and pressure contain same number of atoms.” - According...

Projectile Motion

1. Projectile Motion :   For vertical displacement, y = usinθ t - ½gt2……………… (i) For horizontal displacement, X = ucosθ t t = x/ucosθ …………………. (ii) From equation (i) and (ii) y = usinθ.x/ucosθ – ½g(x/ucosθ). y = x tanθ - g/(2u2cos2θ) is similar to y = ax + bx2 so the path of projectile is parabolic. 2. Time of flight (T) : T = 2usinθ/g Time of ascent and time of descent are same i.e. t = usinθ/g. 3. Maximum Height (H)...
