downGRAding preSCRIbing FUNCtional inTERnal Downtrodden has its stress on the first syllable. However, Option A (Downgrading) can also have its stress on the first syllable according to the Oxford Dictionary making Option C the safest option.

stressed syllables are the syllables within a word that have the most emphasis when spoken. for example: other - the syllable "oth" is stressed and the syllable "er" is not because "er" is pronounced less that "oth" the "er" tends to sound as if it were falling away at the end of the word. compound words; tend to be double stressed because both syllables are pronounced equally for example childhood- both "child" and "hood" are pronounced fully you can tell which syllable is stressed by saying the word naturally In words of two syllables or more, at least one of the syllables is usually pronounced with extra emphasis. We can divide syllables into stressed and unstressed categories. impound; (words with prefix are usually stressed on the second syllable) this would be stressed as imPOUND subject(verb); as a verb is stressed thus subJECT canoe; is stressed on the second syllable as caNOE knowledge; is a compound word made up of two different words ''know and ledge''. it is therefore stressed on the first syllable as KNOWledge

Emphatic stress is the placement of greater stress on a particular word or phrase in an utterance for the sake of emphasis or clarification. For questions on emphatic stress, the goal is to look for the question that contradicts the stressed word or phrase in the utterance. The utterance, in this context, is trying to clarify that the mother "can" actually cook the meal. So, it should be the response to the question "Isn't your mother able to cook the meal?"

Emphatic stress is the placement of greater stress on a particular word or phrase in an utterance for the sake of emphasis or clarification. For questions on emphatic stress, the goal is to look for the question that contradicts the stressed word or phrase in the utterance. "Eagles" is stressed in the utterance because it is the answer to the question: "Who won the Eagles?"

Marching soldiers crossing a suspension bridge are usually advised to break their steps to avoid damaging the bridge owing to resonance. The steps of the marching soldiers can set the bridge into vibration, and when the frequency of the bridge is equal to that of the steps of the soldiers, the resonance occurs,and at this resonance, the bridge vibrates violently with maximum amplitude, and can collapse.

for a body projected at an angle \theta to the horizontal, the time of the flight is given by T = (2u sin \theta)/g =(2x 40)x sin (30)/10 =(2 x 40) x (0.5)/10 = 4.0secs.

In a purely capacity circuit, voltage lags behind current by 90°, or current leads voltage by 90°

Since 1/32, is the fraction left of any radioactive material after 5half lives, that is: 1/32= (1/2)5. Thus if a half life is 50 days, 5 half lives will be 50 x 5= 250 days

The force acting on a moving charge in the magnetic field is given by: F= qVBSin \theta sin \theta =F=(8.0x10)-14/1.6x10-19x1.0x106x1.0 = (8.0x10)14/16 x 1013 (8.0x 10)-14/16x10-14 =0.5000 ∴ \theta= sin-1 0.5000 =30^\circ

When impurities are added to semi conductor , the semi conductor is said to be doped, and increases the conductivity of the semi-conductor.

The characteristics of a shadow are dependent on the intensity of the light source. A hard light will produce a shadow with a sharp edge, a soft light will produce a shadow with a more blurry edge.

for a real image 3 times the size of the object, it implies that the magnification 3 = v/u, 3 = 24/u, therefore 3u = 24, u = 8cm thus we have from the relation:m = (f)/(u)-f; that 3 = (f)/(8) - f. therefore f = 3(8-f) f = 24 - 3f ∴4f = 24; f = 6cm OR: (1)/(u) + (1)/(v) = (1)/(f). (1)/(8) + (1)/(24) = (1)/(f) therefore (3+1)/(24) = (1)/(f) 4/24=1/f;therefore 4f = 24 f = 6cm

Displacement and torque are vector quantities with both magnitude and direction, while options A, B, and D consist of vector and scalar.

In a wheel and axle system of mechanic, the mechanical advantage is given by its ratio of the radius of the wheel R, to the radius of the axle r. that M.A = R/r
