Mass SPECTROMETRY (MS) is an analytical technique that is used to measure the mass-to-charge ratio of ions. The results are typically PRESENTED as a mass spectrum, a plot of INTENSITY as a FUNCTION of the mass-to-charge ratio. Mass spectrometry is used in many different fields and is applied to pure samples as WELL as complex mixtures.

ong>ANSWER:

Number of cycle per minute = 75

explanation

Power output Wnet = 10 KW

Temperature of hot reservoir = 1500 K

Temperature of cold reservoir = 300 K

solution

we know that Efficiency is EXPRESS as

n = 1 -   

here  Tk is Temperature of hot reservoir and To is Temperature of cold reservoir

so put here value in equation 1 we get

n = 1- 300  ÷ 1500

n = 0.8

and Rate of heat input will be

Rate of heat input Qin = 10 × No. of CYCLES per sec

Rate of heat input Qin  = 10 n

n = Wnet ÷ 10 n    

put here value

0.8 = 10 ÷  10 n

solve it we get

n = 1.25

so here Number of cycle per second is = 1.25

Number of cycle per minute will be = 1.25 × 60

Number of energy cycle per minute = 75

Burning of paper and log of wood.

Digestion of food.

Boiling an egg.

Chemical BATTERY usage.

Baking a cake.

Milk going sour.

Various METABOLIC reactions that take place in the cells.

ong>ANSWER:

Copper is comparatively less reactive but reacts with REAGENTS like OXYGEN and water in atmosphere in a slow TIME. Also carbon dioxide helps in the reaction. As it is a metal, it will start corroding

After some days, we will observe greenish layer on the surface of copper vessel due to the formation of copper carbonate. The required reaction is:

Copper when reacts with carbon dioxide, water and oxygen FORMS basic copper carbonate.

The basic carbonate is a green coloured substance formed due time. Another example is the statue of liberty in New York, USA.

ong>Answer:

When an AMOEBA collides with food, the pseudopods "SWEEP" the food from all sides and, thus, the food particle, together with a small amount of fluid, is inside the cytoplasm of amoeba (it is CALLED phagocytosis), forming DIGESTIVE VACUOLES, where the digestive enzymes penetrate from the endoplasm.

It INVOLVES inhalation and exhalation of gases. Internal respiration involves gas exchange between the blood and body CELLS. CELLULAR respiration involves the conversion of food to energy. Aerobic respiration is a cellular respiration that requires oxygen while anaerobic respiration does not.

I can't understand HANDWRITING

Some FIBRES are called as synthetic fibers because these are manmade fibers prepared by using chemicals. These are made of SMALL units that join together to form long chains. Some of the examples of synthetic fibres are nylon, rayon, ACRYLIC, polyester ETC.

Millions of people along the East Coast and in the Midwestern United States are under a heat watch this weekend as a MASSIVE heat wave bears down. This scorching July weekend follows what NOAA recently reported was the hottest June on record.

But before you reach for a plastic water bottle to keep hydrated, you might think twice about whether it too has been wilting under a hot sun.

“The hotter it gets, the more the stuff in plastic can MOVE into food or drinking water,” says Rolf Halden, director of the Center for Environmental Health Engineering at Arizona State University’s Biodesign Institute.

Most plastic items release a tiny amount of chemicals into the beverages or food they contain. As temperature and time increase, the chemical bonds in the plastic increasingly break down and chemicals are more likely to leach. ACCORDING to the FDA, the amounts of the chemicals are too minuscule to cause health problems, but scientists looking at the long-term effects of filling our lives with plastic say all those small doses could add up in a big...

The hemoglobin (HB) molecule is roughly spherical and comprises TWO pairs of dissimilar subunits (FIGURE 1). Each of the subunits is a folded polypeptide chain (the globin portion) with a heme group (derived from porphyrin) attached. At the center of each heme group is a single atom of iron in the ferrous (Fe2+) state.
