Answer»

In the Standard Model of Particle Physics, there are two classes, Fermions and Bosons. Fermions are the general matter particles and Bosons are the force carriers or interaction particles.
Bosons generally follows the BOSE-Einstein characteristics and forms one of the seven states of matter called the Bose-Einstein Condensate, at absolute zero.

These particles had been brought into significance by an Indian theoretical physicist, Dr. SATYENDRA Nath Bose, with the MAGNIFICENT achiever theoretical physicist, Dr. Albert Einstein. For his honour, the particles were NAMED after him.

Bosons have integral spin, unlike fermions and responsible for particle interactions. The particles that belong to the boson class are photons, gluons, W, Z, Higgs (tensor) and Graviton (hypothetical).

Short essay on is science a blessing or curse

Answer»

SCIENCE is a real blessing to the mankind n i think there's no life without science...
Science is something LIKE a miracle n we ACTUALLY lead a satisfied life from that....
Earlier there were no much innovations in science and there was no awareness among the people even,hence they USED to suffer a lot e.g.,having improper communication n transportation..
Science has brought a drastic change in the world n the people are more aware now. They can communicate in a fraction of SECONDS,have good transportation facilities n many more.
Earlier people were utilizing turmeric n several medicinal plants for different purposes without actually having a basic knowledge on their benefits but now with the development of science most of the people are well aware of their benefits n use them even in this modern world,basically south indians decorate their homes with mango leaves during festivals n earlier they used to do that thinking that their all doors will be clear for the arrival of Goddess Laxmi,it was just a blind belief and there's a science behind that, so during festivities their houses will be filled with guests n if they decorate with mango leaves,they will be providing oxygen even after plucking, so that was something good for them, most of the lndians don't take non veg during the month of karthik(some weeks in the month of Oct.or Nov.) thinking that it will impress Lord Shiva, but the fact is that it's somewhat winter in those months n due to the earth's rotation in those weeks it will be difficult to digest if non veg is consumed. In this way different people take differently but science has a great influence on us...
I feel that if something has prons then it is sure ro have some cons THUS Science can sometimes be a curse e.g. we have mobiles, d computers n many other modern devices but they release some harmful radiations n it's really bad for our health, people like Osama Bin Laden take the advantage of science negatively n they just utilize it for destroying anything....
Hence anything may be fatal or beneficial all around depends on how people utilize them so make proper utilization of science n it will create some miracles....
HOPE IT HELPS...

How is ruminant stomach stomach different from human stomach??

Answer»

(1) Ruminants's Stomach is a FOUR chambered complex stomach comprising of Reticulum,Rumen,Omasum and Abomasum whereas
Human Stomach is simple, single chambered stomach.

(2) In Ruminant's stomach, there are ruminal microbes which break down the cellulose and transform it into fatty acids. These fatty acids are absorbed DIRECTLY through ruminal wall into blood stream and accounts for 60 to 80 % of energy needs of Ruminants.
In contrast, human stomach can not break down cellulose and derive no energy from it.

(3) The microbes of Ruminant's rumen,serve to manufacture protein from non proteinous substances like urea and convert them into AMINO Acids.
Human, in contrast, have to OBTAIN Amino Acids, directly through their diet.
These are the main difference between Ruminant's stomach and Human Stomach.
Hope it helps.

what will be the ratio of wave length of two ultrasonic waves having frequencies 10000hz and 1.5 *10^4 hz, if speed of both the waves is same

Answer»

1) ULTRA sonic SOUND property
wavelength = a (Lambada)
SPEED = V1
frequency = n1 = 10000Hz


2) ultra sonic sound property
wavelength = a1 (Lamba)
speed = V1
frequency = n2 = 1.5×10^4Hz = 15/10×10000 = 15000Hz

(V1/n1)/(V1/n2) = a/a1
V1/n1×n2/V1 = a/a1
n2/n1 = a/a1
15000/10000 = a/a1
15/10 = a/a1
3/2 = a/a1

so ratio of the wavelengths is = a : a2 = 3 : 2

how much a body of weight 35 n will weight in water, if it displace one litre of water ? (g= 9.8m sec ^-2)

Answer»

Weight of body = 35N
Body displaces one litre of water .
∵ Archimedes theory ,
weight of body in water = WEIGH of body in air - weight of water displaced by body

∵ 1 litre of water is displaced by body
∴ volume of water = 1 L
we know, density of water = 1000 KG/m³
Hence, MASS of water = 1L × 1000 kg/m³
= 10⁻³ × 1000 kg [ ∵ 1L = 10⁻³ m³ ]
= 1kg

Now, weight of body in water = 35N - 1kg × 9.8 m/s² [ ∵ weight = mass × g]
= 35 N - 9.8N = 25.2N

40.

a body of mass 5 kg intially at rest is subjected to a force of 20 n . how much kinetic energy is acquired by the body at the end of 10 sec

Answer»

Initial Velocity = u = 0
Time = 10 s
MASS= 5kg
Acceleration= a
Force = mass * acceleration = 20N

5 * a = 20
a = 4 m/s^2

Final velocity = V = u + a*t
= 0 + 4 * 10
= 40m/s

Final KE= 1/2 m*v*v = 1/2 * 5 * 40 * 40 = 4000J

a particle with charge of 10 coulomb is kept at rest in a strong magnetic field of 100000 tesla magnitude. the force experienced by charged particle is

Answer»

A CHARGED PARTICLE of 10C is kept at rest in magnetic FIELD of 100,000 Tesla magnitude. Means VELOCITY of charge particle , v = 0.

But we know, FORCE experienced by charged particle in magnetic field is given by
\bold{F=q(v\times B)}
Here v is velocity of particle and B is megnetic field .
if velocity of particle = 0 , then force experienced by charged particle in magnetic field = 0 .

Hence, force experienced by charged particle = 0 N

three bulbs of rating 40 w, 60 w, and 100w, are desinged to work on 220 v mains . which bulb will glow most bright if they are connected in series across 220v mains

Answer»

By applying the FORMULA, P=VI
 P ∝ I
i.e, more is the power, the more is the current.

Since,the 100 W bulb has the MAXIMUM power,it will have the maximum current and thus the 100 W bulb will GLOW most brightly.
