The general form of Pythagorean triplets
Pythagorean triples are a2+b2 = c2 where a, b and c are the three positive integers. These triples are represented as (a,b,c). Here, a is the perpendicular, b is the base and c is the hypotenuse of the right-angled triangle.

An electromagnet is a type of magnet in which the magnetic field is produced by an electric current. Electromagnets usually consist of wire wound into a coil. A current through the wire creates a magnetic field which is concentrated in the hole, denoting the centre of the coil.

If a plant has fibrous roots, what type of venation are its leaves likely to have?
a n s w e r
<article id="post-1205991">Plants with fibrous roots have parallel venation in their leaves. For example, grass, wheat maize, etc. have fibrous roots with parallel venation.

Working of democracy in Pakistan :
(i) After Pakistan framed its first constitution, General Ayub Khan took over the administration of the country and soon got himself elected. He had to quit the office when there were agitations and dissatisfaction in his rule. This gave a way to the military to takeover the government of the country.
(ii) After 1971, an elected government was formed under the leadership of Zulfikar Ali Bhutto, which was removed by General Zia-ul-Haq in 1977.
(iii) Again in 1982, in Pakistan, by a pro-democracy protest, democratic government was established in 1988, under the leadership of Benazir Bhutto and Nawaz Sharif. Later on, history repeated and General Pervez Musharraf again took the command in 1999 and got elected in 2005.
(iv) It is, therefore, said that military rule and ‘ democracy are two sides of the coin in Pakistan.
Though Pakistan’s politics centered around the competition between People’s party and Muslim League, Several factors have contributed to Pakistan’s failure in building a stable democracy.

A food chain refers to the order of events in an ecosystem, where one living organism eats another organism, and later that organism is consumed by another larger organism. The flow of nutrients and energy from one organism to another at different trophic levels forms a food chain.
The food chain also explains the feeding pattern or relationship between living organisms. Trophic level refers to the sequential stages in a food chain, starting with producers at the bottom, followed by primary, secondary and tertiary consumers. Every level in a food chain is known as a trophic level.

After fertilisation has taken place in flower, a zygote is formed which divides several times to form an embryo within the ovule. The ovule develops a tough protective coat around itself and is gradually converted into a seed. The ovary grows rapidly and ripens to form a fruit. Meanwhile, the petals, sepals, stamens, style and stigma gets shriveled and fall off.

Let
X, be the initial length, and r
Y be the cross-sectional area
R be the resistance of wire.
Let X', Y' and R' be the new length, cross- sectional area and resistance of wire after the length of wire is increased.
Length is increased by 0.1%, therefore,
L' = L+(0.1/100)L
L' = 1.001 L
Since the volume of wire remains same, thus,
V' = V
A'*L' = A*L
A' * 1.001 L = A*L
A' = A/1.001
New Resistance,
R' = ρL'/A'
= ρ*1.001 L/(A/1.001)
= (1.001)²(ρL/A)
R' = 1.002*R
% change in resistance = (Final resistance - Initial resistance)/Initial resistance * 100%
= (R' - R)/R*100%
= (1.002R - R)/R*100%
= 0.002 * 100%
= 0.2%
Thus, resistance of wire is increased by 0.2%.

| Effusion | Diffusion |
| Effusion is said to occur when gas molecules escape through a pinhole into a vacuum. | During diffusion one gas mixes with another usually by thermal random motion resulting in the collision between each other while releasing molecular energy. |
| Effusion in simple terms is the ability of gas to travel through a small opening. | Diffusion is the ability of gases to mix with each other usually in the absence of a barrier. |
| Effusion occurs when the size or aperture of the hole is smaller than the mean free path of the molecules. | Diffusion happens when there are no holes or if holes in the barrier are larger than the mean free path. |
| During effusion particles move faster than diffusion because there is no collision between molecules. | Diffusion rate is limited by the size and kinetic energy of the other particles. |
| Effusion occurs or is facilitated by a difference of pressures. | Diffusion occurs due to difference in concentrations. |
