Laika | Fact Of The Day | First animal to make an orbital spaceflight around the Earth | TCS - The CBSE Solver

Fact Of The Day

The first animal to make an orbital spaceflight around the Earth was the dog Laika, aboard the Soviet spacecraft Sputnik 2 on 3 November 1957. Laika, was found as a stray wandering the streets of Moscow. Soviet scientists assumed that such animals had already learned to endure conditions of extreme cold and hunger . In 2008, nearly 50 years after the historic flight, a monument to Laika was finally installed outside Star City, a military facility in Russia where she was trained for her trip. The statue resembles a rocket that merges into a hand, launching Laika into space.

History Notes - The Rise of Hitler thecbsesolver BIRTH OF WEIMAR REPUBLIC • The defeat of imperial Germany in the war gave an opportunity to Parliamentary parties to reshape German political system. • National assembly met at Weimar and established a democratic constitution with a federal structure. • Deputies were now elected to the German Parliament or Reichstag on the basis of equal and universal votes cast by all adults including women. PROBLEMS WITH THE WEIMAR REPUBLIC • It was not received well by its own people largely because of the terms it was forced to accept after Germany's defeat at the end of the first world war. • The peace Treaty atVersailles with the allies was a harsh and humiliating peace. • Germany lost its Overseas colonies a tenth of its population 13% of its territories 75% of its iron and 26% of its Kol to France wall and Denmark and Lithuania. • Germany was held responsible for the war

Earthquake | Why earthquake happens | Why are earthquakes so hard to predict? | TCS - The CBSE Solver

Early Story:- In 132 CE, Chinese polymath Zhang Heng presented the Han court with his latest invention. This large vase, he claimed, could tell them whenever an earthquake occurred in their kingdom– including the direction they should send aid. The court was somewhat skeptical, especially when the device triggered on a seemingly quiet afternoon. But when messengers came for help days later, their doubts turned to gratitude. Today, we no longer rely on pots to identify seismic events, but earthquakes still offer a unique challenge to those trying to track them. So why are earthquakes so hard to anticipate, and how could we get better at predicting them? Earth’s structure: To answer that, we need to understand some theories behind how earthquakes occur. Earth’s crust is made from several vast, jagged slabs of rock called tectonic plates , each riding on a hot, partially molten layer of Earth’s mantle . This causes the plates to spread very slowly, at anywhere from 1 to 20 c

Stones Formation in Kidneys & treatment of kidney stones | Kidney Stones

The biggest kidney stone on record weighed more than a kilogram and was 17 centimeters in diameter. The patient didn't actually swallow a stone the size of a coconut. Kidney stones form inside the body, but unfortunately, they're extremely painful to get out. Stones Formation in Kidneys- A kidney stone is a hard mass of crystals that can form in the kidneys, ureters, bladder, or urethra . Urine contains compounds that consist of calcium, sodium, potassium, oxalate, uric acid, and phosphate . If the levels of these particles get too high, or if urine becomes too acidic or basic, the particles can clump together and crystallize. Unless the problem is addressed, the crystals will gradually grow over a few weeks, months, or even years, forming a detectable stone. Calcium oxalate is the most common type of crystal to form this way, and accounts for about 80% of kidney stones . Less common kidney stones are made of calcium phosphate , or uric acid . A slightly different t

Fats | Olive oil is good for you, and pancake mix is not. Why is that? | Which fat is good by CBSESolver | TCS

Olive oil is 100% fat; there's nothing else in it. Pancake mix, on the other hand, is only about 11% fat. And, yet, olive oil is good for you, and pancake mix is not. Why is that? As it turns out, the amount of fat we eat doesn't impact our weight or our cholesterol or our risk of heart disease s as well as kidney diseases nearly as much as what kind of fat we eat. But let's back up: Olive oil is 100% fat. Pancake mix is only 11% fat. But olive oil is mostly unsaturated fat, and it has no trans fat at all. On the other hand, more than half the fat in pancake mix is either saturated or trans fat. And, so, even though olive oil has 10 times as much fat as pancake mix, it's healthy for you, whereas pancake mix is not. Now, I'm not trying to pick on pancake mix. There are lots of foods with this type of fat profile. The point is this: It's not how much fat you eat, it's what kind of fat. And what makes a particular fat healthy or unhealthy is its shape. To

Why do some people get Bald? | Why Hair fall occurs | Why mostly men suffer Baldness

What do Charles Darwin, Michael Jordan, and Yoda have in common? They, like many other historical and fictive individuals, are bald , in some cases by their own choice. For centuries, a shining dome has been a symbol of intelligence, but despite this, many balding people still wish their hair would return. Scientists have long pondered, "Why do some people lose their hair, and how can we bring it back?" Science behind Baldness- The full-headed among us have about 100,000 to 150,000 hairs on our scalps, and scientists have discovered two things about this dense thicket. Firstly , the sprouting hair we see is mostly made up of keratin , the protein leftover from dead cells that are forced upwards as new cells grow beneath them. Secondly , the structures that drive hair growth are called hair follicles , a network of complex organs that forms before we're born, and grows hair in an everlasting cycle. This cycle has three main phases. The first is anagen ,

Motion | A scooterist covers a distance of 3 kilometres in 5 minutes. Calculate his speed in:

Class 9 Motion Physics 1. A scooterist covers a distance of 3 kilometres in 5 minutes. Calculate his speed in: (a) centimetres per second (cm/s) (b) metres per second (m/s) (c) kilometres per hour (km/h) Solution. (a) In order to calculate the speed in centimetres per second we should convert the given distance of 3 kilometres into centimetres and the given time of 5 minutes into seconds. Please note that 1 kilometre has 1000 metres and 1 metre has 100 centimetres. Now, Distance travelled =3 km = 3 x 1000 m = 3 x 1000 x100 cm = 300,000 cm ----------------- (1) Time taken = 5 minutes = 5 x 60 seconds = 300 s ------------------------------ (2) We know that, Speed = Distance travelled / Time taken = 300,000 cm / 300 s = 1000 cm/s --------------- (3) Thus, the speed of scooterist is 1000 centimetres per second. (b) In order to express the speed in metres per second we should convert the given distance of 3 kilometres into metres and the
