An example is a ball BEARING balanced on the EDGE of a razor blade.

The mass of the earth is 6 × 10 raised to 24 kg . The distance between the earth and the sun is 1.5 ×10 raised to 11 m . If the gravitational force between the two is 3.5 ×10 raised to 22 n , what is the mass of the sun ?

Answer» F =G M*m /r^2
3.5*10^22 = 6.67*10^-11* 6*10^24*m/2.25*10^22
m = 3.5*2.25*10^44/6.67*6*10^11

Limewater turns milky when CO₂ is passed through it. Write scientific reasons.

Answer»

Lime water is actually Ca(OH)2 . When it reacts with CO2 insoluble CACO3 is formed which turns solution milky. When excess CO2 is added/more CO2 is added to it, CaCO3 reacts with water and CO2 to form Calcium bicarbonate which is soluble. That is why the solution becomes clear again.
The EQUATIONS are-
1) Ca(OH)2 + CO2 ------> CaCO3 + H2O
2) CaCO3 + CO2 + H2O ----> Ca(HCO3)2

Use the Whittaker method to classify bacteria, protozoa, fungi, algae, prokaryotic and eukaryotic

Answer»

Abstract
Robert Whittaker's five-kingdom system was a standard feature of biology textbooks during the last two DECADES of the TWENTIETH century. Even as its popularity BEGAN to wane at the end of the century, vestiges of Whittaker's thinking continued to be found in most textbook accounts of biodiversity. Whittaker's early thinking about kingdoms was strongly shaped by his ecological research, but later versions were also heavily influenced by concepts in cell biology. This historical episode provides insights into important intellectual, institutional, and social changes in biology after World War II. Consideration of the history of Whittaker's contributions to the classification of kingdoms also SHEDS light on the impact of Cold War politics on science education and educational REFORMS that continue to shape the presentation of biological topics in introductory textbooks today.

Why we need to sleep ??

Answer»

Hey mate

here is ur answer
Our bodies all REQUIRE long periods of sleep in order to restore and rejuvenate, to grow muscle, repair tissue, and SYNTHESIZE hormones.

more explanations
:::::::::::::::::::::::::: :::::::::::

we need sleep because We tend to think of sleep as a time when the mind and body shut down. But this is not the case; sleep is an active period in which a lot of IMPORTANT processing, restoration, and strengthening occurs. Exactly how this happens and why our bodies are programmed for such a long period of slumber is still somewhat of a MYSTERY. But scientists do understand some of sleep's critical functions, and the reasons we need it for optimal health and wellbeing.

One of the vital roles of sleep is to help us solidify and consolidate memories. As we go about our day, our brains take in an incredible amount of information
