In the summer the land gets hotter, heating the atmosphere and pulling in cooler AIR from the oceans. In the winter the land cools off and winds move towards the warmer ocean. |

Eger type questions.The ratio of the lengths of two rods is 4:3. The ratio of their coefficients of cubical expansion is 2ratio3 Then the ratio of their linear expansion when they are heated through same temperature difference is x ratio 9.then x value |
|
Answer» the relation between cubical expansion coefficient and linear expansion coefficient is, \gamma = 3\alphaγ =3α Thus, \frac{{{\alpha _1}}}{{{\alpha _2}}} = \frac{{{\gamma _1}}}{{{\gamma _2}}}=\frac{2}{3} α 2α 1 = γ 2γ 1 = 32 The linear expansion is GIVEN as, \Delta l = \alpha l\Delta TΔl=αlΔT Therefore, \frac{{\Delta {l_1}}}{{\Delta {l_2}}} = \LEFT( {\frac{{{\alpha _1}}}{{{\alpha _2}}}} \right) \TIMES \frac{{{l_1}}}{{{l_2}}} Δl 2Δl 1=( α 2α 1 )× l 2l 1 = \frac{2}{3} \times \frac{4}{3} = \frac{8}{9}= 32× 34= 98 THIS IS YOUr ANSWER |

What are the consequences of the validation of our beliefs by science? |
|
Answer» Explanation: religious belief helps INDIVIDUALS to cope with stress and anxiety. But is this effect specific to supernatural beliefs, or is it a more GENERAL function of belief — including belief in SCIENCE? We DEVELOPED a measure of belief in science and conducted two experiments in which we manipulated stress and existential anxiety. In Experiment 1, we assessed rowers about to compete (high-stress condition) and rowers at a training session (low-stress condition). As predicted, rowers in the high-stress group reported greater belief in science. In Experiment 2, participants primed with mortality (vs. participants in a control condition) reported greater belief in science. In both experiments, belief in science was negatively correlated with religiosity. Thus, some secular individuals may use science as a form of “faith” that helps them to deal with stressful and anxiety-provoking situations. Keywords: Belief, Belief in science, Religious belief, Stress, Existential anxiety |

Answer» ACIDIC substances are usually identified by their sour taste. An acid is basically a molecule which can donate an H+ ion and can remain energetically favourable after a loss of H+. Acids are known to turn blue litmus red. Bases, on the other hand, are CHARACTERIZED by a bitter taste and a slippery texture. A base that can be dissolved in water is referred to as an alkali. When these substances chemically react with acids, they yield salts. Bases are known to turn red litmus blue. if U like it pls MARK this ans as BRAINLIEST |

An elevator carrying a maximum load of 1800 kg (elevator + passengers) is movingup with a constant speed of 2 ms^-1. The frictional force opposing the motion is4000 N. Determine the minimum power delivered by the motor to the elevator.(Take g = 10 m/s^2) |
|
Answer» Answer: 43280 Watt Explanation: elevator MOVES UPWARD HENCE frictional force OPPOSE their motion in downward. so, net force act on elevator =mg+F because mg is act downward and F (frictional force) act also downward. Fnet=(1800 x 9.8+4000) N =(17640+4000)N=21640N now power =Fnet x speed =21640 x 2=43280 watt |

How is a cell different from civilization |
|
Answer» Answer: Cells to Civilizations is the first unified account of how life transforms itself — from the production of bacteria to the emergence of complex civilizations. What are the connections between EVOLVING microbes, an egg that develops into an infant, and a child who learns to walk and talk? Award-winning scientist Enrico Coen synthesizes the growth of living SYSTEMS and creative processes, and he reveals that the four great life transformations — evolution, DEVELOPMENT, learning, and human culture — while TYPICALLY understood separately, actually all revolve around shared core principles and manifest the same fundamental recipe. Coen blends provocative discussion, the latest scientific research, and colorful examples to demonstrate the links between these critical stages in the history of life. Coen tells a story rich with genes, embryos, neurons, and fascinating discoveries. He examines the development of the zebra, the adaptations of seaweed, the cave paintings of Lascaux, and the formulations of Alan Turing. He explores how dogs make predictions, how weeds tell the time of day, and how our brains distinguish a Modigliani from a Rembrandt. Locating commonalities in important findings, Coen gives readers a deeper understanding of key transformations and provides a bold portrait for how science both frames and is framed by human culture. A compelling investigation into the relationships between our biological past and cultural progress, Cells to Civilizations presents a REMARKABLE story of living change. Explanation: |
