Why does the Earth spin faster at the equator than the poles?

a
Due to the temperature differences on Earth, the land/sea near the equator goes at a faster rate. The Earth spins faster there only during the summer months.
b
The Earth is much wider at the equator than at the poles. It must cover a larger distance in the same amount of time (24 hours).
c
Due to the tilt of the Earth on its axis, the equator gets more sunlight -- therefore making it spin faster.

Answers

Answer:

Specifically, Earth rotates faster at the Equator than it does at the poles. Earth is wider at the Equator, so to make a rotation in one 24-hour period, equatorial regions race nearly 1,600 kilometers (1,000 miles) per hour. Near the poles, Earth rotates at a sluggish 0.00008 kilometers (0.00005 miles) per hour.

In a solution of a carbonated beverage, what is the dissolved carbon dioxide?
A. the solvent
B. the solute
C. the precipitate
D.saturated

Answers

Answer is B. The Solute.

In aqueous solution, solvent is water and solute (in this example carbon dioxide CO₂) is a substance dissolved in water.
The amount of solute that can be dissolved in a solvent depends of chemical composition, temperature and pressure.
Solution has a uniform composition and is able to be separated by physical means.

Carbonated beverage contains dissolved carbon dioxide and water, out of which water is solvent and carbon dioxide is solute and other sweeteners are also solute.

What is solution?

Solution is a homogeneous mixture which contain two component that are solute and solvent . Solute is the amount of component which is in small amount whereas solvent is a component which is  in large amount

Example: If we take sugar solution then the amount of sugar is small that is solute whereas water is in large quantity which is solvent. It is not necessary that water will be always solvent or liquid will be solvent, solid  and gas can be the solvent too.

In a solution of a carbonated beverage, water is solvent and carbon dioxide gas is the solute as it is dissolved in water. Thus carbon dioxide is solute in carbonated beverage.

How does the existence of the Gulf Stream affect the climate of Europe and the North Eastern US?

Answers

Answer:

The strong current of warm water influences the climate of the east coast of Florida, keeping temperatures there warmer in the winter and cooler in the summer than the other southeastern states. Since the Gulf Stream also extends toward Europe, it warms western European countries as well.

The east coast of the United States is affected mainly by the Gulf Stream current, which brings warm water from the tropics into higher latitudes. The warm current flows north along the coast towards Maine, before veering northeast out toward England.
It affects weather in the U.S., too. By bringing so much warm water along the mid-Atlantic and southeastern states, it adds some warmth to the eastern coast of the U.S. The Gulf Stream also affects the paths of hurricanes, and their strength they intensify as they draw up the heat from the warm water.

Grim says, "It all goes to show, that you can't judge a book by its cover." Who is he talking about? O Maxwell Freak Iggy O Gram O Kenny Kane (Maxwell's father).2. What is going on when he says this? Where are they, who go hurt, etc?3 Explain what Grims means events that evoke strong emotions when they occur are sometimes associated with vivid, detailed, and compelling memories. many laypersons believe that heightened emotional arousal leads to the formation of durable, accurate memories of the event, as well as the details surrounding how the news was received. an important question concerns whether memories of events associated with high levels of emotional arousal are qualitatively different from memories for ordinary events, which can be difficult to remember unless the event was special. researchers have studied the relationship between the vividness of emotional memories and their accuracy. in study 1, participants memories of a famous political assassination attempt were assessed twice, one month and seven months after the event. many participants reports included details about where they were, what they were doing, who brought the news, how they and others felt, and what happened afterward. strong emotional reactions to the event were associated with detailed reports that were consistent over time. in study 2, participants described how they had heard about a disaster one day after it had occurred. they answered specific questions about key details. two-and-a-half years later, the memories of nearly half of those participants were reassessed. each participants second account was compared with his or her first account. consistency across the two reports was used as a measure of accuracy. although participants expressed confidence in the accuracy of their second accounts, there were many discrepancies. only three participants provided the same account on both occasions, and 25% were wrong about every key detail. half of the participants got one key detail right (for example, who told them), while getting all the others wrong. in addition to omission errors, such as failing to report something that was said, many of the errors were intrusions, such as a detail that was consistent with the situation but missing from the initial report. not all emotional memories involve learning about momentous, newsworthy events. in study 3, participants who viewed a sequence of slides involving a violent car accident remembered more central aspects of the event (for example, a car involved in the accident) and fewer peripheral details (for example, the street). adapted from e. a. kensinger, "remembering the details: effects of emotion." 2009 sage publications and the international society for research on emotion; u. neisser and n. harsch, "affect and accuracy in recall." 1996 cambridge university press. question the finding from study 3 regarding the differential effect of emotional arousal on memory for central and peripheral details is best explained by which mechanism? increasing emotional arousal: Digital Fruit is financed solely by common stock and has outstanding 37 million shares with a market price of $10 a share.
