Explain how machines can make work easier without violating the law of conservation of energy?
A simple machine will increase the total time effort must be exerted and decrease the amount of effort required in any given second.
The law of conservation of energy still holds because it still take the same amount of energy to get the job done.
A landspout is a type of tornado that forms when a rapidly rising air mass initiates a rotating updraft near the ground. Unlike traditional tornadoes that form from supercell thunderstorms, landspouts generally develop from non-supercell storms and are typically weaker in intensity. They are also usually shorter-lived and less destructive.
What does a divergent boundary look like?
A place where two plates slip past each other, moving in opposite directions
How many hours of sunlight in the winter are there?
The answer really depends on the season Iceland is in. There is no exact count for each season cause the days change. It is different from where people who for example live in Texas. During the winter some days it can be rare to see sunlight. In the summer it's the exact opposite. There could be 24 hours of sunlight one day. That commonly happens in Alaska as well.
What is meant by cyclone nisha?
Cyclone Nisha was a tropical cyclone that formed in the Arabian Sea in November 2008. It caused widespread damage in southern India and Sri Lanka, with heavy rainfall leading to flooding and landslides. Nisha weakened after making landfall and dissipated shortly thereafter.
What is the predominant wind direction for mangalore?
The predominant wind direction in Mangalore is from the southwest during the Southwest Monsoon season (June-September) and from the northeast during the Northeast Monsoon season (October-December).
Scientists generally divide the solar system into 5 major zones: the inner (or terrestrial) planet zone, the asteroid belt, the outer (or gas giant) planet zone, the kuiper belt, and the Oort Cloud. There is no exact boundary for these zones, however, and their sizes are not well determined; there is also overlap, in the sense that objects from one zone often appear in another zone.
Do surface waves or secondary waves cause the most damage in an earthquake?
Surface waves typically cause the most damage in an earthquake. These waves travel along the Earth's surface and have longer periods, resulting in strong shaking that can cause buildings and other structures to collapse. Secondary waves, on the other hand, are faster but typically cause less damage compared to surface waves.
How many layers does the earth have and what are they?
3 main layers, crust (lithosphere), mantle and core
^ although that is technically mostly correct, The Mantle is divided into 3 sections. the lithosphere is one of them.. and it includes the crust AND the tough top part of the mantle. The Lithosphere, which contains the tectonic plates (what causes pangea, continental drift, sea floor spreading, earthquakes, volcanoes, tsunamis, etc) 'floats' on top of the Asthenosphere which is the "middle" part of the mantle, and has a dense, 'plastic' kind of melted rock. The flow is very slow there, due to the density caused by the extreme pressure the 3rd one I'm not sure what its called. but i do know it includes the outer core as well extremely as the "bottom" mantel. then there is the inner core where is mostly hot metals at hot temperatures. oh wait i found out the last layer. In total there are 5 layers!!! look
READ THIS: "The structure of Earth can be defined in two ways: by mechanical properties such as rheology, or chemically. Mechanically, it can be divided into lithosphere, mesosphere-mantle, outer-core-1, and the inner-core. The interior of the earth is divided into 5 important layers. Chemically, Earth can be divided into the crust, upper mantle, lower mantle, outer core, and inner core.
What did Matthias Schliden do to contribute to the cell theory?
He studied plant structure under a microscope, and saw the intner cell parts. He found that the cell nucleus was very important, and thought that it might be connected with cell division. He concluded that all plant parts were made of cells, contributing to the cell theory.
Why does most of Russia's farming take place in Continental climate zone?
Most of Russia's farming takes place in the Continental climate zone because this region has a longer growing season, with warmer temperatures and more sunlight hours compared to other regions. These conditions are conducive to growing a variety of crops, including grains and vegetables. Additionally, the fertile soil and availability of water resources in the Continental zone further support agricultural activities.
Fog most frequently forms at night and disappears during the day why is that?
During the day, the sun warms the air near the ground, causing it to rise and mix with drier air above, which disperses the fog. At night, the ground cools, causing the air near the surface to cool and its moisture to condense into fog. This process is known as radiational cooling.
How does reproductive isolation increase diversity?
Reproductive isolation prevents gene flow between populations, leading to the accumulation of genetic differences over time. This can drive the divergence of populations into distinct species, increasing overall biodiversity. By maintaining distinct gene pools, reproductive isolation allows for new adaptations to arise and for evolution to proceed in different directions.
Examples of seed bearing plants?
Seed bearing plants make up the bulk of terrestrial plants, they are different from other forms of plants such as spore bearing plants (ferns).
Seed bearing plants are broken into two main divisions:
Anigosperms which have a seed protected within an ovary and
Gymnosperms which have seeds produced "naked" - these are mainly cone bearing plants.
Examples of Aniosperms include:
Petunia, Hibiscus, Oak, pea, tomato
Examples of Gymnosperms include:
Pine, Cupressus, Cycas and Cycad
How do some atoms in covalent bonds become slightly negative or slightly positive?
In a covalent bond, atoms share electrons. If one atom is more electronegative, it can pull the shared electrons closer to itself, giving it a slightly negative charge, while the other atom, with less electronegativity, can become slightly positive as the electrons are closer to the more electronegative atom. This creates a dipole moment in the molecule.
Cells break down food in a chemical reaction that releases energy what process is this?
This process is called cellular respiration. It involves the breakdown of food molecules such as glucose in the presence of oxygen to produce energy in the form of ATP, along with carbon dioxide and water as byproducts.
What happens if you add more loads to a series circuit?
When you have multiple loads in a series, the resistance of the loads is added together allowing very little current to flow through the circuit to power any of the loads, making for a low amperage circuit. If you have your loads in parellel, the resistance of the loads in the circuit is subtracted which allows more current to flow, making for a high amperage circuit.
Yes, geology can affect history by influencing the location of settlements, availability of resources, and natural disasters such as earthquakes or volcanic eruptions that can impact human societies. Understanding the geological features of an area can provide insights into past events and human activities.
Did Michael Faraday have any sisters or brothers?
Michael farady didnt have any siblings xx :} now go away xx
What country discovered sulfur?
Sulfur was discovered in ancient times by civilizations in present-day Iraq, Greece, and China. The earliest known occurrence of sulfur was in a Mesopotamian tablet dating back to 6th century BCE.
How did the development of early cities affect people's daily lives?
The development of early cities led to the formation of centralized governments, specialized professions, social stratification, and the establishment of trade networks. People's daily lives were impacted by increased urbanization, as they lived in closer proximity to each other and had access to new goods and services. This urban lifestyle also brought challenges such as overcrowding, sanitation issues, and social inequalities.
What is the most expensive document in the world?
a 710 year old copy of the magna carta was recently sold to a Washington businessman for 21.3 million dollars
Fahrenheit (symbol °F) is a temperature scale based on one proposed in 1724 by the German physicist Daniel Gabriel Fahrenheit (1686-1736), after whom the scale is named.
