What man made objects are in the therospere?
The thermosphere is an atmospheric layer where man-made objects such as satellites and space stations orbit the Earth. These objects can be found at altitudes ranging from 80 km to 550 km above the Earth's surface.
What direction does longitude travel on the globe?
Longitude lines connect the North and South Poles and measure distances east or west of Greenwich.
Three ways that flowers attract animals to pollinate them?
Who invented the first planetary rover?
Soviet Union sent first rover to Moon in 1970, and first rover to Mars in 1971.Lunokhod(Soviet Union) is supposed to be the first rover, first rover NASA used was in 1996.
Why the cinema screen is concave position?
The concave shape of a cinema screen helps to direct light more efficiently towards the audience, creating a more immersive viewing experience. This shape also helps to maintain a uniform focus across the entire screen, reducing distortion and improving clarity for viewers.
What was the movement among the social and intellectual elite that emphasized science and reason?
The movement was called the Enlightenment. It encouraged the use of scientific methods and reasoning to understand and improve society, emphasizing individual freedom, equality, and progress. Key figures of the Enlightenment included Voltaire, John Locke, and Isaac Newton.
light is focused onto the retina, which is made up of light sensitive cells called rods and cones. THey detect this incident light energy and then convert it into signals, which are sent to the brain. In order to focus on near or far objects, the lens in our eyes is suspended my ciliary muscles. when we focus on something far away, they pull the lens flat as the light has more time to bend, do doesn't need to be bent as much. Therefore, with objects upclose, the muscles cause the lens to relax and become fatter, bending the light drastically to focus the image
Where did Alfred Wallace go to college?
Alfred Wallace did not attend college. He was largely self-taught through his own studies and fieldwork.
What is the structure of ethyl octanoate?
Ethyl octanoate has the chemical formula C10H20O2 and its structure consists of a linear carbon chain of eight carbons (octanoate) with an ethyl group (C2H5) attached to one end. It is an ester compound formed from the reaction between ethanol and octanoic acid.
A star is born from a cloud of gas and dust in space when the material collapses due to gravity, causing it to heat up and ignite nuclear fusion in its core. This fusion process generates energy and light, allowing the star to shine and continue to evolve throughout its lifespan.
What dark area made by an object blocks out light?
A shadow is a dark area created when an object blocks light from reaching a surface. Shadows are formed when an object obstructs the path of light, causing a shadow to appear on the opposite side of the light source.
This description fits creatures like snails or clams with shells that can be coiled or have two hinged pieces. However, the mention of capturing prey with tentacles suggests a sea creature like a jellyfish or anemone.
A nebula is a cloud of gas and dust in outer space. These formations can be the birthplaces of stars or remnants of dying stars. Nebulae are commonly observed by astronomers and can come in various shapes and sizes.
Why is there a compass rose on every map?
A compass rose on a map helps users determine direction by indicating cardinal (north, south, east, west) and often intermediate (northeast, northwest, southeast, southwest) directions. This aids navigation and orientation on the map, making it easier to understand geographical relationships and find one's way.
How does light travel in space without any medium?
Light is an electromagnetic wave that consists of tiny particles called photons this wave electrical origin and have the ability to travel through a vacuum as they do not require a material medium for propagation.So heat and light from the sun reach through a vacuum.If they required a medium they would never reach us across the empty space!!
How can blimps be use in scientific studies of the air?
Blimps can be used in scientific studies of the air to collect atmospheric data such as temperature, humidity, pressure, and air pollution levels at different altitudes. They can also be equipped with specialized sensors to study air composition, wind patterns, and weather patterns in a cost-effective and environmentally friendly manner. Additionally, blimps can provide a stable platform for researchers to conduct experiments or observations in the lower atmosphere.
Information about light and shadow?
Light is a form of electromagnetic radiation that allows us to see objects. Shadows are created when an opaque object blocks light, preventing it from reaching a certain area. The size and shape of a shadow depends on the angle and distance of the light source, as well as the position of the object casting the shadow.
To calculate her angular momentum, you would need to know her moment of inertia (which depends on both her mass and how this mass is distributed relative to the axis of rotation), her velocity (speed at which she travels in a circular path), and the radius of the circle she is skating. You would use the formula for angular momentum, which is given by the equation: L = I * ω, where L is angular momentum, I is moment of inertia, and ω is angular velocity.
Does a ball pen floats in space?
Everything, including ball point pens, floats in space because there is no gravity acting upon it.
Can spherical abberation be corrected by combination of lenses?
Spherical aberration can be minimized by several methods: Changing curvature of both surfaces of a lens allows sharp focus at a particular distance. Aspheric lenses - i.e. lenses with a special non-spherical profile, is another.
What are the three main elements that determine a stars brightness from earth?
The three main elements that determine a star's brightness from Earth are its luminosity (intrinsic brightness), distance from Earth, and any intervening dust or gas that may affect the amount of light that reaches Earth.
The scale of existence is vast and encompasses everything that we know of in the universe, from the smallest particles to the largest galaxies. It is difficult to quantify or measure the size of existence as it extends far beyond our current understanding.
because they flap and collect wind then they get to fly.
answer #2
a bird wing creates lift by bending and flexing and creating lift by shaping the wing so the air moves over the top faster than the bottom which lowers the pressure on the top and hence "lift". An airplane does the same thing but doesn't flex the wing as a bird does. They do change the shape using flaps and slats and changing the attack angle to the wind as in supersonic aircraft.
Yes, "Ra.One" is a science fiction film directed by Anubhav Sinha. It revolves around a game designer who creates an artificial intelligence villain that escapes into the real world.
How does cataract affects a persons ability to see well?
Cataracts cause clouding of the natural lens of the eye, leading to blurry or hazy vision. This can result in difficulty seeing clearly, both near and far, and may cause sensitivity to light and glare. As the cataract progresses, colors may also appear faded or yellowed.
