What happends every minute on earth?
Every minute on Earth, tens of thousands of lightning strikes occur, millions of people exhale carbon dioxide, and billions of heartbeats happen. Time zones change, satellites orbit the planet, and animals hunt, feed, and rest.
Will a light wave refract if it enters a new medium perpendicular to the surface Explain?
No, a light wave will not refract if it enters a new medium perpendicular to the surface. This is because refraction occurs when light enters a new medium at an angle, causing it to change speed and direction. When light enters perpendicular to the surface, there is no change in speed or direction, so refraction does not occur.
How frequently do high and low tides occur in most locations on Earth?
High and low tides typically occur twice a day in most locations on Earth.
How often, in most locations on earth, do high and low tides occur?
High and low tides typically occur twice a day in most locations on Earth.
How many refractions occur as a light ray travles through a lens?
Two refractions occur as a light ray travels through a lens: one as the ray enters the lens, and one as the ray exits the lens.
Why does an eclipse of the moon occur?
It happens when the Moon enters Earth's shadow.
What courses the seasons on earth?
the revolution of earth and the solstices that occur every once a...... don't know!!
Why do meteor showers occur only once every few years why not twice?
As comets orbit the sun, they leave a trail of debris behind them, tracing out their orbit. If the earth's orbit intersects the comet's orbit, some of that debris enters the earth's atmosphere and 'burns up' to give a meteor shower. Meteor showers therefore occur around the same time every year (e.g., the Perseids in August, or the Leonids in December), as the earth reaches the same point in its orbit around the sun (i.e., the point where it intersects the meteoroid stream). They don't occur "once every few years" (and i don't understand what you mean by "why not twice?" - why not what?)
What causes a sonic boom when a space shuttle lands?
Sonic booms occur when an object (space shuttle) is traveling faster than the speed of sound and the air in front of the object is compressed. As the air is compressed it emits a noise, thus the sonic boom.
What is the meaning of the expression 'window' in the context of a space shuttle landing?
'Window', when referring to a shuttle landing, refers to the period of time when a de-orbit burn can occur to enable the shuttle to land at one of the preferred landing sites (Kennedy Space Center is first, and Edwards Airforce Base if conditions are unsuitable at KSC). Usually there are only about three windows on a particular day on which the burn can occur. Should these be missed on each of the suitable orbits, the window for that day will be past, and more windows not available until the next day due to the earth's rotation and the shuttle's path around the earth.
Why are there two sonic booms when the space shuttle lands?
From NOVA: Because the Space Shuttle is so large (122 ft long), you will hear the sonic booms created by both the nose and tail shock waves (they occur about one-half second apart). All supersonic airplanes produce two sonic booms, but because they happen so close to each other, you hear them as one sound.
When do new moons and full moons occur?
New moons occur when the moon is directly between the Earth and the Sun, so it appears dark in the sky. Full moons occur when the Earth is between the Sun and the Moon, causing the entire sunlit side of the moon to be visible from Earth. New moons and full moons happen about every 29.5 days.
What is the longitude of all deserts?
There are deserts on every continent on earth and all occur at different longitudes.
Do winter occur in Jerusalem?
Yes, every single place on earth has a winter including Jerusalem
How does weightlessness occur in a space shuttle that is orbiting earth?
Weightlessness is a measure of how much resistance there is between an object and the local gravity. If you are standing on the ground, then there is 100% resistance between you and the pull of gravity. Your weight is equal to the pull of gravity on your mass. When you jump off a tall object, you are falling. You feel weightless because there is no resistance between you and the pull of gravity. When you are in a shuttle orbiting the Earth, both you and the Shuttle are falling in such a way that you never hit the ground. This is called an orbit. You feel weightless because you are falling. You just never hit the bottom like you would on Earth.
Where plasma is present in the universe?
Plasma can occur anywhere where there is extreme heat, plasma is not a substance but the fourth state after solid, liquid and gas. It is effect superheated gas, an example is the glow on the nose of the shuttle as it re-enters the atmosphere, another is the surface of the sun.
Why doesn't a solar eclipse occur every time the moon enters its new moon phase?
Because the orbit of the moon is tilted at an angle of 5 degrees to the ecliptic.
