The apparent movement of an object across a background when observed from two different places is called an?
parallex
Does the frequency change if the observer moves?
actually the frequency donot change but apparent change in frequency is observed by the observer...........(may be this help u)
In an experiment a snail was observed to have moved a distance of 0.5 meters in to hours what rate of movement was observed in this experiment?
0.5 m in 2 hours would be 1 m per hour.
Can photoelectric effect be observed for all metals under same condition of incident light?
no , it cannot be observed in same conditions of incident light because, the threshold energy will be different for different metals.so in that particular threshold energy only the photoelectric effect for that metal can be observed.....
What is the Doppler effect on sound?
The Doppler effect is a phenomenon observed whenever the source of waves is moving with respect to an observer. The Doppler effect can be described as the effect produced by a moving source of waves in which there is an apparent upward shift in frequency for the observer and the source are approaching and an apparent downward shift in frequency when the observer and the source is receding. The Doppler effect can be observed to occur with all types of waves - most notably water waves, sound waves, and light waves.

Parallax is the apparent movement of an object across a background when observed from two different places.

When does a planet is said to be in retrograde motion?
A planet is said to be in retrograde motion when its apparent motion - the motion as seen by us, against the background stars - is from east to west.Planets spend more time in prograde motion, from west to east. The apparent movement of Sun and Moon against the background stars is also from west to east. Not to be confused with the daily motion, due to Earth's rotation.
What are two different types of apparent motions observed on Earth today that would not exist if the Earth were to stop rotating?
Aurora Borealis. Toilets flushing in vortexes.
What is to arrive at a conclusion based on observed and background knowledge?
infer
How can we tell the distance to the closest stars?
It is usually calculated through the parallax. The apparent position of the star, against the background of stars much further away, is observed at two opposite points in the earth's orbit around the sun. The apparent angular shift is recorded. Then, knowing the distance between the two positions of the earth, and a bit of trigonometry, the distance to the star can be calculated. An apparent displacement of 1/3600 degree (or 1 second) is called a parsec, and is equal to 3.086*10^13 kilometres
What is difference between apparent and intrinsic solubility?
Apparent solubility represents the solubility one observed during the experiment while the intrinsic solubility meant to the real or true solubility.
Is Vega or Betelgeuse the brightest star?
Brightness is a function of a stars luminosity as observed from Earth. So our Sun is the brightest. Vega has an apparent magnitude of: 0.03 Betelgeuse has an apparent magnitude of 0.42 So, in apparent magnitude, Vega is brighter.
Both erosion and weathering can be observed by?
watching for movement in rocks.
How can erosion and weathering be observed?

When First May Day movement was observed in India?
1367
What was the purpose of brown repeating the experiment with pollen grain that had been preserved in achool for 11 months?
He observed the same movement. When the experiment was repeated with rock dust the same movement was observed.
