effect of change in the normal activity of that which is being observed.
The most common frame of reference is the observer himself and, by extension, the room, lab, neighborhood, or environment in which he feels himself to be at rest.
They are: concave (curved away from the observer) convex (curved toward the observer)
A fan does not cool a room. It only cools moist objects in the room, so the method of cooling is evaporation.
Hey if you just asked this question in relation to "The Record Effect" then I think theyre talking about:"In physics, the term observer effect refers to changes that the act of observation will make on the phenomenon being observed."At least, that's what I just put on my homework. If you want to cite it its from Wikipedia
A. quiet.
The cast of The Changing Room - 1997 includes: Kate Champion as The Woman Meredith Kitchen as Observer 3 John Leathart as Observer 2 Bradley Terry as The Boy
Doppler's effect does not happen when the observer is moving towards the source because unlike the source when observer moves forward the waves are not compressed and they pass the observer without being compressed and since the doppler effect is due to the Change in wavelength of the wave, it fails to occur.

Zero. I am currently sitting in my chair in my room. If the plane is my chair and my room is the reference plane as long as I don't move my chair around the room it has no kinetic energy. Now if I expand my reference plane to an observer on the sun (I know) they are going to see me and my chair hauling butt at about 30km/s around the solar system along with my room my house and the rest of the planet this velocity and my mass mean there is kinetic energy.

An angle of declination is relevant when an observer is at a higher altitude than the object being observed. It is the angle made by the line of sight with the horizontal. Suppose this is angle x. Then if the altitude of the observer is known to be h, then line-of-sight distance to the object is h*sin(x). The object is h*tan(x) from the point below the observer at the level of the object.Conversely, if the line-of-sight distance from the object to the observer or the horizontal distance to the point directly below the observer is known, it is possible to calculate the height of the observer.
Absolute magnitude is based on an observer being at the same distance from any star.Apparent magnitude is based on the brightness of a star from Earth without any atmosphere.
an observer or a wide-angle rearview mirror
it means get in the game, to get modivated... to quit being a bystander or observer and start doing
Observer is a noun.
Because mass is observer dependent with it being tied to energy via E=mc^2 (and energy is certainly observer dependent). Rest mass however, IS the same for every observer. To be a little technical this is because the rest mass is a Casimir operator for the Lorentz group.
If the ball were simply dropped, the person dropping the ball and a stationary observer should see the same thing.
