You should be able to access your user's menu from one of the buttons on the TV itself.
If there is a BIOS password or an automatic brightness program active in the BIOS then your brightness keys may not work.
-- If the bulbs are in parallel, then the addition of a bulb has no effect on the brightness of those that were there before. -- If the bulbs are in series, then the addition of a bulb causes the brightness of those that were there before to decrease. (And I wasn't even there when you did the experiment !)
Yes any Panasonic tv is good. Don't get an lcd only get a plasma, reason why is because when you are looking at an lcd from an angle it gets grey the more of an angle you look at it. Plasma you can see a full 180 degrees without it turning grey. Also get the tv calibrated, what it does it sets the colors brightness and all the settings on it to where it will last up to 35 years or more.
its because astronomers basis of brightness is the sun...
The Panasonic is an excellent remote for someone who is challenged technically! A Panasonic remote would be an excellent remote to use, because it is very easy to setup the remote to a television.
The brightness of the bulb would decrease as the alligator clip moved along the pencil lead. This is because the resistance in the circuit would increase as the clip moves farther from the battery source, resulting in less current flow and therefore less brightness in the bulb.
The lights flicker when an appliance turns on because the sudden increase in power demand causes a temporary drop in voltage in the electrical system, affecting the brightness of the lights.
If the brightness is 'B' right now, when the object is at a distance 'D' from your eye, then-- If the object moves closer, to only [ 1/2 D ] from you, the brightness increases to [ 4 B ].-- If the object moves farther away, to [ 2 D ] from you, the brightnesses decreases to [ 1/4 B ].
I would go with the nikon, because the Panasonic will not give you the better focus and the make sure the ISO is high to get a better quality photo.
Adding more batteries to a circuit with light bulbs will increase the brightness of the bulbs. This is because the additional batteries will provide more voltage, which allows for a higher current to flow through the circuit. As a result, the bulbs will emit more light due to the increased energy supplied.
EASY: Because the TV is broken.
The relationship between brightness and perception in lighting, measured in lumens, demonstrates a logarithmic scale because our perception of brightness increases more slowly as the actual brightness increases. This means that doubling the lumens doesn't result in a perceived doubling of brightness.
