It is normally said that mass and weight are the same on earth, but that is not true. In a vacuum on earth an object's mass would be the same as its weight, but air provides some buoyancy that lessens the weight, similar to what happens when something is weighed under water. If a person weighs 150 pounds, what would he weigh without the effect of the air? Does it make a significant difference?

1.The units for acceleration are m2/s2.
2.Acceleration is a change in speed over time.
3.The slope of a speed-time graph gives the velocity.
4.A positive slope on a distance-time graph means that the object is accelerating.

from your cellphones to your television to your satellite, they all have 1 thing in common that is they run on the spectrum band but in different frequencies...

so i want to know which is the most dangerous that can cause radiation?recently there is a article post on yahoo says that cellphones are safe....

can any one explain what is the cause of radiation from the frequency?example like higher frequency means more dangerous since satellite is using the higher band and is much stronger, so my final question is will any of the frequency in the spectrum band harm us? which of them would harm us more?
