The mass of an object that weights 7 N on earth would be 0.7142857...
Weight = Mass x acceleration of gravity ( = 9.8)
7/ 9.8 = 0.7142857...
If an object weights 450 N, then it weights 45.91 pounds.
Weight = mass x acceleration of gravity (= 9.8)
450/ 9.8 = 45.918367...
Answer:
The speed of molecules in an "ideal" gas is related to the temperature
Advanced work indicates that
1/2 m v^2 = 3/2 k T where v^2 here is the mean square speed
This is true for H2, He, O2, Hg etc. and m is the molecular mass and k the Boltzmann constant
5 × 12 = 60 I got 60mph I multiply and that's how I get 60
<span>A lens is a piece of glass or other transparent substance with curved sides for concentrating or dispersing light rays, used singly (as in a magnifying glass) or with other lenses (as in a telescope). A binoculars, an eye, and a camera all contains a lens. A mirror does not contain a lens.</span>
