The answer is Data collected from many experiments could not be explained.
Explanation:
With pretty much every science theory, the theory can not change without valid experimentation by multiple professionals.
Quartzite is produced when grains of quartz in sandstone are welded together when the rock is subjected to high temperatures. Quartzite<span> or Quarzit is a hard, non-foliated metamorphic rock which was originally pure quartz sandstone. </span><span>It is formed when a quartz-rich sandstone is altered by the heat, pressure, </span>
Answer:
charge will be equal to
Explanation:
We have given mass of the particle m = 1.45 gram = 0.00145 kg
Acceleration due to gravity 
Electric field E = 700 N/C
Electric force will be equal to
, here q is charge and E is electric field
For particle to be stationary this force must be equal to force due to gravity , that is mg force
So qE = mg

So charge will be equal to
The answer is A. the fields lines never cross, if you bring another magnet near it, the lines work just compress
Answer:
The answer is 0.8 m
Explanation:
According the attached diagram, if we take the momentum in the point 0:

Where
mD = mass of Diane = 64.2 kg
mJ = mass of Jack = 93.6 kg
Replacing:
