I want to say frequencies would be the answer. I could be wrong though. Hope this may have helped!
Sifting is the best method cuz all the dirt will be carried by wind.
Answer: At that moment, all the baseball's kinetic energy has been converted to potential energy.
Explanation: I took the test
True. That is how powerful the sun is. But it will explode in only about 5 billion years.
Answer:
d) 289.31 m
Explanation:
Energy provided by potential energy = mgh = m x 9.8x 200 sin10.5 = 357.18m
Energy used by friction = μmgcos 10.5 x 200 = .075 x m x 9.8 x cos 10.5 x200 = 144.54 m .
Energy used by friction on plain surface = μmg x d.( dis distance covered on plain ) =.075x m x 9.8 xd = .735 m d
To equate
357.18 m -144.54 m = .735 m d
d = 289.31 m .
