According to the consensus among those scientists who have studied the question, what is the scientific status of the notion that Earth is now or was in the past visited by extraterrestrial life?
 
  A) Although extraterrestrial life is theoretically plausible, and there is observational evidence for it, most scientists still will not accept the conclusion that we have been visited because it seems too unconventional or kooky.
  B) Extraterrestrial life is theoretically plausible, and there is real observational evidence for it, which is why most scientists believe that we have been visited.
  C) Although there is no real evidence that Earth has been visited by extraterrestrials, extraterrestrial life is theoretically plausible.
  D) Extraterrestrial life is implausible on general theoretical grounds, and there is no real evidence that Earth has been visited by extraterrestrials.
  E) Although extraterrestrial life is implausible on general theoretical grounds, there is observational evidence for it.

A proton is placed in an electric field of intensity 700 N/C. What are the magnitude and direction of the acceleration of this proton due to this field? (mproton = 1.67  10-27 kg, e = 1.60  10-19 C)
 
  A) 6.71  109 m/s2 opposite to the electric field
  B) 6.71  1010 m/s2 opposite to the electric field
  C) 6.71  1010 m/s2 in the direction of the electric field
  D) 67.1  1010 m/s2 opposite to the electric field
