2.Why did people initially believe that a horse named "Clever Hans" could do math and that a procedure called "facilitated communication" could enable autistic children to type out complex messages?

A.In both cases, the unusual behavior was initially demonstrated under carefully controlled conditions

B.In both cases, scientists falsified their data

C.In both cases, people initially failed to recognize alternative explanations for the observed behavior

D.Both cases were very elaborate hoaxes designed by con artists who were intentionally trying to fool people

step-by-step explanation:

we can use this expression to calculate the energy gain as a particle moves with a field or the energy loss as it moves against it. (note that it is also used to define the electron-volt, a unit of energy equal to that gained by an electron as it falls through a pd of 1 v, i.e. w = 1 ev = 1.6 10-19 c 1 v = 1.6 10-19j).in fact this expression is really nothing more than the statement that potential is the potential energy per unit charge. in this case, v= w/qis simply stating that the change in potential energy(or work done) per unit charge is equal to the change in potential (or potential difference), v.student questions: uniform electric fields2electron beamcathode+5 kvanode0 v
