Explanation / Answer

1) As a probe nears the black hole, the wavelength of the probe's signal as measured by an observer far away increases due to red shift. Hence the statement is false.

2) An observer will see the probe speeding up due to the acceleration. Hence the statement is true.

3) The probe is stretched as the probe approaches the black hole as there will be a difference in acceleration at the front and back of the probe. Hence the statement is true.
