An astronaut on a strange new planet having no atmosphere finds that she can jump up to a maximum height of 27 m when her initial upward speed is 6.0 m/s. What is the magnitude of the acceleration due to gravity on the planet?
What will be an ideal response?
Question 2
During operation of a nuclear reactor, the 238U nuclei
A) absorb neutrons, which causes them to turn into plutonium.
B) slow down the neutrons, thus improving the efficiency of the reactor.
C) absorb neutrons, which causes them to turn into fissionable 235U.
D) absorb neutrons, which slows down the chain reaction and thus controls the reaction.
E) are fissioned by the neutrons, thus releasing nuclear energy.
