Packet B: Bonus 2

This physicist discovered an effect in which Earth’s measured gravitational acceleration depends on the direction a ship is traveling. For 10 points each:
[10h] Name this physicist who names a unit equal to 10 to the negative ninth gals per centimeter, the unit of gravitational gradient.
ANSWER: Loránd Eötvös (“UT-vush”) [or Baron Loránd Eötvös de Vásárosnamény; or Eötvös Loránd; accept Eötvös effect]
[10e] The magnitude of the Eötvös effect is proportional to this function of the latitude. The normal force on an inclined object is proportional to this trigonometric function of the angle, which equals 1 at zero degrees.
ANSWER: cosine [or cos]
[10m] Eötvös more famously used a torsion balance to demonstrate this principle. The weak version of this principle states that gravitational mass and inertial mass are identical.
ANSWER: equivalence principle [accept weak equivalence principle]
