12. Given that the Force of gravity on moon is only 1/6th as strong as on earth, if you drop a ball on moon's surface and it falls 12 second before hitting ground. What is the maximum speed that the ball attains? A. 19.8m/s B. 19.8m C. 117.6m/s D. 9.8m/s E. It won't fall to ground 3. Water at 4"C has the density, which means it contracts when its temperature- -4°C and expands when its temperature4'C A. Smallest, moves away from, approaches B. Largest, is below, is above C. Smallest, approaches, moves away from D. Largest, approaches, moves away from E. Largest, moves away from, approaches

Explanation / Answer

2.

t = 12 s, a = 10/6 m/s^2 = 1.66m/s^2

v= u+at = 0 + (1.66*12) = 19.8 m/s

3.

D. Largest, approaches, moves away from
