Answer:
Height with sound ignored = Gravity x Time taken = 9.8 x 8.60 = 84.28 meters
Time taken by the sound = 84.28/330 = 0.255 seconds
Height with sound involved = (84.28 x 0.255) + 84.28 = 105.80 meters
a. Underestimated
Answer:
B.It is a satellite that collects data about rain and snow
C.Its orbit covers 90 percent of Earth’s surface
F.The sensors measure microwaves
The naked eye is very limited. Unlike the telescope which can see far away.
F = m * a = 60kg * 2 m/s^2 = 120 N
