Explanation:
6.10 x 10^9 / 3 x 10^5 = 2.033 x 10^4 seconds = 20.33 / 3.6 = nearly 6 hours
.
Answer:
Explanation:
a) the speed=
V=√2gr²/2r
=√gr/2
√10*637/2
V=31850m/s²
Magnitude of the acceleration
a=Gm/r²
10*238/(6370)²
2380/12740
=0.187
Answer: Two high and two low tides
Explanation:
My estimate is 1/2 inch per week.
(0.5 inch/wk) x (1 wk / 7 da) x (1 da / 86,400 sec) x (1 meter / 39.37 inches)
= (0.5 x 1 x 1 x 1) / (7 x 86,400 x 39.37) meter/second
= 1 / 47,621,952 meter/second
= 0.0000000209987... m/s
= 2.1 x 10⁻⁸ meter/second
= 2.1 x 10⁻⁵ mm/sec
= 0.000021 millimeter per second (rounded)
