Most people today know that the ocean tides are caused principally by the gravitational influence of the Moon, and most people therefore think that the gravitational pull of the Moon on Earth is greater than the gravitational pull of the Sun on Earth. What do you think?
What is surface tension? What is its cause? Why is the surface tension also called surface energy?
Rockets are launched into space from Cape Canaveral in an easterly direction. Is there an advantage to launching to the east versuslaunching to the west? Explain.

Go to the park entrance and face the north direction. Then, walk straight ahead towards the first bench you see, about 70 meters from the entrance. Face east then turn as you count about 63 º degrees towards the north direction and you'll see a tree with a birdhouse near the bank of the river, just about 307 meters from the bench. Go there.

- 2. Show that the divergence of the geostrophic wind is – v,(cot $)/a if the variations in fwith latitude are accounted for (i.e., use the full definition of the Coriolis parameter f = 2.0 sin p). To derive this relationship, recall that on a spherical planet, the distance north is y = aø, where ø is latitude (in radians) and a is the radius of Earth (6,370,000 m). Thus, a derivative in y can be expressed as a derivative in latitude o via the following relationship: a 1 a ду а дфarrow_forwardWhich of the following could explain a gradual warming trend in a planet's climate?

The pressure at sea level on Earth is 1 Bar, a unit that equals 100,000 Newtons per square meter of ground under Earth's gravity.
