Answer:
3.6ft
Explanation:
Using= 2*π*sqrt(L/32)
To solve for L, first move 2*n over:
T/(2*π) = sqrt(L/32)
Next,eliminate the square root by squaring both sides
(T/(2*π))2 = L/32
or
T2/(4π2) = L/32
Lastly, multiply both sides by 32 to yield:
32T2/(4π2) = L
and simplify:
8T²/π²= L
Hence, L(T) = 8T²/π²
But T = 2.1
Pi= 3.14
8(2.1)²/3.14²
35.28/9.85
= 3.6feet

We can calculate his resultant speed.
Resultant speed is:
v^2 = 5^2 + 1,9^2
v = 5,349 m/s
Now we need to find angle between resultant speed and vertical speed.
cos(alpha) = 5/5.349 = 0.9347
alpha = 20,8 degrees
Answer is 20,8 degrees

Sample Response:
Explanation:
The root beer exerts a force on all sides of the ice cream. These forces are all equal and cancel each other out. Gravity pushes downward on the ice cream. This can also be called the weight of the ice cream. Buoyant force pushes the ice cream upward. The ice cream floats because the buoyant force is greater than the weight of the ice cream.

Answer:
1- Surface water
2- Groundwater
3- Lake
4- River
5- Watershed/Catchment basin
6- Wetland
Explanation:
- Surface water refers to all the water bodies that are present on the surface of the earth. This includes rivers, streams, ponds, lakes.
- Groundwater refers to the subsurface flow of water. When precipitation occurs, the water percolates downward through the rocks in the region where the rocks are porous and permeable, and this water then becomes groundwater.
- A lake is usually defined as a large water body that is comprised of nutrient minerals and has extensive areas of open water. The depth of the lakes from one place to another and some are so deep that sunlight cannot penetrate into the deeper zone and the plants cannot carry out the process of photosynthesis.
- A river is defined as a water body that flows from a region of higher elevation to the region of lower elevation and it flows across the land surface and configures the landscape.
- Catchment basin is usually defined as a large area in which the precipitation occurs and the waters are accumulated and flow downward and mix up with the river channel and streams.
- Wetlands are usually defined as an ecosystem that is comprised of shallow standing water, and a sufficient amount of vegetation.
