Answer:
The cyclist’s displacement is +5 m.
Explanation:
We have, A cyclist starts at a position of origin. He takes 3 s to move east to a position of +8 m. He then cycles west to a position of +5 m which takes an additional 2 s.
It is required to find the cyclist’s displacement. Displacement of an object is the shortest path covered by it or it is given by the difference of final to the initial position.
Finally, he cycles west to a position of +5 m. Distance between final and initial position is +5 m.
Hence, the cyclist’s displacement is +5 m.
Answer:
Blue Cypress Lake, originally called Lake Wilmington, is a lake in Indian River County of the Treasure Coast in Florida. It is the largest lake in the Treasure Coast and Indian River County. It is the headwaters lake of the St. Johns River. The sources of water are several creeks from the south (Mudfish Slough, Padget Branch, Holman Canal, and Fisher Creek), two from the west (Trim Creek, Blue Cypress Creek), and Moonshine Bay from the North that flow into the lake. All the water flows out of the lake to the northwest into M Canal and Zigzag Canal. The lake is over 6,500 acres (26 km²) in size, 21 mi (34 km) in circumference, and has an average depth of 8 feet (2 m). The lake is 2,100 acres (8.7 km²) larger than Lake Washington, 27 mi (43 km) north of this lake. The lake's name comes from the blue appearance of the cypress trees as the morning sun's rays reflect off the water. A fishing camp called Blue Cypress Lakeside Cabins is 4 mi (6 km) off State Road 60. The Blue Cypress Village (about 70 units) is south of the small boat canal from the fish camp.

B is the answer! Hope this helps :)
The given is incomplete as the options are missing. The correct options for the given question are as follows-
(A) cultivation of agricultural land inhibits the decomposition of organic matter
(B) nitrogen-fixing bacteria are not as plentiful in agricultural soils because of the use of pesticides
(C) land that is available for agriculture tends to be nutrient-poor
(D) the nutrients that become the biomass of plants are not cycled back to the soil on lands where they are harvested
Answer:
Option (D)
Explanation:
In order to carry out agricultural practices, the soil must be rich in essential nutrients for the growth of crops. The soil fertility is a key role in the production of crops.
This agricultural land often requires a large amount of these nutrients and minerals because some of the nutrient minerals are converted into plant biomass which is then used up to produce energy in other sectors. So, the nutrients that were present in the soil are taken away and not transferred back into the soil. This means that the nutrient cycle gets affected. Due to this reason, there requires a constant supply of nutrients into the agricultural fields.
Thus, the correct answer is option (D).
