Answer:
Δx = 39.1 m
Explanation:
- Assuming that deceleration keeps constant during the braking process, we can use one of the kinematics equations, as follows:
where vf is the final velocity (0 in our case), v₀ is the initial velocity
(25 m/s), a is the acceleration (-8.0 m/s²), and Δx is the distance
traveled since the brakes are applied.
- Solving (1) for Δx, we have:
A. 4% you divide 2000 to 500 and you get 4 which is your answer
Any type of wetland that has been developed or maintained by humans for uses such as aquaculture, irrigation, or water storage.
<h3>What is a human-made wetland ?</h3>
Any kind of wetland that has been created or kept up by people for purposes like water storage, irrigation, or aquaculture.
In India's Punjab state, in the Kapurthala district, lies the man-made Kanji Wetland, which includes the Kanji Lake.
In order to give irrigation facilities to the hinterland, it was built by building the headworks over the perennial Bien River, a tributary of the Beas River.
The Sunderbans are India's biggest wetland. The world's biggest mangrove forest includes Sunderban Wetland.
Hence, the human-made wetland is an artificial wetland.

The height of the flare relative to ground is 202.3 m. <em>This is the sum of height reached by the flare and the 3 m platform above the ground.</em>
<h3>
Maximum height reached by the flare</h3>
The maximum height reached by the flare is determined from the principle of conservation of energy as shown below;
P.E = K.E
mgh = ¹/₂mv²
gh = ¹/₂v²
h = (v²)/(2g)
where;
- v is the speed = 225 km/h = 62.5 m/s
h = (62.5)²/(2 x 9.8)
h = 199.3 m
<h3>Height of the flare relative to ground</h3>
H = 199.3 + 3
H = 202.3 m
Thus, the height of the flare relative to ground is 202.3 m. This is the sum of height reached by the flare and the 3 m platform above the ground.
