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.

Answer:
a fish cannot be killed by throwing an arrow into the water because you have to throw the arrow at the fish not just in the water….

Answer:
v = 1.15*10^{7} m/s
Explanation:
given data:
charge/ unit area
plate seperation = 1.69*10^{-2} m
we know that
electric field btwn the plates is
force acting on charge is F = q E
Work done by charge q id
this work done is converted into kinectic enerrgy
solving for v
v = 1.15*10^{7} m/s
F= (speed)/(wavelength)
Therefore, speed = Frequency x wavelength
V = 68m/s
