<h2>Right answer: Doldrums</h2>
These are also called zones of equatorial calm and it is due a climatic phenomenon that is placed near the Earth equator, attributed to the soft winds, that are called calm winds as well; accompanied by systems of abundant rains and heat.
In this area periods of great calm occur when the winds virtually disappear completely, trapping the sailing ships for long periods (days or weeks). This is why the term <em>doldrum</em> became popular as a colloquial expression in the eighteenth century, to refer to "<em>the caprice of the wind that slows down the navigation to sail".
</em>
The zone is located in the place where two trade winds meet, this means the trade winds of the northern hemisphere <u>converge</u> with those of the southern hemisphere, that is why this region is related to the <u>intertropical convergence zone</u>.
Answer:
The wavelength of sunlight that can cause this bond breakage is 242 nm
Explanation:
The minimum energy of the sunlight that'll break Oxygen-oxygen bond must match 495 KJ/mol
But 1 mole of any molecule contains 6.02 × 10²³ molecules/mol
Each molecule of Oxygen will require (495 × 10³)/(6.02 × 10²³) = 8.22 × 10⁻¹⁹ J
E = hf
v = fλ
f = v/λ
f = frequency of the sunlight
λ = wavelength of the sunlight
v = speed of light = 3.0 × 10⁸ m/s
E = hv/λ
λ = hv/E
h = Planck's constant = 6.63 × 10⁻³⁴ J.s
λ = (6.63 × 10⁻³⁴)(3 × 10⁸)/(8.22 × 10⁻¹⁹)
λ = 2.42 × 10⁻⁷ m = 242 nm.
The medium whose light have the longest wavelength is air.
<h3>What is wavelength?</h3>
The wavelength is the distance between the adjacent crest or trough of the sinusoidal wave. The wavelength is the reciprocal of the frequency of the wave.
Wavelength λ = v/f
where v is the speed of wave in medium.
Given is the chart shows the speed at which light travels through different media.
Medium Speed of light in m/s
Water 2.25 x 10⁸
Air 2.99 x 10⁸
Glass 1.97 x 10⁸
Diamond 1.24 x 10⁸
The speed of light is directly proportional to the wavelength. Greater the speed, greater will be the wavelength.
From the chart, air has the highest speed of light.
Thus, the medium whose light have the longest wavelength is air.

c. Adipose tissue
Explanation:
The type of tissue that most likely will prevent a kidney from floating is an adipose tissue.
- Kidney floating is a rare condition in which the kidney is out of position.
- It is a rare condition in which the kidney drops to the pelvis when they stand up.
- The condition is medically known as nephroptosis.
- It is usually caused when the ligaments attaching the kidney to the body weakens.
- Each kidney is held in place by the renia fascia and is surrounded by the adipose tissues.

The time taken for the ball to reach the ground is determined as 4.32 seconds.
<h3>
Time of motion of the ball</h3>
The time of motion of the ball is calculated as follows;
h = vt + ¹/₂gt²
100 = 2t + (0.5)(9.8)t²
100 = 2t + 4.9t²
4.9t² + 2t - 100 = 0
solve the above quadratic equation using formula method;
a = 4.9, b = 2, c = -100
t = 4.32 seconds
Thus, the time taken for the ball to reach the ground is determined as 4.32 seconds.
