Answer:

Two oxygen atoms

Explanation:

The majority of the oxygen in the air in our atmosphere consists of molecular oxygen ( $O_2$ ), which consists of 2 atoms of oxygen, since free oxygen mainly form covalent bonds with other atoms of oxygen.

A small fraction of the oxygen, however, in the ozone form, which consists of 3 atoms of oxygen bond together ( $O_3$ ).

This question involves the concepts of the law of conservation of energy and kinetic energy.

The girl's fastest speed is "3.7 m/s".

According to the law of conservation of energy, the girl will have the fastest speed at mean position, which will be calculated as follows:

Loss in Potential Energy = Gain in Kinetic Energy

$mg\Delta h=\frac{1}{2}mv^2\\\\v=\sqrt{2g\Delta h}$

where,

v = maximum speed = ?

g = acceleration due to gravity = 9.81 m/s²

Δh = change in height = 1.3 m - 0.6 m = 0.7 m

Therefore,

$v=\sqrt{2(9.81\ m/s^2)(0.7\ m)}$

v = 3.7 m/s

In three to four sentences, explain how climate change could impact the formation of hurricanes. (4 points)

daser333 [38]

The climate change can directly impact the formation of hurricanes because increasing temperature increases intensity of hurricanes.

<h3>How climate change could impact the formation of hurricanes?</h3>

Evaporation increases as temperatures rise which also causes the transfer of heat from the oceans to the atmosphere. As the storms travel across oceans whose water is warm, they absorb more water vapor and heat which increases rainfall as well as intensity of hurricanes.

So we can conclude that the climate change impacted the formation of hurricanes due to increasing temperature that increases intensity of hurricanes.

A wave with a frequency of 17 Hz has a wavelength of 4 meters. At what speed (in m/s) will this wave travel?

Molodets [167]

Answer:68m/s

Explanation:

Frequency=17Hz

Wavelength=4metre

Wave speed=frequency x wavelength

Wave speed =17 x 4

Wave speed =68m/s
