How many hydrogen atoms are in a water molecule?
earnstyle [38]
The subscript after the element indicates the number of atoms of that element in the molecule. So, in H20, the subscript after the H, which stands for hydrogen, is 2. This means that there are 2 hydrogen atoms in a water molecule.

Hope this helps! :)

A device for training astronauts and jet fighter pilots is designed to rotate the trainee in a horizontal circle of radius 11.0
kvv77 [185]

The velocity of the trainee is 29 m/s or 0.42 rev/s

<h3>Further explanation</h3>

Acceleration is rate of change of velocity.

\large {\boxed {a = \frac{v - u}{t} } }

\large {\boxed {d = \frac{v + u}{2}~t } }

<em>a = acceleration (m / s²)v = final velocity (m / s)</em>

<em>u = initial velocity (m / s)</em>

<em>t = time taken (s)</em>

<em>d = distance (m)</em>

Centripetal Acceleration of circular motion could be calculated using following formula:

\large {\boxed {a_s = v^2 / R} }

<em>a = centripetal acceleration ( m/s² )</em>

<em>v = velocity ( m/s )</em>

<em>R = radius of circle ( m )</em>

Let us now tackle the problem!

<u>Given:</u>

Radius of horizontal circle = R = 11.0 m

Force Felt by the Trainee = F = 7.80w

<u>Unknown:</u>

Velocity of Rotation = v = ?

<u>Solution:</u>

F = ma

F = m\frac{v^2}{R}

7.80w = m\frac{v^2}{R}

7.80mg = m\frac{v^2}{R}

7.80g = \frac{v^2}{R}

7.80 \times 9.8 = \frac{v^2}{11.0}

v^2 = 840.84

v \approx 29 ~m/s

\omega = \frac{v}{R}  → in rad/s

\omega = \frac{v}{2 \pi R}  → in rev/s

\omega = \frac{29}{2 \pi \times 11.0}

\omega \approx 0.42 ~ rev/s
