Answer:

The answer to your question is the third one

Explanation:

Check which reaction is balanced

a)                           CO₂ + 2H₂0 → 2CH₄ + 20₂

                      Reactants                          Products

                            1                   C                    2

                            4                  H                    8

                            4                  O                    4

This reaction is unbalanced because the number of reactants is different from the number of products.                  

b)                              CH₄ + O₂ → CO₂ + H₂O

                    Reactants                          Products

                            1                   C                    1

                            4                  H                    2

                            2                  O                    3

This reaction is unbalanced because the number of reactants is different from the number of products.        

c)                         CH₄ + 20₂ → CO₂ + 2H₂O

                    Reactants                          Products

                            1                   C                    1

                            4                  H                    4

                            4                  O                    4

This reaction is balanced because the number of reactants is equal to the number of products.        

d)                          CO₂ + H₂O → CH₄ + O₂

                    Reactants                          Products

                            1                   C                    1

                            2                  H                    4

                            3                  O                    2

This reaction is unbalanced because the number of reactants is different from the number of products.

snow_tiger [21]
I believe that solar energy would be the best energy for my town.  Solar energy is advantageous because the sun is up every day, and because it takes up much less space than than some other sources of renewable energy.  Some disadvantages of solar energy are that if there is cloud cover, hardly any energy will be gained at all.  Another disadvantage is that it is a long term investment that can take a while for it to pay for itself.

Standing waves can ruin the acoustics of a concert hall if there is excessive reflection of the sound waves that the performers
Dmitrij [34]

Answer:

The answer to the questions is;

In terms of standing waves, the listener moves from a location with high amplitude to one with lower amplitude or vibration (anti-node to node)

The distance 4.1 cm is equivalent to λ/4

Explanation:

For standing waves we have is a stationary wave comprising of two opposite direction moving waves that have equal amplitude and frequency, resulting in the superimposition of the waves. As such certain points are fixed along the wave path that is the peaks amplitude of the wave oscillation is constant at a particular point. A node occurring at a point and an anti-node occurring at another fixed point

When the listener moves 4.1 cm he or she has left the anti-node to the node hence the faintness of the sound

The distance from the node to the anti-node is 1/4 wavelength, or 1/4×λ

Therefore 4.1 cm is λ/4

Find the separation of two points on the Moon’s surface that can just be resolved by the 200 in. (= 5.1 m) telescope at Mount Pa
rewona [7]

Answer:

The separation of the 2 points should be 50.0 meters.

Explanation:

According to Rayleigh's scattering criteria the angular separation between 2 points to be resolved equals

\theta =1.22\cdot \frac{\lambda }{D}

Applying the given values we get

\theta =1.22\cdot \frac{550\times 10^{-9} }{5.1}=0.1316\times 10^{-6}rads

thus the linear separation equals L=\theta \times Distance

Applying the given values we get

L=0.1316\times 10^{-6} \times 3.8\times 10^{5}\times 10^{3}meters\\\\\therefore L=50.00metes

The default unit of rotational speed is 'radians per second' or 'rad/s'. If a someone sits at the edge of a 5m radius carousel a
Blizzard [7]

The rotational speed of the person is 0.4 rad/s.

<h3>Rotational speed (rad/s)</h3>

The rotational speed of the person in radian per second is calculated as follows;

v = ωr

where;

  • v is linear speed in m/s
  • r is radius in meters
  • ω is speed in rad/s

ω = v/r

ω = 2/5

ω = 0.4 rad/s

Thus, the rotational speed of the person is 0.4 rad/s.
