Answer:

B) an electron to move from ground state to an excited state.

Explanation:

Chlorophyll is a pigment that absorbs electromagnetic radiation of the visible spectrum that is used in process of photosynthesis. Chlorophyll's function is to absorb electromagnetic radiation of the visible spectrum and it absorbs blue color radiation the best and green the worst as it reflects it. It absorbs electromagnetic radiation by absorbing the energy of the photon of light by a process called charge separation.

Charge separation is the process by which an electron gets to a higher energy state by absorbing the energy of a photon.

When plugging in metric facts, always remember that 1 big unit = # small units. Fill in these facts: 1.________ s= ________μs 2.
balandron [24]

Answer:

1. 1 s = 1 x 10⁶ μs

2. 1 g = 0.001 kg

3. 1 km = 1000 m

4. 1 mm = 1 x 10⁻³ m

5. 1 mL = 1 x 10⁻³ L  

6. 1 g = 100 dg

7. 1 cm = 1 x 10⁻² m

8. 1 ms = 1 x 10⁻³ s

Explanation:

1.

1 x 10⁻⁶ s = 1 μs

(1 x 10⁻⁶ x 10⁶) s = 1 x 10⁶ μs

<u>1 s = 1 x 10⁶ μs</u>

2.

1000 g = 1 kg

1 g = 1/1000 kg

<u>1 g = 0.001 kg</u>

3.

<u>1 km = 1000 m</u>

<u></u>

4.

<u>1 mm = 1 x 10⁻³ m</u>

<u></u>

5.

<u>1 mL = 1 x 10⁻³ L</u>

<u></u>

6.

1 x 10⁻² g = 1 dg

(1 x 10⁻² x 10²) g = 1 x 10² dg

<u>1 g = 100 dg</u>

<u></u>

7.

<u>1 cm = 1 x 10⁻² m</u>

<u></u>

8.

<u>1 ms = 1 x 10⁻³ s</u>

Jess rides her motorcycle at an average speed of 20 m/s for 500 seconds. how far did she ride
Sedaia [141]

Distance = (speed) x (time)

Distance = (20 m/s) x (500 s)

Distance = (20 x 500) (m·s / s)

Distance = 10,000 m

A ship sails west for 100km and then south for 100km. What is the displacement?
ale4655 [162]

\sf \vec{w}=100

  • \sf \vec{s}=100

For displacement apply Pythagorean theorem

\\ \rm\hookrightarrow 100^2+100^2

\\ \rm\hookrightarrow 10000+10000

\\ \rm\hookrightarrow 20000
