Answer:

1.4 g/cm³  

Step-by-step explanation:

1. Calculate the <em>volume of the block</em>

V = lwh

<em>Data: </em>

l   = 150     cm

w =     0.20  m

h  =     6.0 mm

(a) Convert all units to a <em>common base </em>

w  = 0.20 m × (100 cm/1 m)

w  = 20 cm

h   =    6.0 mm × (1 cm/10 mm)

h   =    0.6 cm

<em>Calculation: </em>

V = lwh

V = 150 × 20 × 0.60

V = 1800 cm³

2. Calculate the <em>density </em>

Density = mass/volume

<em>Data: </em>

m = 2.5 kg

<em>Calculation: </em>

m = 2.5 kg     Convert to grams

m = 2.5 kg × (1000 g/1 kg)

m = 2500 g

Density = 2500 g/1800 cm³

Density = 1.4 g/cm³

Answer:

Its job is to store light

Explanation:

Green plants have the ability to make their own food. They do this through a process called photosynthesis, which uses a green pigment called chlorophyll. ... Chlorophyll's job in a plant is to absorb light—usually sunlight. The energy absorbed from light is transferred to two kinds of energy-storing molecules.
