Which group of algae is responsible for formation of kelp-beds along north American coasts
fgiga [73]
<span>Along North American coasts, the algae responsible for formation of kelp-beds is Brown Algae. The brown algae (such as seaweed) forms an important part of the ecosystem in marine environments as both a food source and habitat. The formation and structure of the brown algae varies from environment, kelp beds and forests are harvested for human consumption.</span>

Two students are given cubic boxes, measuring 10 cm on a side. Robert puts a single glass marble with a
Katyanochek1 [597]

Answer:

Both boxes have the same amount of empty space

Explanation:

Given

Cube Box

Length = 10cm

Robert:

1 glass marble

Diameter = 10cm

Susan:

1000 glass marble

Diameter = 1cm

Required

Whose box has more empty space?

First, we need to calculate the volume of the cubic box.

Volume = Length^3

Substitute 10cm for Length

Volume = 10^3

Volume = 1000cm^3

Next, calculate the volume of Robert's glass

Volume is calculated as:

Volume = \frac{4}{3}\pi r^3 ---- Volume of a sphere

Where

r = radius

r = \frac{1}{2} * Diameter

Diameter = 10cm --- Given

Substitute 10 for diameter

r = \frac{1}{2} * 10cm

r = 5cm

So:

Volume = \frac{4}{3}\pi r^3

Volume = \frac{4}{3} * \frac{22}{7} * 5^3

Volume = \frac{4}{3} * \frac{22}{7} * 125

Volume = 523.8cm^3

Next, we determine the volume of Susan's 1000 glasses

Volume is calculated as:

Volume = \frac{4}{3}\pi r^3 ---- Volume of a sphere

Where

r = radius

r = \frac{1}{2} * Diameter

Diameter = 1cm --- Given

Substitute 1cm for diameter

r = \frac{1}{2} * 1cm

r = 0.5cm

Substitute 0.5cm for radius in Volume = \frac{4}{3}\pi r^3

Volume = \frac{4}{3} * \frac{22}{7} * 0.5^3

Volume = \frac{4}{3} * \frac{22}{7} * 0.125

Volume = 0.5238

But there are 1000 glasses.

So, the volume of 1000 glasses is:

Volume = 0.5238 * 1000

Volume = 523.8cm^3

--------------------------------------------------------------------------------------------------------------

For Robert:

Volume = 523.8cm^3

For Susan:

Volume = 523.8cm^3

Since, they have the same volume.

Both boxes have the same amount of empty space
