If you wanted to develop a lighting apparatus (e. g., series of bulbs or tubes) that people in alaska could use to grow vegetables indoors year-round, which wavelengths should you include in your product?

Blue and Red

Explanation:

Blue Light

The blue wavelengths are from 430 to 450 nm. This part of the spectrum is also known as cool light. These wavelengths encourage vegetative growth through strong root growth and intense photosynthesis.

Red Light

The longer wavelengths of light are red in color. The red spectrum are from 640 to 680 nm. These wavelengths encourage stem growth, flowering and fruit production, and chlorophyll production.

Both are very important in winter time (Alaska's case)

gpe = mass x gravity constant x height or… gpe = mgh

where… mass: measured in kilograms (kg)

gravity: gravity constant on earth = 10.00 m/s2

height: measured in meters (m)

gpe: measured in joules (j) or kilojoules (kj)

how do you solve gpe?

gravitational potential energy (gpe) is the energy an object has because of its position above the. ground.

gpe = mass x gravity constant x height or… gpe = mgh.
