This is the world’s coldest biome. it receives only 6-10 inches of precipitation per year and has a permanently frozen layer of earth called permafrost. the soil is nutrient-poor with very little vegetation. a. taiga b. tundra c. deciduous forest d. alpine

Tundra! :) mark me brainiest

b. Tundra

Explanation:

The tundra biome is one of the coldest biome on planet earth. It is characterized by the treeless plains. It receives very low annual precipitation of 6-10 inches. It exhibit extremely cold and low temperatures. It exhibit short growing seasons and lacks vegetation cover due to poor nutrient content of the soil.

given data:

determine the horse power (h.p) = ?

force applied to move the box(f) = 10 pounds,

box lifted from a distance         (d) = 3 feet

time taken to lift                         (t) = 10 sec,

the horse power is defined as amount of work required to move a load. the horse power is equal to 550 foot-pound per second

                  1 h.p   = 550 foot-pound/second

it can also be defined as the the load that need to be move a body for certain distance in a certain amount of time.

mathematically,

                      h.p = (force × distance)/ time

                            = (10 × 3)/ 10

                            = 30/10

                            = 3 foot -pound/sec

hence, the horse power is needed to move the box is 3 foot-pound/second

important note: 1 h.p = 550 foot-pound/second = 746 watts

report!

explanation:

physics means: "the branch of science concerned with the nature and properties of matter and energy. the subject matter of physics, distinguished from that of chemistry and biology, includes mechanics, heat, light and other radiation, sound, electricity, magnetism, and the structure of atoms."
