Iam doing a test to see if there is a connection between how long you run and how fast your heart beats. i will be performing an experiment where a person will run for a 1 minute and i will check their heart beat. then they will run for 2 min and i will check their heart rate. i will do this up to 6 min and see if there is a connection. what do you think my hypothesis should be? what are my variables?
independent
dependent

increase soil erosion                                             reduce soil erosion

cattle grazing                                                         hydroseeding

deforestation                                                         contour plowing

                                                                                planting vegetation

plant roots basically hold the top soil

together and stop soil erosion because

in such situation top soil is not removed

during flood but cattle grazing causes

soil erosion because cattle consume the

grasses and herbs and top soil is exposed.

same situation occurs because of

deforestation, the trees and plants are cut

down to expose top soil which causes soil

erosion

explanation:

the universal gravitation equation. since the gravitational force is directly proportional to the mass of both interacting objects, more massive objects will attract each other with a greater gravitational force. if the mass of one of the objects is doubled, then the force of gravity between them is doubled.
