A scientific technique can be used to determine the presence and concentration of a chemical compound in a sample. A light source is directed at samples of known concentrations and the amount of light each absorbs is measured. Based on the graph, which statement best describes the relationship between concentration and light absorption? A. The light absorption of a sample is independent of the concentration of the chemical compound.
B. The concentration of the chemical compound in a sample remains steady as the light absorption increases.
C. An increase in the concentration of the chemical compound in a sample is accompanied by an increase in the light absorption.
D. A decrease in the light absorption of a sample is accompanied by an increase in theconcentration of the chemical compound.

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

explanation:

considering the bohr theory, the type of connection that requires the transfer the answer conuldn't be right

answer: 31, 5556. 952 seconds
