Select the mismatched pair. Select one: a. root - root canal b. alveoli - periodontal ligament c. crown - enamel d. apical foramen - blood supply e. pulp cavity - cementum

a. as the temperature increases, the kinetic energy of the gas molecules increases & the molecules move faster & further away from each other.

b. if you decrease the temperature of a fixed amount of gas at constant pressure, the combined gas law reduces to charles's law. in this case, volume will also decrease.

the answer is; comparing the frequency of collisions with and without the device

this makes the anti-collision system an independent variable and the collisions a dependent variable. if there are fewer collisions with an anti-collision system that without, then it can be stated that the system is a success. essentially, collisions under an anti-collision system are compared with the frequency of collisions by cars with the human drivers.

b. to discover aspects of the natural world.

hopefully i .

idk im sorry.
