The Earth is not a perfect sphere because it is spinning with respect to most of the universe. The Sun and Moon raise tides on this body and its oceans that drag and exert friction on the planet as it rotates, and the Sun and Moon exert torques on the planet too because of the equatorial bulge. Pick the consequences that:. a. The Moon moving farther away from Earth to conserve system total angular momentum.
b. A speeding up of Earth's rotation.
c. A lengthening of the day by a second every few years.
d. The direction of Earth's axis precessing around the plane of its orbit.

In the derivation of rrkm theory, a factor of 1/2 is introduced when equalizing the rates of formation and decomposition of activated complex as keal-hr) = ko this is clearly against the assumption of transition state theory that states all the activated complex in the transition state iss going to the product. find the reason why this factor is introduced here.

Astudent is performing an experiment comparing sound and light waves. the student gathers the following data. what conclusion does the student most likely make based on this data? light waves always travel the same speed; however, the speed of sound is determined by the medium that it travels through. all sound waves always have the same energy, so the temperature of the medium does not affect wave speed. light needs to vibrate particles, so it travels fastest in tightly packed solids, while sound does not need a medium, so it travels fastest in a gas. tightly packed particles in solids slow down the light waves; however, sound waves make particles bounce into each other, so they travel faster in solids.

Oxygen and nutrients are moved through the body by the: a. circulatory system c. lymphatic system b. digestive system d. reproductive system
