Lucia wants to change the motion map shown so that it shows uniform circular motion.

an illustration of a circle with four black dots on the top, bottom, left and right of the circle. each dot has a vector toward the center of the circle and a vector tangent to the circle in a counterclockwise direction.

what change should lucia make?

she should change the length of each vector that is tangent to the circle so that it is the same as the vector pointing toward the center at that point.

she should change the direction of the vectors that are toward the center of the circle so that each points tangent to the circle opposite the existing tangent vectors.

she should change the direction of the vectors that are toward the center of the circle so that each points away from the center of the circle.

she should change the lengths of the vectors that point toward the center so that each is the same length.

On a recent expedition to a remote region of northern canada, scientists uncovered skeletal remains from about 100,000 years ago. surprisingly, all the skeletal remains, which included many species from differing biological families and spanned about two thousand years, showed evidence of experiencing temperatures in excess of 1000 degrees fahrenheit (or 538 degrees celsius). which of the following, if true, best explains the apparent paradox between the cold environment and the evidence of the bones experiencing hot temperatures? (a) chemical changes that naturally occur during the process of decay in only one north canadian species produce the same evidence of the species' skeletons being exposed to hot temperatures as the expedition scientists found. (b) a little over 103,000 years ago, a large fire is known to have occurred in northern canada. (c) strong evidence exists that as early as 70,000 years ago, homo sapiens around the world relied heavily on fire to cook animals. (d) in the same expedition and in roughly the same layer of excavation, scientists found rudimentary wood cutting and hunting tools used by early humans.
