Uniform circular motion is used in physics to describe the motion of an object traveling at a constant speed in a circle. the speed of the object is called tangential velocity and it can be calculated using the formula above, where r is the radius of the circle and t is the time is takes for the object to make one complete circle, called a period. which of the following formulas could be used to find the length of one period if you know the tangential velocity and the radius of the circle?

Write the contrapositive of the conditional statement. determine whether the contrapositive is true or false. if it is false, find a counterexample. a converse statement is formed by exchanging the hypothesis and conclusion of the conditional. a) a non-converse statement is not formed by exchanging the hypothesis and conclusion of the conditional. true b) a statement not formed by exchanging the hypothesis and conclusion of the conditional is a converse statement. false; an inverse statement is not formed by exchanging the hypothesis and conclusion of the conditional. c) a non-converse statement is formed by exchanging the hypothesis and conclusion of the conditional. false; an inverse statement is formed by negating both the hypothesis and conclusion of the conditional. d) a statement not formed by exchanging the hypothesis and conclusion of the conditional is not a converse statement. true
