How could seon rewrite his hypothesis to be a statement that will more likely be supported? change the independent variable to “if the angle at which the balloon is launched increases up to 90 degrees . .” change the dependent variable to “if the angle at which the balloon is launched moves closer to 45 degrees . .” change the independent variable to “if the angle at which the balloon is launched moves closer to 45 degrees . .” change the dependent variable to “if the angle at which the balloon is launched increases to 90 degrees. .”

Achlorine atom has 17 protons and 18 neutrons. what is its mass number? what is its atomic number?

Aparticle's position is given by x = 3.00 - 9.00t + 3t2, in which x is in meters and t is in seconds. (a) what is its velocity at t = 1 s? (b) is it moving in the positive or negative direction of x just then? (c) what is its speed just then? (d) is the speed increasing or decreasing just then? (try answering the next two questions without further calculation.) (e) is there ever an instant when the velocity is zero? if so, give the time t; if not, answer "0". (f) is there a time after t = 3 s when the particle is moving in the negative direction of x? if so, give the time t; if not, answer "0".
