Truvia is running. Their velocity as a function of time is show below. Use the graph to calculate the acceleration of Truvia from t = 13 s to t = 18 s

think about the oscillation of the toy shown in the video. when the toy is at the highest point of its motion, its velocity is zero and its acceleration is negative.

it has to be b, about 97 percent.

beta is electron from nucleus

something from nucleus has changed, but charge must be same for cons of charge
