BTB is an indicator that reacts with CO 2 . Based on the data that you collected in this experi-ment, write a conclusion to the question: Does your body breathe out CO 2 ? State your conclu-sion clearly, and include the evidence from your experiment that supports it.

Suppose a diode consists of a cylindrical cathode with a radius of 6.200×10^−2 cm , mounted coaxially within a cylindrical anode with a radius of 0.5580 cm . the potential difference between the anode and cathode is 260 v . an electron leaves the surface of the cathode with zero initial speed (v initial=0). find its speed vfinal when it strikes the anode.
