Cellphone radiation travels in the form of nonionizing radiation and is
measured with a field strength meter. Cellphones that need more reception emit
high levels of radiating waves, while cellphones near towers require less work to do
Purpose: To explore Half-life of a Radioisotope
Introduction: In this lab you will investigate radiometric dating. The
pennies represent the radio nuclide contained in our sample. An
unstable nucleus decays in order to achieve a new nucleus that is

1. A whistle you use to call your hunting dog has a frequency of 21 kHz, but your
dog is ignoring it. You suspect the whistle may not be working, but you can't hear
sounds above 20 kHz. To test it, you ask a friend to blow the whistle and hop on

Part A: Review Variables
The focal length of the lens is determined by the curve of the lens and the
material of the lens. At the virtual site, the focal length of the lens defaults to
10.0 cm. Also, the variables used in the simulation are not
Module 5 Honors ext.
As pollution increase, there is a necessity for renewable or
alternate power sources. A clean way of producing energy is from a
method called hydro-electrical energy. The method is actually very
