A laboratory is suspected to be contaminated with radiation from a radioactive material. Which of the following detection instruments can be best used to detect this radiation? (5 points) An X-ray film, because it can detect the low frequency X-rays. An X-ray film, because it can detect the low energy infrared radiation. A Geiger counter, because it can detect the high energy gamma rays. A Geiger counter, because it can detect the highly penetrating ultraviolet radiation.

a small container that holds a source of energy a solar cell that captures light energy and converts it into electricity a voltaic cell that uses the oxidation of a fuel to produce electricity

explanation:

the dependant variable is spilled water

the independent is the heat

the volume increases

so here we go

atomic mass

239 + 1 = y + 134 + 3 combine like terms

240 = y + 137             subtract 137 from both terms

240 - 137 = y

103 = y

atomic number

94 = z +54 + 0

94 = z + 54               subtract 54 from both sides.

40 = z
