You are performing an experiment that uses 114ag. 113ag is radioactive, decays by beta-minus emission and has a half-life of 21 minutes. it requires 4.2 hours to ship the material from the warehouse to your laboratory. how many grams should you order if the experiment requires that you have 0.0575 grams to begin the experiment?

Because its reliable.   there is no pollution  the chances of a radiation leak is low

Iassume the answer is 75 feet. inwards to outwards rather than outwards to inwards. probably be 75.hachures are stokes drawn in direction of the steepest slope. a series of short parallel lines drawn on a map to indicate topographic relief. it is actually called hachures on contour lines. the small marks in the center of the feature are called hachures.observe the picture attached

Jenny and fred both play a long note on their trombones. a stationary observer hears the sound increasing and decreasing repeatedly in loudness. which of these must be true? the sound waves from the two trombones have slightly different frequencies.the sound waves from the two trombones have the same frequency.the sound waves from the two trombones have slightly different amplitudes.the sound waves from the two trombones have the same wavelength.the sound waves from the two trombones have slightly different velocities.  lolthe answer is          the sound waves from the two trombones have slightly different frequencies.
