Sea turtle researchers decided to install cameras at a nearby beach to capture images of any turtles that visited the beach during the night. The researchers were careful to select and install cameras that would not be detected by the sea turtles, ensuring they would not be disturbed. Uses and Dangers of the Electromagnetic Spectrum Wave Type Uses Dangers infra-red remote controls, thermal imaging can burn skin micro microwave ovens, communication systems can heat internal body tissue ultra-violet detergents, security marking can cause skin cancer and blindness visible spectrum light sources, optic fibers can cause damage to eyes Which type of electromagnetic waves should the scientists’ cameras use in order to safely capture images of the sea turtles at night?

An experimental procedure requires a 10 ml of acid to be dissolved

Chlorine and water react to form hydrogen chloride and oxygen, like this: 2cl2 (g) + 2h2o (g) → 4hcl (g) + o2 (g) also, a chemist finds that at a certain temperature the equilibrium mixture of chlorine, water, hydrogen chloride, and oxygen has the following composition: compound concentration at equilibrium cl2 0.55m h2o 0.57m hcl 0.53m o2 0.34m calculate the value of the equilibrium constant kc for this reaction. round your answer to 2 significant digits.

Electromagnets coils of wire paper clips picked up 10 3 15 6 20 9 25 12 ms. owens' class was studying magnets. ms. owens showed her students how to make an electromagnet using a nail, a d-cell battery, and plastic coated wire. the students wrapped the wire around the nail and then attached the ends to the battery. when they were finished, they tested their magnets by investigating how many paperclips their magnets could pick up. they also tested whether they could increase the strength of their electromagnets by using more coils of wire. they recorded the class average of their results in the data table seen here. ms. owens asked her students to graph their data in a line graph. how should the students label the x-axis on their line graph? a) size of battery b) number of paper clips c) number of coils of wire d) strength of electromagnet
