What are some examples in applied research?

OK. Experimental reseach is basically research about what your topic is. For example, if you are measuring the effect of different types of air in balloons, you might want to ask research questions such as "What is helium" or "What type of air is released when I blow into the balloon" or maybe even "What types of things can alter the result of my experiment?" There are so many questions out there. Just make sure you give background information, studies, procedures, and equiptments. I hope this helped you!to ask me the example of expirement?::)
