Which of the following would be an example of basic research? Experimenting to determine the fundamental properties of x-rays. Spencer's research on WWII radar technology that led to the invention of the microwave oven. Edison's research and use of other scientists' work to invent the light bulb. Morrison and Franscioni's research done to create the Frisbee.
Experimenting to determine the fundamental properties of x-rays.
Which of the following questions can use science as a method of inquiry? Is country music the best or the worst type of music? Do ghosts exist? When is creating a new vaccine appropriate? How did the hole in the ozone layer form?

Suppose an experiment is designed to test the durability of batteries in different conditions. All of the batteries tested are double-A (AA) Brand X. All sets of batteries are preconditioned in different environmental conditions for exactly 168 hours (1 week). Set 1: 0°C (freezing point of water)Set 2: 24°C (approximately room temperature)Set 3: 37°C (approximately body temperature) The batteries are then continuously used to power identical mechanical drummer toys. As long as the toy keeps drumming the battery is considered functional. The drumming time for each toy is measured as an indication of battery durability. Which of the following would be the best hypothesis for the above experiment?
If batteries are affected by the environmental temperature at which it is stored, then it will alter its ability to function.
Look at the following scene. Which of the following statements is an opinion? The spider is going to eat the fly. The spider has at least 8 legs. The fly has wings. The leaf is dead.
The spider is going to eat the fly.
