Question

the passage below describes a process of scientific inquiry. select the part of the passage that describes testing the hypothesis. hint: to test the hypothesis, you use experiments or observations to collect data. one afternoon, myra was sliding a heavy book across her desk, and she noticed that it slid less easily across her desk mat than across the wooden desktop. she wondered how a surface’s texture affects the way objects slide across it. myra guessed that it would take less force to slide the book across her smooth tiled kitchen floor than to slide it across a rougher surface, like her desk mat or the living room carpet. myra tied a spring scale to the book. she placed the book at the edge of her desk mat and pulled it using the spring scale, measuring the force it took to get the book to slide. she repeated this process twice. she then repeated the procedure on the tile floor and the carpet. finally, she calculated the average force needed to slide the book on each surface. she observed that it took

Explanation:

Myra ties a spring - scale to the book, places it on different surfaces (desk mat, tile floor, carpet), pulls it with the spring - scale to measure the force needed for the book to slide, repeats the process, and calculates the average force. This is the part where she is using experiments to collect data to test her hypothesis about the relationship between surface texture and the force needed to slide an object.

Answer:

Myra tied a spring scale to the book. She placed the book at the edge of her desk mat and pulled it using the spring scale, measuring the force it took to get the book to slide. She repeated this process twice. She then repeated the procedure on the tile floor and the carpet. Finally, she calculated the average force needed to slide the book on each surface.
