Q. Two horses pull horizontally on ropes attached to a stump. The two forces F1 ⃗⃗⃗⃗ and F2 ⃗⃗⃗⃗ that they apply to the stump are such that the net (resultant) force R⃗ has a magnitude equal to that of F1 ⃗⃗⃗⃗ and makes an angle of 90° with F1 ⃗⃗⃗⃗ . Let F1 = 1300N and R = 1300N also. Find the magnitude of F2 ⃗⃗⃗⃗ and its direction (relative to F1 ⃗⃗⃗⃗ ).

1) sections 1, 2, and 10 are significant primarily because they suggest the likelihood that a) widow wycherly is actually the woman in the full-length portrait. b) dr. heidegger wants to include his guests in an experiment with the water. c) dr. heidegger plans to drink some of the water from the vase and needs witnesses. d) the guests will be asked to witness dr. heidegger's transformation when he drinks the water.

What causes the development of most clouds and precipitation in the atmosphere?

1. when conducting a test on what kind of music increases the growth of plants, all of the following would fail to meet to fair test standard except (1 point) using different kinds of plants. giving some plants more water than others. exposing the plants to different types of music. using nutrient-rich soil for one and lesser soil for others. 2. engineering uses scientific thinking to solve real-world problems. (1 point) true false 3. what does it mean to test a hypothesis? (1 point) pass a quiz on other scientists’ results analyze only the results from scientific sources not make assumptions about how an experiment will turn out see if the results of an experiment are what the scientist predicted
