10) if the coefficient of friction increases, will the force of friction increase or decrease?

Science and technology are interdependent. advances in one lead to advances in the other. give an example of this phenomenon.

If you put a helium-filled balloon in the refrigerator, what will happen?

Emmy kicks a soccer ball up at an angle of 45° over a level field. she watches the ball's trajectory and notices that it lands, two seconds after being kicked, about 20 m away to the north. assume that air resistance is negligible, and plot the horizontal and vertical components of the ball's velocity as a function of time. consider only the time that the ball is in the air, after being kicked but before landing. take "north" and "up" as the positive ‑ and ‑directions, respectively, and use ≈10 m/s2 for the downward acceleration due to gravity.
