State a problem. Describe what you want to find out about the relationship of the factors to the amount of water that occurs on a slope: slope gradient (steepness), presence or absence of vegetation, and rain intensity. All factors must be included in your answers for 1 & 2. Make a hypothesis about how variables such as the slope of the soil, the presence, or absence of vegetation, and the intensity of rain affect the erosion of soil by water.

Awheelhas a radius of 4.8 m. howfar (path length) does a point on the circumference travel if thewheel is rotated through angles of 30°, 30 rad, and 30 rev, respectively?

In an old-fashioned amusement park ride, passengers stand inside a 3.0-m-tall, 5.0-m-diameter hollow steel cylinder with their backs against the wall. the cylinder begins to rotate about a vertical axis. then the floor on which the passengers are standing suddenly drops away! if all goes well, the passengers will “stick” to the wall and not slide. clothing has a static coefficient of friction against steel in the range 0.60 to 1.0 and a kinetic coefficient in the range 0.40 to 0.70. part a what is the minimum rotational frequency, in rpm, for which the ride is safe? express your answer using two significant figures. f f = rpm
