Aspeedboat travels from the dock to the first buoy, a distance of 20 meters, in 18 seconds. it began the trip at a speed of o m/s. by the time it reached the buoy, it was going 10 m/s. what was the average velocity of the boat? a) -3.33 m/s^2 b) -1.11 m/s c) +1.11 m/s d) +3.33 m/s

Your pendulum clock which advances 1.0 s for every complete oscillation of the pendulum is running perfectly on earth at a site where the magnitude of the acceleration due to gravity is 9.80 m/s2. you send the clock to a location on the moon where the magnitude of the acceleration due to gravity is 1.65 m/s2.

According to newtons universal law of gravitation, which would change the parh of the ball so it traces out widest curved path possible?

Although longitudinal waves can travel through all media types what is the disadvantage of this type of wave transmission? a) he efficiency of he wave transmission is greatly diminished as the media becomes less dense b) the oscillation of one set of particles has a huge impact on neighboring particles c) particles become too close together as they bump into each other making it more likely to hit other particles down the line
