In this vlab you used a complex machine to launch a projectile with the ultimate goal of hitting a target. assume you built a really big machine that could launch the projectile a “significant” distance; for instance, several hundred miles. write a brief essay discussing the issues that would need to be accounted for with a projectile with that type of range. be sure to include how those issues affect the range of the projectile.

Which graph best represents the relationship between the electric current and the rate at which a magnet is turning inside an electric generator?

Explain the difference between each pair of concepts. a. frequency and relative frequency b. percentage and relative frequency a. select the correct choice below. a. frequency is the total number of observations in a data set. relative frequency is the number of times a particular distinct value occurs. b. frequency is the number of times a particular distinct value occurs. relative frequency is the ratio of the frequency of a value to the total number of observations. c. frequency is the total number of observations in a data set. relative frequency is the ratio of the number of times a particular distinct value occurs to the frequency. d. frequency is the number of times a particular distinct value occurs. relative frequency is the ratio of the frequency of two different values.

Aroller coaster at an amusement park has a dip that bottoms out in a vertical circle of radius r. a passenger feels the seat of the car pushing upward on her with a force equal to four times her weight as she goes through the dip. if r = 23.5 m, how fast is the roller coaster traveling at the bottom of the dip?
