A disk of mass 5.25kg and radius 0.563m is rotating horizontally about a frictionless axle, with angular velocity 3.23 rad/s. Someone drops a thin hoop of mass 2.00kg and radius 0.110m such that it lands on the disk, but it is not dropped over the center of the disk. The hoop and disk spin as a single object with final angular velocity 2.70 rad/s. How far is the hoop’s center of mass from the axle? Treat the disk as a uniform disk.

Which statement best describes resistance? resistance is a. how well a current will flow in a material and is measured in volts. b. how well a material conducts an electrical charge and is measured in ohms. c. the ability of a material to attract a positive charge to create a current. d. the ability of a material to repel neutral charges and is measured in ohms.

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.

You are given two vectors a⃗ =−3.00ι^ 5.00j^ and b⃗ =5.00ι^ 2.00j^. let the counterclockwise angles be positive.
