Two balls have the same mass of 5.00 kg. suppose that these two balls are attached to a rigid massless rod of length 2l, where l = 0.550 m.
one is attached at one end of the rod and the other at the middle of the rod.
if the rod is held by the open end and rotates in a circular motion with angular speed of 45.6 revolutions per second,

(a) what is the tension for the first half of the rod, i. e., between 0 and l if the pivot point is chosen as origin?

(b) what is the tension for the second half of the rod, i. e., between l and 2l if the pivot point is chosen as origin?

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.

Tall pacific coast redwood trees can reach heights of about 100 m. if air drag is negligibly small, how fast is a sequola cone moving when it reaches the ground f it dropped from the top of a 100 m tree?

Aboat radioed a distress call to a coast guard station. at the time of the call, a vector a from the station to the boat had a magnitude of 45.0 km and was directed 15.0° east of north. a vector from the station to the point where the boat was later found is = 30.0 km, 15.0° north of east. what are the components of the vector from the point where the distress call was made to point where the boat was found? in other words, what are the components of vector c = b - a?
