6. In both cases, a massless rod is supported by a fulcrum, and a 200-kg hanging mass is suspended from the left end
of the rod by a cable. A downward force F keeps the rod at rest. The rod in case A is 50 em long, and the rod in
case B is 40 cm long. (Each rod is marked at 10-centimeter intervals.)

Will the magnitude of the vertical force F exerted on the rod be (a) greater in case A. (b) greater in case B, or (c)
the same in both cases?

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.

Erosion of the beach is normally a slow process. however, in certain situations, large chunks of shore may wash out to sea. what could cause this to happen?
