The primary difference between a boundary crossing and a boundary violation is: a. everyone agrees when a boundary has been violated, whereas it is hard to reach agreement as to whether a boundary has been crossed. b. a violation involves a sexual relationship. c. a crossing occurs in almost every counseling session, while violations are less frequent. d. in a crossing, a boundary is shifted to meet the needs of the counselor, making sure the client is not harmed in the process. e. a violation involves a serious breach of the code of ethics that results in a client being harmed.

the correct answer is 2.

a slump in geology means a mass movement process of slope failure. a mass of rock or unconsolidated material drops along a slip surface. in other words, rock layers move a short distance down the slope. the slump block is an intact block (2), without any landslide material.

in this image, 1 is the surface of rapture (scarp), 2 the slump block, 3 main scarp (crown), 4 base of rapture with debris flow.

slumps are caused by clear cutting on unstable soils and the sagging of earth, in coastal areas they are due to wave infiltration.

we can solve this via the kinematic equation:

where the vertical velocity is zero and so:

since the height of the building is 29.3 meters then:

the ball was in motion for approximately 2.45 seconds
