A2.0-cm-thick bar of soap is floating on a water surface
sothat 1.5 cm of the bar is underwater. bath oil of specific
gravity0.60 is poured into the water and floats on top of the
water. whatis the depth of the oil layer when the top of the soap
is justlevel with upper surface of the oil?

The midpoints? a, b, and c are marked on the histogram. match them to the indicated scores. which? scores, if? any, would be considered? unusual?

What part of the ear is names after tools, such as the hammer and the anvil?

Aparticle's position is given by x = 3.00 - 9.00t + 3t2, in which x is in meters and t is in seconds. (a) what is its velocity at t = 1 s? (b) is it moving in the positive or negative direction of x just then? (c) what is its speed just then? (d) is the speed increasing or decreasing just then? (try answering the next two questions without further calculation.) (e) is there ever an instant when the velocity is zero? if so, give the time t; if not, answer "0". (f) is there a time after t = 3 s when the particle is moving in the negative direction of x? if so, give the time t; if not, answer "0".
