3. Seismic waves travel faster through rigid rock than through flexible rock. 1 point How would you expect seismic wave speeds to change from the
asthenosphere to the mesosphere. *
Overall, both P and Swaves would INCREASE in speed
Overall, both P and S waves would DECREASE in speed
P waves would DECREASE in speed and Swaves would disappear
O P waves would INCREASE in speed and S waves would DECREASE in speed

Agroup of students is studying convection current. they fill two identical balloons with the same amount of helium. one balloon is placed in a freezer and the other is in an area with warm air. after 10 minutes, the balloon are released from a height of 1 meter. which of the following to the students most likely observe? a) the warm balloon expands and rises. the cold balloon shrinks and sinks b) the balloon both rise. the cold balloon is larger than the warm balloon c) the cold balloon expands and rises. the warm balloon shrinks and sinks d) the balloon rise at the same rate. both balloons are the same size

Malia was able to make a paper clip float on the surface of water what will most likely happen to the paper clip if a drop of dishwashing detergent is added near it

6) (a) calculate the absorbance of the solution if its concentration is 0.0278 m and its molar extinction coefficient is 35.9 l/(mol cm). the depth of the cell is 5 mm. (b) what is the %t? (7) calculate the absorbance of the solution if the transmitted light intensity is 70% of the initial light beam intensity
