Wet Penguins Wet Penguins A rectangular block of ice 14 m on each side and 0.8 m thick floats in sea water. The density of the sea water is 1025 kg/m3. The density of ice is 917 kg/m 1) How high does the top of the ice block float above the water level?
2) How many penguins of mass 15 kg each can stand on the ice block before they get their feet wet?

The vector a? is 3.50 cm long and is directed into this page. vector b? points from the lower-right corner of this page to the upper-left corner of this page and has the components bx=-19.5 cm , by=25 cm. in the right-handed coordinate system, where the +x-axis directed to the right, the +y-axis toward the top of the page, and +z-axis out of the page, find the x-component of the vector product a? ×b? , measured in cm2.
