A hockey puck wont slide very far on concrete or asphalt, but it will slide for a very long time on ice. Why is this?

Answer:

Concrete and Asphalt are much rougher surfaces and have a higher coefficient of friction because they generate more resistance to an object in motion. Ice has less friction and less energy is lost to heat, causing the puck to slide much further.

When hockey players push the puck along the ice it slides causing heat which melts the ice causing the friction against the ice to be less.

) determine the density of a 32.5 g metal sample that displaces 8.39 ml of water.

sweet-ann [11.9K]

Density is the ratio of a substance's mass to its volume. On the other hand, according to Archimedes' principle, the volume of water displaced is equal to the volume of the object placed on the water. Thus, the density of the metal is equal to 8.39 mL. So, the density would be

Density = 32.5 g/8.39 mL = 3.87 g/mL
