Answer:
Explanation:
If an object has a higher density than the fluid it is in (fluid can mean liquid or gas), it will sink. If it has a lower density, it will float. Density is determined by an object's mass and volume. If two objects take up the same volume, but have one has more mass, then it also has a higher density.

Answer:
Explanation:
Magnitude of frictional force = μ mg 
μ is either static or kinetic friction. 
To start the crate moving , static friction is calculated .
a ) To start crate moving , force required = μ mg where μ is coefficient of static friction .
force required =.517 x 56.6  x 9.8 = 286.76  N . 
b ) to  slide the crate across the dock at a constant speed , force required 
= μ mg where μ is coefficient of kinetic  friction , where μ is kinetic friction 
= .26 x 56.6  x 9.8 = 144.21 N .
