Apile driver drives a post into the ground. the mass of
thepile driver is 2500kg and it is dripped through a height of 8.0m
oneach stroke. if the resisting force of the ground
is4.0*106n, how far is the post driven in on
eachstroke?

They are all solids.

Answerd. may include all of these are many definitions of bases: the  brønsted-lowry definition of acids and bases says that bases are proton acceptors.the arrhenius definition of acids and bases says that bases increase [oh⁻] in solution (thereby producing oh⁻ ions)the lewis definition of acids and bases says that bases donate electron pairs.therefore, the sensible answer is that a base may include all of the described characteristics.
