Answer:
Explanation:
7) A block of wood
has a length of 10.2
cm, a width of 6 cm
and a height of 4.1
cm. The wood has
a total mass of 179
grams. What is the
volume of the
wood and what is
the density of the
wood?
volume = L XW XH=10.2 X 6 X4.1 =250.92cm^3
DENSITY = M/V = 179gm/250.92 cm^3
=0.713 gm/cm^3

Answer:
Reaction Force!!
Explanation:
The diver moves “forward" and dives into the water. The raft moves "backwards” in the water because of the reaction force. The action force is the diver pushing off of the raft, and the reaction force is the raft pushing back on the diver (causing the diver to go forward and into the water).
Hope this helps you!!!
Older trees can survive with the bark stripped from up to half the trunk diameter. If the bark is stripped all the way around the tree, it will die unless the damage can be repaired with bridge grafts.
