2.4 g/cm3We learned this in my physics class as well.

p = m/v</span></span>
Where:
p = density
m = mass
V = volume
So to find the density you solve 36/16
=2.4
Hope this helped. Have a great day!
Answer:
(-1.5,-1.5)m
Explanation:
we know that:
where 
is the location of the center of gravity in the axis x, 
is the mass of the object i and 
the first coordinate of center of gravity of object i.
so:
Where 
is the first coordinate of the center of gravity for the fourth object.
Therefore, solving for , we get:
At the same way:
where 
is the location of the center of gravity in the axis y, is the mass of the object i and 
the second coordinate of center of gravity of object i. replacing values we get:
Where 
is the second coordinate of the center of gravity for the fourth object.
solving for :
It means that the object of mass 8kg have to be placed in the
coordinates (-1.5,-1.5) m.
Answer:
b. light from earth is reflected by the moon surface
Answer:
a= (2.3 m/s) / (3.0s) = 0.77 m/s2F= ma20.0 N = m (0.77 m/s2)m = 26 kgForce is measured with?Newtons (N) --> 1 N = 1 kg m/s2
