Answer:
A: greater than the volume of object B
Explanation:
Based on the dimensions, the volume of object A is ...
(3 cm)(2 cm)(4 cm) = 24 cm³ = 24 mL
If object B displaces 19 mL of water, we presume that is its volume. Since 24 mL is more than 19 mL, we conclude ...
The volume of object A is greater than the volume of object B.
_____
<em>Comment on density</em>
We have presumed that object B is completely submerged. If it is not, then the relative volumes will depend on the densities. If the density of object B is less than about (19/24) g/mL, its volume may very well be larger than that of object A.
Answer:
the minimum thickness (in nm) t = 102.5 nm
Explanation:
t = thickness of the film
n = index of refraction = 1.61
m = order = 1
∝ = wavelength = 330 x 10-9 m
so we have the formula
2nt = m∝
2 (1.61) t = (1) (330 x 10-9)
then...
t = 1.025 x 10-7 m
converting...
t = 102.5 nm

F=ma which is newtons second law. so we have here a=g in this situation and g=gravity and that equals 9.80m/s^2 on earth surface. So we have F=5.7kg*9.80m/s^2=55.9N or Newtons. Thank You! Please rate!
