Volume by Displacement. The displacement method (submersion, or dunking method) can be used to accurately measure the volume of the human body and other oddly shaped objects by measuring the volume of fluid displaced when the object is submerged.
The following precautions should be taken very observantly:-
The line of sight must be perpendicular to measuring scale to avoid parallax error. Formation of bubbles inside the cylinder should be completely avoided. Any bubbles within leads to wrong measurements.
Answer:
False
Explanation:
The net force is equal to the applied force minus the force of friction. It is possible for friction to act in the same direction as an applied force, but that would mean there would have to be more than two forces acting on the object.
Answer:
VL=2107.6v
Explanation:
at resonance xc=xL
1/wc = wL
z=R
because sqr(R^2+(xL-xc))
^
(xL=xc)
V/R=I
90/28.9=3.1142A
w=1/sqr(1.31×(2.86×10^-6))=516.63
xL= wL
xL= 516.63×1.31=676.785
VL=3.1142×676.785
VL=2107.6v
