Answer:
Plutonium, has formula Pu with molecular mass 94
Explanation:
Answer:
the answer is B
Explanation:
we assume that all of these springs have tha same k , the spring constant
elastic energy for the initial system = Ep1=
for the new changed system , the spring constant = k1+k2 = k+k = 2k , but the displacement is also reduced to 0.5 d
so Ep2 =
so the new total Ep stored in the new system is 1/2Ep

Answer:
Viscosity of the fluid is
Explanation:
Given
- Length of the concentric cylinders, L=75 cm
- Gap between two concentric cylinders = 1 mm
- The frequency of inner cylinder = 300 rpm
- Torque acting
- Outer diameter of the inner cylinder=15 cm
The Area is given by
The velocity of the layer is layer is given by
Force acting by one layer of the fluid to other is given by F
Now from the Law of viscosity we have
Hence the viscosity of the fluid is
<span>That statement is false. An upward fold on a rock is acalled an anticline
a typical anticline is convex up in which the hinge or crest is located where the curvature is the greatest and the limbs are the side of the fold that dip away from the hinge</span>
