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
Answer:
the total travled is 2.75
Explanation:
because if you divide 110 by 40 you get 2.75
Answer:
alpha=53.56rad/s
a=5784rad/s^2
Explanation:
First of all, we have to compute the time in which point D has a velocity of v=23ft/s (v0=0ft/s)
Now, we can calculate the angular acceleration (w0=0rad/s)
with this value we can compute the angular velocity
and the tangential velocity of point B, and then the acceleration of point B:

Answer:
The Nucleus
Explanation:
The nucleus contains the majority of an atom's mass because protons and neutrons are much heavier than electrons, whereas electrons occupy almost all of an atom's volume. I hope this helps you :D
Answer:
Technician B
Explanation:
This can be explained as a fuse is a protective device which blows in order to protect the circuit and the equipment from short circuiting.
Short circuit is a condition where a very heavy current flow through the line with no low line impedance which is not the intended path for the current to flow.
Thus when heavy current flows through a fuse it blows out thus disconnecting the path for the current flow.
Therefore, if a fuse burns out when switch is on, short circuit is present after the switch
