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
Just because there is more mass in a certain substance doesn’t mean it’s density will change. In this case, water, will not change density simply because there is more of it. I.e the ocean. The bottom of the ocean may have more pressure to it because of the weight of the water above it but if you were to take a cup of it and take it to the surface it wouldn’t sink.
1. Friction (Example: when you rub your hands together and you start to feel heat.)
2. Attract each other. (Example: Every object has a gravitational pull of some sort. The larger the object, the stronger the gravitational pull. This is why the sun is able to keep all eight planets in orbit around it.)
3. Hope this helped :)
The moon rises in the east & rises in the west I believe, it also rotates Clockwise I think.
That's "electromagnetic" energy. It also includes radio, heat, light, and X-rays.
