Answer:
Explanation:
Given:
- dimension of square plate,
- thickness of fluid layer,
- force on the fluid due to plate,
- velocity of plate,
<u>Using Newton's law of viscosity:</u>
..........................................(1)
where:
shear force on the surface on the fluid
coefficient of (dynamic) viscosity
Now, shear force:
Putting respective values in eq.(1)
Answer:T=1316.21 N
Explanation:
The tension has two components: Vertical and Horizontal. The
horizontal component is ma, the vertical component is mg. Using
Pythagoras theorem, we can find the tension as:
T=((ma)^2 (mg)^2)^(1/2)
So
T=((129*2.84)^2 (129*9.8)^2)^(1/2)
T=1316.21 N
a.the amount of sunlight increases.
Explanation:
As a submarine rises to the surface, the change it encounters that is true from the given options is that the amount of sunlight increases.
The bottom of the ocean is dark and receives little to no sunlight due to the scattering of the rays by ocean water.
- As the submarine rises, the volume of water column on it decreases and the pressure on it decreases too.
- Also, the temperature rises steadily to the surface.
