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)
The type of energy that a spinning turbine has is called mechanical energy. When an objects kinetic energy is added to the objects potential energy is makes mechanical energy. The correct answer is D.
Answer:
The transverse displacement is 
Explanation:
From the question we are told that
The generally equation for the mechanical wave is
The speed of the transverse wave is 
The amplitude of the transverse wave is 
The wavelength of the transverse wave is 
At t= 0.150s , x = 1.51 m
The angular frequency of the wave is mathematically represented as
Substituting values
The propagation constant k is mathematically represented as
Substituting values
Substituting values into the equation for mechanical waves
Answer:
Explanation:
The amount of force needed needs to be greater than all the forces acting in the opposite direction that the bowling ball was thrown. This includes air resistance, floor friction, gravity, and any other force involved. As long as the force acting on the bowling ball that is causing it to go in the direction of the pins is slightly greater than the opposite acting forces then it will continue in that direction. Since no values are provided we cannot calculate the actual precise value of force needed.
We Know, K.E. = 1/2 × m × v²
From the expression, we can conclude that Kinetic energy is directly proportional to mass. So, as mass will increase, Kinetic energy will also increase.
In short, Your Correct answer would be Option B
Hope this helps!
