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:
A) from the lowest to the highest frequency:
Microwave - infrared - ultraviolet- X-ray
B) from the highest to the lowest energy:
X-ray - ultraviolet - infrared - microwave
Explanation: electromagnetic spectrum is the range of all types of electromagnetic radiation.
Radiation is the energy that travels and spreads out as it goes out.
The answer is 0k because 143c equals nothing
16.1=4.472222 i hope this helps!!
The frequency of the pendulum is independent of the mass on the end. (c)
This means that it doesn't matter if you hang a piece of spaghetti or a school bus from the bottom end. If there is no air resistance, and no friction at the top end, and the string has no mass, then the time it takes the pendulum to swing from one side to the other <u><em>only</em></u> depends on the <u><em>length</em></u> of the string.
