Answer:
The fundamental frequency and the length of the pipe are 115.8 Hz and 1.48 m.
Explanation:
Given that,
First frequency = 986 Hz
Second frequency = 1102 Hz
We need to calculate the length of the pipe
Using formula of length
Put the value into the formula
We need to calculate the fundamental frequency of this pipe
Put the value into the formula
Hence, The fundamental frequency and the length of the pipe are 115.8 Hz and 1.48 m.
Answer:
50000 μT
Explanation:
From the given information:
the diameter of the loop = 1.0 mm = 0.001 m
no of turns (N) = 200
current (I) = 0.199 A
radius = d/2 = 0.001/2
= 5 × 10⁻⁴ m
Recall that;
the magnetic field at the centre of circular wire is:
= 0.05 T
= 50000 μT
Since the centre of the earth's magnetic field is given to be equal to the magnetic field produced by the wire, then:
the earth's magnetic field = 50000 μT
You just identified the image as a "reflection", so it's a pretty good bet that
the phenomenon involves reflection somehow.
Your dog can see his reflection in a mirror inside the house just as easily
as in the surface of the pond. My dogs do it all the time. The phenomenon
doesn't require water.
It's reflection of light waves.
I think its C. because metal is a good conductor of heat
I hope this helps ^-^
let me know if im wrong
The message is the information being communicated from one place to another.
It used to be called the "intelligence". But as time went on, it became
harder to ignore the obvious fact that that was going too far, and the
label was changed to the more IQ-neutral "message".
