Answer:
The current in the second wire is 8.33 A and the two currents are flowing in the opposite directions
Explanation:
Given that,
The separation between two long parallel wires, d = 2.5 cm
The force per unit length that each wire exerts on the other is, 
The current in one wire, 
(a) The force per unit length of the wire is given by :
On putting all the values we get :
So, the current in the second wire is 8.33 A.
(b) It is given that, both the wires repel each other, so the current in other wire is flowing in the opposite direction of the current in the first wire.
Hence, this is the required solution.
Answer:
Our final answer is option (c) that is :
A resonant mode of your vocal tract.
Explanation:
Lets understand pitch of a sound first:
Pitch: Is the rate of vibrations produced and also the degree of lowness and highness of a tone.
Pitch formant:
When we take air inside our vocal tract it oscillates at different pitches depending upon the cast and capacity of the opening of the vocal tract.
Formant comes from the vocal tract and also at a resonance of our vocal tract.
So basically the vocal tract play a vital role for the formant.
Final answer is : A formant is a resonant mode of our vocal tract.
Answer:
Explanation:
We shall find the volume of stored gas at atmospheric pressure .
P₁ V₁ = P₂ V₂
15.5 x 10⁶ x .02 = 10⁵ x V₂ ( atmospheric pressure is 10⁵ Pa )
V₂ = 3.1 m³
volume of one balloon = 4/3 x π r³ , r is radius of balloon
= 4/3 π x .11³
= .050658 m³
no of balloon = total volume to be filled / volume of one balloon
= 3.1 / .050658
= 61 .2
= 61
