Answer:
Explanation:
Given:
Length of the parallel wires (L) = 3.7 m
Current in the first wire (I₁) = 3.6 A
Current in the second wire (I₂) = 1.6 A
Separation between the parallel wires (d) = 3.1 cm = 0.031 m [1 cm = 0.01 m]
Both the wires will attract each with forces equal in magnitude and opposite in direction.
Now, the magnitude of the force acting between the two wires is given as:
Where,
Plug in the given values and solve for |F|. This gives,
Therefore, the magnitude of the force between the two wires is
Answer: 6.65 rad/s
Explanation:
Firstly, we need to know that according the kinetic theory of gases, the average kinetic energy of a molecule with degrees of freedom is:
(1)
Where:
because oxigen is a diatomic molecule and has 5 degrees of freedom
is the Boltzman constant
is the temperature
Then:
(2)
(3) With this value of average kinetic energy we can find the average angular velocity, with the following equation:
(4)
Where:
is the moment of inertia
is the angular velocity
Now, (5)
Being the molar mass of Oxigen molecule and the distance between atoms
(6)
(7)
Substituting (7) and (3) in (4):
(8)
Finding :
(9) This is the average angular velocity for a molecule of O2
By loud noise, mostly from concerts.
Answer:
0.2m
The solution is in the picture
Answer:
8
Explanation:
(8√2)² = x² + x²
8² × √2² = 2x²
64 × 2 = 2x²
128 = 2x²
64 = x²
x = 8
