Answer:
<em>The non resonance frequency of the generator is = 1201.79 Hz</em>
Explanation:
At resonance,
f₀ = 1/2π√LC..................... Equation 1
Where f₀ = resonance frequency, L = inductance, C = capacitance
making LC the subject of the equation
LC = 1/4πf₀²..................... Equation 2
<em>Given: </em>f₀ = 225 Hz, and π = 3.143
<em>Substituting these values into equation 2,</em>
LC = 1/(4×3.143²×225²)
LC = 1/2000385.9
LC = 5×10⁻⁷
If the ratio of capacitive reactance to inductive reactance = 5.36
1/2πfC/2πfL = 5.36
1/4π²f²LC = 5.36
Where f = frequency of the non resonant
making f the subject of the equation
f = 5.36/2π√LC ............. Equation 3
Substituting the value of LC = 5×10⁻⁷ into equation 3
f = 5.36/2×3.143√(5×10⁻⁷)
f = 5.36/(6.286×0.00071)
f = 5.36/0.00446
<em>f = 1201.79 Hz</em>
<em>Thus the non resonant frequency of the generator is = 1201.79 Hz</em>
Current is measured as charge per unit time. To get change, simply multiply the current with time:
Russia and the United States sign the Moscow Treaty.
Answer:
Chemical energy to electrical energy to mechanical and thermal energy
Explanation:
In the rotating fan, the chemical energy stored in the battery is used to generate electrical energy.
The electrolytes within the battery undergoes chemical reactions that produces electric current.
- The current is being used to drive the motor of the fan to produce a mechanical energy as it rotates.
- In like manner, heat energy is also produced.
- So, energy is simply being transformed from one form to the other in this system.
Answer:d
Explanation:
Given
First car is moving towards east with velocity 20 m/s
then it turns towards north then velocity is
suppose car takes t sec to change its path so average acceleration is given by
So average acceleration is towards North of west.
