First it's spelled ancient and their.
More importantly, the answers:
Ancient Greeks would perform in theatre, but normally only during festivals and each play would only be performed once.
School wasn't mandatory, but most children still went.
Hope this helped!
Answer:
L= 0.4 kgm²/s
Explanation:
The angular momentum of a hallow spinning sphere is
L = Iω
L = (0.02kgm²) × (20rad/s)
L= 0.4kgm²/s
Acceleration is the rate of change in an object's velocity
The statements that correctly compare the gravitational force with the electrical force are the following:
-The gravitational force can be attractive.
-The electrical force can be repulsive.
-The electrical force can be attractive.
-Any two objects experience a gravitational force between them.
Answer:
The peak emf of the generator is 40.94 V.
Explanation:
Given that,
Number of turns in primary coil= 11
Number of turns in secondary coil= 18
Peak voltage = 67 V
We nee to calculate the peak emf
Using relation of number of turns and emf
Where, N₁ = Number of turns in primary coil
N₂ = Number of turns in secondary coil
E₂ = emf across secondary coil
Put the value into the formula
Hence, The peak emf of the generator is 40.94 V.
