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
![\dfrac{N_{1}}{N_{2}}=\dfrac{E_{1}}{E_{2}}](https://tex.z-dn.net/?f=%5Cdfrac%7BN_%7B1%7D%7D%7BN_%7B2%7D%7D%3D%5Cdfrac%7BE_%7B1%7D%7D%7BE_%7B2%7D%7D)
![E_{1}=\dfrac{N_{1}}{N_{2}}\times E_{2}](https://tex.z-dn.net/?f=E_%7B1%7D%3D%5Cdfrac%7BN_%7B1%7D%7D%7BN_%7B2%7D%7D%5Ctimes%20E_%7B2%7D)
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
![E_{1}=\dfrac{11}{18}\times67](https://tex.z-dn.net/?f=E_%7B1%7D%3D%5Cdfrac%7B11%7D%7B18%7D%5Ctimes67)
![E_{1}=40.94\ V](https://tex.z-dn.net/?f=E_%7B1%7D%3D40.94%5C%20V)
Hence, The peak emf of the generator is 40.94 V.
Answer:
The two objects are traveling at the same speed.
Explanation:
Neglecting air resistance, an object that is thrown up from the top of a tall building has the same speed as the second object thrown down from the top of the same tall building since the initial speed is the same.
The object thrown up is not traveling faster neither is the object thrown down traveling faster.
Therefore, the two objects will have the same speed when they hit the ground but their time of landing might be different.
Answer:
C
Explanation:
When A and B come in contact with each other, +12 - 12 = 0 so their changes cancel.
Now C has a charge of +12
When A and C come together they each have an equal share of that 12, so each of them has 6
So the answer is
A B C
6 0 6
which is C
I think that mechanism is called a <em>"lens turret"</em>.
