Answer:
Part a)
ZERO
Part b)
N = 10 turns
Explanation:
Part a)
As we know that transformer is used to change the input voltage into required output voltage
Here this input and output is considered only when it will change with time as the whole concept is based upon Faraday's law where we need to change the flux with time.
So if we have input Source is DC source then output voltage will be zero as there is no flux change
Part b)
As we know by the principle of transformer
![\frac{V_1}{V_2} = \frac{N_1}{N_2}](https://tex.z-dn.net/?f=%5Cfrac%7BV_1%7D%7BV_2%7D%20%3D%20%5Cfrac%7BN_1%7D%7BN_2%7D)
![\frac{500}{25} = \frac{200}{N_2}](https://tex.z-dn.net/?f=%5Cfrac%7B500%7D%7B25%7D%20%3D%20%5Cfrac%7B200%7D%7BN_2%7D)
![N_2 = 10](https://tex.z-dn.net/?f=N_2%20%3D%2010)
so total number of turns in secondary coil must be 10
Answer:
The answer is "
".
Explanation:
Using formula for calculating the Voltage:
![M_1=12.5\\\\M_2=250\\\\V_1=4,500 \\\\\bold{\text{Formula: }}\\\\\to \bold{\frac{m_1}{m_2}=\frac{V_2}{V_1}}\\\\\to \frac{12.5}{250}=\frac{V_2}{4,500}\\\\\to 0.05=\frac{v_2}{4,500}\\\\\to 0.05\times 4,500= V_2\\\\\to V_2=225\\\\](https://tex.z-dn.net/?f=M_1%3D12.5%5C%5C%5C%5CM_2%3D250%5C%5C%5C%5CV_1%3D4%2C500%20%5C%5C%5C%5C%5Cbold%7B%5Ctext%7BFormula%3A%20%7D%7D%5C%5C%5C%5C%5Cto%20%5Cbold%7B%5Cfrac%7Bm_1%7D%7Bm_2%7D%3D%5Cfrac%7BV_2%7D%7BV_1%7D%7D%5C%5C%5C%5C%5Cto%20%5Cfrac%7B12.5%7D%7B250%7D%3D%5Cfrac%7BV_2%7D%7B4%2C500%7D%5C%5C%5C%5C%5Cto%200.05%3D%5Cfrac%7Bv_2%7D%7B4%2C500%7D%5C%5C%5C%5C%5Cto%200.05%5Ctimes%204%2C500%3D%20V_2%5C%5C%5C%5C%5Cto%20V_2%3D225%5C%5C%5C%5C)
Hence the range of accelerating in voltage is ![4,500 - 225 \ V](https://tex.z-dn.net/?f=4%2C500%20-%20225%20%5C%20V)
Answer:
Distance covered is: 45 meters
Displacement is 15 meters to the right of where he started
Explanation:
Notice that Brady has walk a path that looks like an incomplete rectangle of height 5 meters and length 25meters, although he actually didn't cover the full length (25 meters) when getting back to the point where he started (he made just 10 meters instead of 25 after the third turn right) See attached image.
Therefore, Brady's displacement is 15 meters to the right of where he started, and the total distance he covered is :
Distance = 5m + 25m + 5m + 10m = 45m
