Answer:

Explanation:

I'm assuming your charge is in Coulombs so I will proceed that way. The formula for this electric field problem is

E=\frac{kQ}{r^2} where k = 9.0 × 10⁹. Filling in:

E=\frac{(9.0*10^9)(1.25*10^{-3})}{.4^2} gives us an electric field value of

7.0 × 10⁷ N/C

The 400-turn primary coil of a step-down transformer is connected to an ac line that is 120 V rms. The secondary coil voltage is
KengaRu [80]

Explanation:

The given data is as follows.

             V_{1} = 120 V,    V_{2} = 6.50 V

             N_{1} = 400,     N_{2} = ?

Formula to calculate the number of turns in secondary coil are as follows.

          \frac{N_{1}}{N_{2}} = \frac{V_{1}}{V_{2}}

Putting the given values into the above formula as follows.

         \frac{N_{1}}{N_{2}} = \frac{V_{1}}{V_{2}}

        \frac{400}{N_{2}} = \frac{120}{6.50}

              N_{2} = 21.66

                          = 22 (approx)

Thus, we can conclude that number of turns in the secondary coil are 22.

fenix001 [56]

Answer:

2400 cm

Explanation:

The milky way has diameter of 100000 light years.

100000\ ly=24\ cm\\\Rightarrow 1\ ly=\frac{24}{100000}\ cm

The local group is the collection of galaxies which includes the milky way.

10 million light years is the diameter of the local group.

10\times 10^6\ ly=10\times 10^6\times \frac{24}{100000}\ cm\\\Rightarrow 10\times 10^6\ ly=2400\ cm

Hence, the diameter of the scale model of the local group would be 2400 cm
