alexgriva [62]

Answer:

Number of turns on the secondary coil of the adapter transformer is 10.

Explanation:

For a transformer,

    \frac{V_{s} }{V_{p} } = \frac{N_{s} }{N_{p} }

where V_{s} is the voltage induced in the secondary coil

           V_{p} is the voltage in the primary coil

          N_{s} is the number of turns of secondary coil

         N_{p} is the number of turns of primary coil

From the given question,

    \frac{487*10^{-3} }{120} = \frac{N_{s} }{2464}

⇒    N_{s} = \frac{2462*487*10^{-3} }{120}

            = 9.999733

  ∴   N_{s} = 10 turns

A sample of ice at 0°C has a mass of 23 g and a volume of 25 cm^3. Why does ice float on water? The density of water is 1 g.
vlabodo [156]

Answer: ice float in water due to density differences. Water has a higher density than ice.less dense object in liquid with high density

Explanation: from density formulae.

D=M/V

Density of ice =Mass of ice/Volume of ice

D=23/25

D=0.92g/cm^3

a kid is on a skate board going 14kph and trows a set of keys on the ground at 8kph. the spped of the keys relitive to the gound
Vanyuwa [196]
To determine the speed relative to the ground, since the ground is our reference frame, it would be v = 0, for the kid on the skateboard, you would need to take into account the speed that he/she is going and the speed of the keys thrown at.

I believe.
