Answer:
60 V
Explanation:
From;
Vs/Vp = Ns/Np
Where;
Vs = voltage in the secondary coil = 6V
Vp = voltage in the primary coil= ??
Ns = number of turns in the secondary coil = 9
Np= number of turns in the primary coil = 90
6/Vp = 9/90
Vp= 90 * 6/9
Vp= 60 V
The answer is (2). Heat always flows down the temperature gradient, from high temperature to low temperature. Therefore, since the person is the warmest, heat flows from the person to both the ice and the air. Additionally, since the air is warmer than the ice, heat flows from the air to the ice.
Because metals that are more reactive than carbon wont react with it.
Redox Reaction is an ionic bond
Answer:: Ionic solutions completely dissociate into ions. i.e. NaCl becomes Na+ and Cl-.
Molecular compound donot dissociate, they remain whole compounds. i.e. CH2O remains CH2O.
