In a television set the power needed to operate the picture tubecomes from the secondary of a transformer. The primary of thetransformer is connected to a 120-V receptacle on a wall. Thepicture tube of the television set uses 89W, and there is 5.5 mA of current in the secondary coil of thetransformer to which the tube is connected. Find the turns ratioNs/Np of thetransformer. Ns/Np =

answer: 2×10^-2kg

explanation: density= mass per volume

vol=mass/density

converting to s.i units we have;

3÷1000kg = 0.003

1.5÷100m = 0.15

0.003/0.15 = 0.02kg
