A copper wire having a resistance of 5 ohm is connected in series with an aluminium wire having a resistance of 10 ohm at 0°c find the resistance combination at 30°C given that temperature coefficient is
4.3x10 -2/ °C for copper and 3.9x10-3/0c for aluminum​

answer would be letter choice (a),   a ball resting on a shelf. would be another example of potential energy   >   stored energy > not moving.

a ball spinning on a finger   >   kinetic energy > moving energy

a ball rolling on the ground   >   kinetic energy   > moving energy

a   ball flying through the air   > kinetic energy   >   moving energy

hope that                                         : )

the right answer is 0.3 meters per second
