stuck on these 2 questions 1. A resistor made of Nichrome wire is used in an application where its resistance cannot change more than 2.53% from its value at 20.0°C. What is the highest temperature at which this resistor can be reliably used? The temperature coefficient of resistivity for Nichrome is 0.4 ✕ 10−3 (°C)−1. 2. An electronic device designed to operate at any temperature in the range from −9.9°C to 78.7°C contains pure carbon resistors. What is the percent...

10. -11 points SerPSE 10 26.4.OP.011. My Notes Ask Your Teacher A physics student is studying the effect of temperature on the resistance of a current carrying wire. She applies a voltage to a iron wire at a temperature of 53.0°C and notes that produces a current of 1.40 A. If she then applies the same voltage to the same wire at -88.0°C, what current should she expect (in A)? The temperature coefficient of resistivity for iron is 5.00 x...

My Notes Ask Your Tea points You have builtぁdevice that measures the temperature outside and displays it on dial as a measure of how far away from room temperature outside is. The way the dial works is that a needle with charged ball on the end is placed between two charged parallel plates. The strength of the uniform electric field between the plates is proportional to the outside temperature. Given that the charged ball on the needle has a charge...

A steel block of mass 6.4 kg is originally at a temperature of
18°C and 1 atm.
A steel block of mass 6.4 kg is originally at a temperature of 18°C and 1 atm. It is then heated to a temperature of 68°C without any change in pressure. The specific heat of steel is 452 J/(kg . °C), its density is 7.85 x 103 kq/m3, and the coefficient of linear expansion is 12 x 10-6/oc. (a) Determine the work done...
