To solve the problem, we need to find the temperature at which the resistance of a platinum wire increases by 10% from its value at 10°C. We will use the formula for resistance change based on the temperature coefficient of resistance. ### Step-by-Step Solution: 1. **Understand the Initial Conditions**: - Let the resistance at 10°C be \( R_1 \). - The resistance increases by 10%, so the new resistance \( R_2 \) can be expressed as: \[ ...
