(Triple points) A scientist found that a sample of metal expands from 26.1 cm3 to 26.2 cm3 when heated from 25 °C to 75 °C. What would the coefficient of volume expansion be for this metal?

The magnitude of the magnetic field at a certain distance from a long, straight conductor is represented by b. what is the magnitude of the magnetic field at twice the distance from the conductor? a. at twice the distance, the magnitude of the field is 4b.b. at twice the distance, the magnitude of the field is 2b.c. at twice the distance, the magnitude of the field is b/2.d. at twice the distance, the magnitude of the field is b/4.e. at twice the distance, the magnitude of the field remains equal to b.
