Which of the following is accurate when discussing specific heat? Question 9 options: A) The specific heat of a gas can be measured at constant pressure. B) Specific heat values for solids will never vary for different ranges of temperature. C) The specific heat of a gas can be measured at constant volume only. D) Specific heat values for liquids will never vary for different ranges of temperature.

adding a(n) to an electric circuit would increase the magnetic field around a wire;

b. solenoid

a solenoid is a type of electromagnet whose purpose is to generate a controlled magnetic field.

if the purpose of the solenoid is instead to impede changes in the electric current, a solenoid can be more specifically classified as an inductor rather than an electromagnet.

layers of the earth affect the waves and these effects are seen on instruiments such as seimometers

when heated, the valance electrons increased their speed and transferred the heat from electron to electron.   i just took the test.
