Water has a specific heat of 4.184
J/Kg°C. Wood has a specific heat
of 1.760 J/Kg°C. What material
needs more energy to raise the
temperature 1°C
.

Water needs more energy to raise temperature by 1°C

Explanation:

Specific heat energy is the energy needed for a material to raise its temperature by a degree. A material with higher specific heat energy needs more energy and a material with lower specific heat energy needs less energy.

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.

i think the answer is a and b

i wish you luck
