Answer:
150.8 J
Explanation:
The heat released by the copper wire is given by:

where:
m = 10.0 g is the mass of the wire
Cs = 0.377 j/(g.C) is the specific heat capacity of copper
is the change in temperature of the wire
Substituting into the equation, we find

And the sign is negative because the heat is released by the wire.
I think shock waves require more speed they travel at the speed of sound
I think the answer A since temperature is the average kinetic energy of the molecules, so increasing temperature must increase kinetic energy
