Boat A and boat B have the same mass. BoatA’s velocity is three times greater than that of boat B. Compared to the kinetic energy of boat B, the kinetic energy of boat A is?

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.

more than, less

less than, more

because if the tool that you are using is not balanced it there would be false mass.
