Asmall 17 kilogram canoe is floating downriver at a speed of 3 m/s. what is the canoe's kinetic energy?

Kinetic energy = (1/2) · (mass) · (speed)²

A physics student on the river bank watching the canoe pass by

will say that it has 76.5 joules of kinetic energy, while another

student floating beside it in another boat will say that it has no

kinetic energy at all. Both students are correct.

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.
