Use the graph to answer the question. if the runner continues at the same speed, how far the runner travel in 30 seconds?

120 Meters

Explanation:

10(time)=40(distance)

40 x 3=120

real, smaller and upside-down.   so the answer should be b.

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.
