A 120 kg bike hits a tree while accelerating at 20 m/s2. What was it’s force as it hit the tree?

Given mass =120kg

acceleration =20m/s2

force =mass *acceleration =120*20=2400N

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.
