The shape of a projectiles trajectory is called an ellipse

ANSWER:

The shape of a projectiles trajectory is not called an ellipse,it is parabolic.

EXPLANATION:

Projectile motion is a kind of motion where an object moves in a bilaterally well-formed, parabolic path. The path that the object follows is called its trajectory. Projectile motion only occurs when there is one force implemented at the start on the trajectory, after which the only restraint is, from the gravity.When we look at the shape of trajectory it forms a parabolic shape as discussed above.

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.
