Which statement is true for the hang time of a projectile? a) it can be calculated solely by knowing the horizontal component of the velocity. b) it can be calculated solely by knowing the vertical component of the velocity of projection. c) it can be calculated solely by knowing the resultant velocity of projection. d) it can be calculated solely by knowing the angle of projection.

i don’t know what the answer is i wish i

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.
