3. A body is fired up a smooth inclined plan with a velocity of 8.0 m/s. If the plane is inclined at 30° to the horizontal, calculate the distance covered and the time taken (g = 10 m/s2). [A] 3.14 m, 1.05 sec [B] 64.00 m, 5.00 sec (C) 6.40 m,
1.60 sec (D) 12.80 m, 10.00 sec​

d. learned preferences i believe is your answer

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.

close lines strong magnet less close weaker

connect the batteries in series and hope
