A small object with mass 0.200 kg swings back and forth on the lower end of a light rope that is 3.00 m long. The upper end of the rope is attached to the ceiling. As the object swings through its lowest position, where the rope is vertical, the speed of the object is 8.50 m/s. At this point in the motion, what is the tension in the rope?

= 6.8 N

Explanation:

T = mg + ma

T = tension, N

m = mass, kg

g = gravitational force, 9.8 m/s2²

a = acceleration, m/s²

a =( 8.5²) / 3

a = 24.08

T = mg + ma

T = m (g + a)

T = 0.2 ( 9.8 + 24.08)

T = 0.2 ( 33.88)

T = 6.776N

≅ 6.8N

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.
