An object weighing 4 newtons swings on the end of a string as a simple pendulum. at the bottom of the swing, the tension in the string is 6 newtons. what is the magnitude of the centripetal acceleration of the object at the bottom of the swing?

0.5g or 4.905 m/s²

Explanation:

= Tension =

= Centripetal acceleration

g = Acceleration due to gravity = 9.81 m/s²

In this system the forces are conserved

The magnitude of the centripetal acceleration of the object at the bottom of the swing is 0.5g or 4.905 m/s²

.) the observation by semmelweis that more mothers died of childbed fever when their doctors also worked in the morgue

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.
