Answer:
C: Variation in the value of g as the pendulum bob moves along its arc.
Explanation:
The formula for period of a simple pendulum is given by;
T = 2π√(L/g)
Where;
L is length
g is acceleration due to gravity
Now, from this period equation, it is clear that the only thing that can affect the period of a simple pendulum are changes to its length and acceleration due to gravity.
Looking at the options, the only one that talks about either the length or gravity as being potential causes of the error is option C
Answer:
you cant caculate this because there is no question
Explanation:
It depends, How big is the room. If it was me i would put "High density foam pads" all over the walls in the room, and that would get rid of some sound but put Drywall, or Plasterboard behind the foam pads. That should hopefully get rid of the sound from outside the room, and stop any noise in the background, if your using a mic, for example, a Youtube channel, or Twitch treaming channel. Hope this helps. BYE!!
