The speed of a 16cm wave with a period of 8 seconds is 2cm/s
<h3>How to determine the speed</h3>
Using the formula;
Speed = distance ÷ time
Distance = 16cm
time = 8 seconds
Substitute into the formula
Speed = 16 ÷ 8
Speed = 2 cm/s
Therefore, the speed of a 16cm wave with a period of 8 seconds is 2cm/s

Given that,
mass m= 5.7 kg
Force of gravity = ?
Since,
Force of gravity acting on earth is equal to the weight and
W= mg
W= 5.7 * 9.81
W= 55.917
or
W= 56 N
Force of gravity acting on Earth by the package is 56 N.
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!!
