A solid cylinder of mass 7 kg and radius 0.9 m starts from rest at the top of a 20º incline. It is released and rolls without sl
ohaa [14]

Answer:

157.8 J

Explanation:

m = mass of the cylinder = 7 kg

h = height difference in top and bottom of the incline = 2.3 m

g = acceleration due to gravity = 9.8 m/s²

TE = Total Energy at the bottom

PE = Gravitational potential energy at the top

Using conservation of energy

Total Energy at the bottom = Gravitational potential energy at the top  

TE = PE

TE = m g h

TE = (7) (9.8) (2.3)

TE = 157.8 J

When the sound from two sound waves goes up and down (loud, soft, loud, soft) it makes a distinctive sound pattern called beats.
djverab [1.8K]

The beats are actually two new sounds.

Their frequencies are (the sum of the original two frequencies) and (the difference of the original two frequencies).

The existence of the beats is the result of the difference in the frequencies of the original two sounds. <em> (b)</em>
