mihalych1998 [28]3 years ago
8 0

Answer:

o to increase the frequency of sound waves. It increases the sound waves to a level of frequency that humans cannot hear so you won't be able to hear many things though the wall other then low noises like pounding.

Explanation:

I am in construction class as well as a student teacher for other construction type programs trust me :D

Brainiest would be appreciated

Answer:

80⁰

Explanation:

triangle AOB = 180

So, a = 50

triangle CAB = a+a+x=180

CAB = 50+50+X=180

CAB = X = 180-100

X=80

QveST [7]

Answer:

A) motion parallax

Explanation:

Motion parallax is a visual perception while we are in motion with respect to our surrounding in which the surroundings objects nearer to our eyes appear to move or pass at a faster pace than the objects farther to our eyes during the motion.

This can also be understood as the angular displacement of the objects while our motion. The objects nearer to our eyes have a rapid change in the angular position than the objects far away from us.

By how much does the gravitational potential energy of a 55- kg pole vaulter change if her center of mass rises about 4.0 m duri
antiseptic1488 [7]

The change in the gravitational potential energy of the pole vaulter is 2,156 J.

<h3>Change in the gravitational potential energy </h3>

The change in the gravitational potential energy of the pole vaulter is calculated as follows;

ΔP.E = mg(Δh)

where;

  • m is mass
  • Δh is change in height

ΔP.E = (55)(9.8)(4)

ΔP.E = 2,156 J

Thus, the change in the gravitational potential energy of the pole vaulter is 2,156 J.

Transverse and longitudinal waves both
Anettt [7]
<h3><u>Answer</u>; </h3>

They both transfer energy through a medium in form of waves.

<h3><u>Explanation</u>;</h3>
  • Transverse waves are waves in which the waves move in perpendicular direction to the source of vibration of particles. For longitudinal waves, the waves move in parallel direction to the source of vibration.
  • <em><u>They are similar in the sense that energy is transferred in the form of waves. Therefore, they are common in that they both transfer energy through a medium.</u></em>
