Your answer would be D. Mechanical and Pressure/Longitudinal. This is because a sound wave is usually a type of pressure wave caused by the vibration of an object in a conductive medium such as air. These waves are also mechanical because they require a medium to travel through. This is also why sound simply cannot travel through vacuums like space, because they have no mediums in which sound can travel through.

Carla is babysitting her 2-year-old nephew for the first time. While her back is turned just for a moment, he touches the pan sh
defon

Answer:

Screaming is an emotional response triggered by the brain which receives information about the pain later as compared to pulling away of finger which is a reflex action facilitated by the spinal cord that has a quicker-time to response.

Explanation:

Reflex action happens when part of our body comes to contact with an object which can cause harm and you tend to quickly withdraw that part of the body.Reflex action happens quicker before the brain gets the time to process information about the harm.

When the baby touched the hot pan, at point of contact, skin receptors send nerve impulses to the spinal cord. Interneurons in the spinal cord relay a response to motor neurons to stimulate muscle contraction making the baby to pull his finger away.This happens so fast before the brain receives the message later to trigger emotional response(screaming).

1. A silicon BJT is connected as shown in Fig 1, where RC = 3.6 k 2. VBE = 0.8 V. (10%)
Masja [62]

Answer:

The circuit is missing attached below is the required circuit

answer :

a) Ic = 1.944 mA

  Rp = 288.66 kΩ

b) <em>The Emitter-base Junction of the BJT is forward biased while its collector-base junction is reverse biased</em>

Explanation:

Rc = 3.6 kΩ

VBE = 0.8 v

<u>1) predict Ic and specify Rp to establish Vce at 5 V </u>

we will apply Kirchhoff's voltage law to resolve this

solution attached below

b ) The BJT is said to be in Forward reverse bias because <em>The Emitter-base Junction of the BJT is forward biased while its collector-base junction is reverse biased</em>
