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).
None of the above since gravity pulls objects toward each other.
Answer:
P = 30000 [kg*m/s]
Explanation:
Momentum in physics is defined as the product of force in the given time interval. In this way, it can be expressed by means of the following equation.
where:
P = momentum [kg*m/s]
F = force = 6*10⁴ [N]
t = 0.5 [s]
Now replacing:
![P=6*10^{4}*0.5\\P=30000[kg*m/s]](https://tex.z-dn.net/?f=P%3D6%2A10%5E%7B4%7D%2A0.5%5C%5CP%3D30000%5Bkg%2Am%2Fs%5D)
Answer:
Homogeneous mixtures may be solids, liquids, or gases. Examples include steel, wine, and air. A homogeneous mixture is a solid, liquid, or gaseous mixture that has a uniform composition. No matter where you sample the mixture, the amount and type of components is the same.
