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).

Vlad1618 [11]

Answer:

They are the same (assuming there is no air friction)

Explanation:

Take a look at the picture.

When the first ball (the one thrown upward) gets to the point marked as A, the speed will has the exact same value V but the velocity will now point downward (just like the second ball).

So if you think about it, the first ball, from point A to the ground, will behave exactly like the second ball (same initial speed, same height).

That is why the speeds will be the same when they reach the ground.

How do you think the amount of a material affects its tendency to sink or float?
Viktor [21]

Answer:

Things float when they are positively buoyant, or less dense than the fluid in which they are sitting. This does not mean that an object has to be lighter than the fluid, as in the case of a boat; objects just need to have a greater ratio of empty space to mass than the fluid.

A student on an amusement park ride moves in a circular path with a radius of 3.5 meters once every 8.9 seconds. What is the ave
Ulleksa [173]
Distance traveled by him = circumference of that circular path = 2πr = 2π(3.5)
= 7π = 7×3.14 = 21.98 m
time = 8.9 s  [ Given ]

Now, Average speed = distance / time
s = 21.98 / 8.9
s = 2.46 m/s

Hope this helps!
