Answer:

As far as i know, it's when the nerves at the top of your mouth (or the roof) sense the cold.

Explanation:

This is different to you sensing cold in your fingers or other parts of your body as it is closer to the roof of your mouth making your nerve feel much more. Since those nerves are exposed to that cold so much more than most other parts (and are closer to the brain, which i'm not sure if it affects anything) you feel a freeze which most people think they feel at their brain, hence the name 'Brain freeze'

Hope it helps!

Answer:

The answer is 6.4 × 10^{-20} Joules

Explanation:

This question wants to effectively test your knowledge of the names of the negative powers of 10, so first of all, before calculating, let me explain what each of the symbols in the units given in the question means:

Force = 8.0 pN = 8.0 × 10^{-12} N

displacement = 8.0 nm = 8.0 × 10^{-9} N

Now let us calculate the work.

work = Force × Displacement

work = 8.0 × 10^{-12}  × 8.0 × 10^{-9} = 64 × 10^{-21}

= 6.4 × 10^{20} Joules (in standard form)

Explain how and why the walls of the ventricles differ in thickness.<br> and between
baherus [9]

Answer:

The ventricles of the heart have thicker muscular walls than the atria. This is because blood is pumped out of the heart at greater pressure from these chambers compared to the atria. ... This is due to the higher forces needed to pump blood through the systemic circuit (around the body) compared to the pulmonary circuit.

Under which condition would a body of rock be most likely to exhibit brittle behavior?
torisob [31]
A body of rock would most likely exhibit brittle behavior under the condition of LOW TEMPERATURE.
At low temperature, the water in the crevices of the rock will freeze up, the freezing up of this water causes fractures in the rocks  and as time goes on the rocks become brittle and parts of it will start falling away.<span />
