Answer: Hi!
A neuron is a basic working unit of the brain. Neurons are special cells designed to transfer information to other nerve, muscle, or gland cells. They are pretty cool - looking too! (A slightly irregular circular shape with branches reaching out from all sides.) A neuron is a nerve cell. Nerve cells are the way of communication in the nervous system.
Hope this helps!
Answer:
0.37 m
Explanation:
Given :
Window height, 
= 1.27 m
The flowerpot falls 0.84 m off the window height, i.e.
= (1.27 x 0.84 ) m in a time span of 
seconds.
Assuming that the speed of the pot just above the window is v then,
![$v=\left(\frac{30}{8}\right) \left[ (1.27 \times 0.84) - \left( \frac{1}{2} \times 9.81 \times \left( \frac{8}{30 \right)^2 \right) \right]}$](https://tex.z-dn.net/?f=%24v%3D%5Cleft%28%5Cfrac%7B30%7D%7B8%7D%5Cright%29%20%5Cleft%5B%20%281.27%20%5Ctimes%200.84%29%20-%20%5Cleft%28%20%5Cfrac%7B1%7D%7B2%7D%20%5Ctimes%209.81%20%5Ctimes%20%5Cleft%28%20%5Cfrac%7B8%7D%7B30%20%5Cright%29%5E2%20%5Cright%29%20%5Cright%5D%7D%24)
m/s
Initially the pot was dropped from rest. So, u = 0.
If it has fallen from a height of h above the window then,
h = 0.37 m
<span>A rocket in its simplest form is a chamber enclosing a gas under pressure. A small opening at one end of the chamber allows the gas to escape, and in doing so provides a thrust that propels the rocket in the opposite direction. A good example of this is a balloon. Air inside a balloon is compressed by the balloon's rubber walls. The air pushes back so that the inward and outward pressing forces are balanced. When the nozzle is released, air escapes through it and the balloon is propelled in the opposite direction.</span>
For this problem, we would be using the formula: Vf^2 = Vi^2 + 2ad
where:
Vf = 400m/s
Vi = 300m/s
a = ?
d = 4.0km
= 4000m
400^2 = 300^2 + 2a4000
a = [ 160000 - 90000 ] / 8000
a = 8.75m/s^2
rounding it off to 2 significant figures, will give us 8.8 m/s^2.
