Answer:
A
Explanation:
Action potentials are generated at axon hillock because it contains higher density of Na+ channels.From here it is conducted down the axon with equal intensity. It initially depolarizes then polarizes, the order is strict. However, its not affected by the distance they travel.
the neutron I hope i could help :)
Answer:
The 10-meter long rod of an SR-71 airplane expands 0.02 meters (2 centimeters) when plane flies at 3 times the speed of sound.
Explanation:
From Physics we get that expansion of the rod portion is found by this formula:
(Eq. 1)
Where:
- Expansion of the rod portion, measured in meters.
- Linear coefficient of expansion for titanium, measured in
.
- Initial length of the rod portion, measured in meters.
- Initial temperature of the rod portion, measured in Celsius.
- Final temperature of the rod portion, measured in Celsius.
If we know that
,
,
and
, the expansion experimented by the rod portion is:
