Nerve impulses are carried along axons, the elongated fibers that transmit neural signals. We can model an axon as a tube with a

n inner diameter of 10 μm. The tube wall is insulated, but the fluid inside it has a resistivity of 0.50 Ω⋅m. What is the resistance of a 2.0-mm-long axon? Express your answer with the appropriate units

Answer:

Explanation:

For resistance , the formula is

R = ρ l / S where ρ is resistivity , l is length and A is cross sectional area .

= .5 x 2 x 10⁻³ / 3.14 x (5 x 10⁻⁶)²

= .0127 x 10⁹

12.7 x 10⁶

12.7 MΩ

What would happen when there is a collision between two objects having unequal masses
Mashcka [7]

Answer:

Newton's Laws Applied to Collisions. Newton's third law of motion is naturally applied to collisions between two objects. ... Thus, if the colliding objects have unequal mass, they will have unequal accelerations as a result of the contact force that results during the collision.

Jessica is visiting a park with her mother. Jessica sits on a swing. Her mother pulls the swing to a height of 3 meters above th
Tpy6a [65]

You are given Jessica's height of the swing 3 meters above the ground, velocity at 5m/s²  and her mass of 44 kilograms. Since there is no image given, I will assume that the position at maximum and minimum height, that is 3 and 0 meters.


Position at maximum height

PE = mgh

PE = 44 kg *9.8m/s²*3

PE = 1,294 J


Position at minimum height

PE = 0 J


Position at maximum velocity

KE = 1/2*mv²

KE = 1/2*44 kg*(5m/s²)²

KE = 550 J


Position at minimum velocity

KE = 0 J
