The direction that an ocean current travels can be altered by the movement of the Earth's rotation on its axis. This is known as
Nitella [24]

The direction that an ocean current travels can be altered by the movement of the Earth's rotation on its axis. This is known as the Coriolis effect.

<h3>What is Coriolis effect in simple terms?</h3>

Coriolis effect is the result of Earth's rotation on weather patterns and ocean currents. The Coriolis effect makes storms swirl in the clockwise direction in the Southern hemisphere while on the other hand, storms counterclockwise in the Northern Hemisphere. This effect can cause change in the direction of the ocean current due to the rotation on its axis.

So we can conclude that the direction that an ocean current travels can be altered by the movement of the Earth's rotation on its axis. This is known as the Coriolis effect.

Measurements are made of the longitudinal axoplasmic resistance of two unmyelinated axons. Along a 1 cm length of one axon, whic
lorasvet [3.4K]

Answer:

0.625‬ MOhms

Explanation:

Since the resistance of the unmyelinated axon ,R is inversely proportional to the square of its diameter, d

R ∝ 1/d²

R₁/R₂ = d₂²/d₁² where R₁ = resistance of first axon = 10 MOhm, d₁ = diameter of first axon = 1 mm, R₂ = resistance of second axon and d₂ = diameter of second axon = 4mm

So, R₂/R₁ = d₁²/d₂²

R₂ = (d₁²/d₂²)R₁

R₂ = (d₁/d₂)²R₁

substituting the values of the variables into the equation, we have

R₂ = (d₁/d₂)²R₁

R₂ = (1 mm/4 mm)²10 MOhms

R₂ = (1/4)²10 MOhms

R₂ = (1/16)10 MOhms

R₂ = ‭0.0625‬ × 10 MOhms

R₂ = ‭0.625‬ MOhms
