The question says, what drives surface current. The correct option is A, that is wind. There are two different current system in the ocean, they are deep circulation and surface circulation. Surface current is majorly driven by the wind. The wind is capable of moving the top 400 meters of the ocean, thereby creating ocean surface current. The pattern of the surface current is determined by the direction of the wind, forces from the earth rotation and the position of the landform that interact with the current.

Phil is riding a scooter and pushes off the ground with his foot. this causes him to accelerate at 12 m /s. Phil weighs 600 N. h

Dvinal [7]

Answer:

734.16 kg m/ $s^{2}$

Explanation:

The problem is asking for the Force of pushing off the ground.

The formula of Force is: F = mass x acceleration

Given = Mass: 600 newtons (N)

Acceleration: 12 m/ $s^{2}$

We have to convert the mass into kg first. Remember that 1 kg is equal to 9.80665 newtons.

Let x be the mass in newtons.

Let's convert: $\frac{1 kg}{9.80665 N}$ x $\frac{x}{600 N}$ = $\frac{600}{9.80665}$ = 61.18 kg

Phil's weight is 61.18 kg

Let's go back to finding the force.

F = m x a

F = 61.18 kg x 12 m/ $s^{2}$

F = 734.16 kg m/ $s^{2}$

Consider a coaxial cable (like the kind that is used to carry a signal to your TV). In this cable, a current I runs in one direc

Ira Lisetskai [31]

Answer:

0 < r < r_exterior B_total = $\frac{\mu_o I}{2\pi r}$

r > r_exterior B_total = 0

Explanation:

The magnetic field created by the wire can be found using Ampere's law

∫ B. ds = μ₀ I

bold indicates vectors and the current is inside the selected path

outside the inner cable

B₁ (2π r) = μ₀ I

B₁ = $\frac{\mu_o I}{2\pi r}$

the direction of this field is found by placing the thumb in the direction of the current and the other fingers closed the direction of the magnetic field which is circular in this case.

For the outer shell

for the case r> r_exterior

B₂ = \frac{\mu_o I}{2\pi r}

This current is in the opposite direction to the current in wire 1, so the magnetic field has a rotation in the opposite direction

for the case r <r_exterior

in this case all the current is outside the point of interest, consequently not as there is no internal current, the field produced is zero

B₂ = 0

Now we can find the field created by each part

0 < r < r_exterior

B_total = B₁

B_total = $\frac{\mu_o I}{2\pi r}$

r > r_exterior

B_total = B₁ -B₂

B_total = 0
