When heat moves from the ocean to the surrounding air, which is this an example of?
Blizzard [7]
B) The transfer of energy from the hydrosphere to the atmosphere

This is because oceans are part of the hydrosphere. As the air warms it flows up into the atmosphere.

Hope this helps!

Niobium metal becomes a superconductor when cooled below 9 K. Its superconductivity is destroyed when the surface magnetic field
morpeh [17]

To develop the problem it is necessary to apply the concepts related to Magnetic Field.

The magnetic field is defined as

B = \frac{\mu_0 I}{2\pi r}

Where,

\mu_0 = Permeability constant in free space

r = Radius

I = Current

Our values are given as,

B = 0.1T

d = 4.5mm

r = 2.25mm

If the maximum current that the wire can carry is I, then

B = \frac{\mu_0 2I}{4\pi r}

I = \frac{Br}{2\frac{\mu_0}{4\pi}}

I = \frac{(0.1T)(2.25*10^{-3}m)}{2(1*10^{-7}N/A^2)}}

I = 1125A

Therefore the maximum current is 1125A

A race car starts at rest and accelerates north at 12.27 m/s2 for 3.19 seconds. What
IRISSAK [1]
Final velocity is equal to initial velocity plus at (where a is acceleration and t is time), so Vf = Vi + at

Using that formula;

Vf = 0 + 12.27(3.19)

Vf = 39.14 m/s

Note: you started from rest, so your initial velocity is 0.
