Answer:

Work done= Energy transferred

Explanation:

Work is the transfer of energy. In physics we say that work is done on an object when you transfer energy to that object. If you put energy into an object, then you do work on that object (mass).

Dominik [7]

Answer:

$\phi=4344.72Nm^2/c$

Explanation:

From the question we are told that:

Dimension of Wall:

$(L*B)=(8.7 m * 3.2 m)$

Electric field $B=210 N/C$

Angle $\theta =42 \textdegree North$

Generally the equation for electric Flux is mathematically given by

$\phi=EAcos\theta$

$\phi=210*(8.7*3.2)*cos 42$

$\phi=4344.72Nm^2/c$

Two round concentric metal wires lie on a tabletop, one inside the other. The inner wire has a diameter of 18.0 cm and carries a

Helen [10]

Answer:

Explanation:

The wires are in circular shape . They have common center .

magnetic field due to circular wire is given by the formula

B = $\frac{\mu_0\times I }{2r}$

where I is current , r is radius of the coil .

magnetic field due to inner wire

= $\frac{\mu_0\times 10 }{2\times.09}$

magnetic field due to outer wire

= $\frac{\mu_0\times I }{2\times.15}$

These should be equal and opposite so that by cancelling each other , they create zero field.

$\frac{\mu_0\times 10 }{2\times.09}$ = $\frac{\mu_0\times I }{2\times.15}$

I = 16.66 A

Direction of current should be in opposite direction ie anticlockwise when looking from above.

What two forces limit the height to which capillary action will take water up a tube?

Jobisdone [24]

Capillary action occurs when the adhesion to the walls is stronger than the cohesiveforces between the liquid molecules. The height to which capillary action will take water in a uniform circular tube (picture to left) is limited by surface tension and, of course, gravity.

Hope this helps. :)
