In the figure below, a long circular pipe with outside radius R = 2.57 cm carries a (uniformly distributed) current i = 10.4 mA

into the page. A wire runs parallel to the pipe at a distance of 3.00R from center to center. Find the magnitude of the current in the wire in milliamperes such that the ratio of the magnitude of the net magnetic field at point P to the magnitude of the net magnetic field at the center of the pipe is 4.74, but it has the opposite direction.

What would happen if you charged a balloon by
Luda [366]

When you rub a balloon against your hair or clothing, electrons that were previously on the hair/clothing will "jump" onto the balloon. Therefore, the balloon now has a negative charge accumulated on its surface.

When you bring that balloon near another balloon with a neutral charge, they will stick to each other, because the electrons on the surface will be attracted to the positive charges on the other. The positive charges that were previously randomly oriented now line up at the surface. However, after some time, the electrons move around back to their former random positions.

A hot-air balloon is descending at a rate of 2.3 m>s when a pas- senger drops a camera. If the camera is 41 m above the groun
zheka24 [161]

Answer:

a) t = 2.64s

b) Vf = -28.7m/s

Explanation:

If the balloon is descending, the velocity is -2.3m/s. So the equation to describe the postion of the falling camera is:

Y = Vo*t - \frac{g*t^{2}}{2}

-41 = -2.3*t - \frac{10*t^{2}}{2}    Solving for t, we get:

t1 = -3.1s     and      t2 = 2.64s We discard the negative time and use the positive one.

The velocity of the camera will be:

Vf = Vo - g*t = -2.3 - 10*2.64 = -28.7m/s

The charge density of a uniformly charged disk 0.420 m in diameter is 2.92 ✕ 10−2 C/m2. What is the magnitude of the electric fi
iragen [17]

Answer:

E = {(Charge Density/2e0)*(1 - [z/(sqrt(z^2 - R^2))]}

R is radius = Diameter/2 = 0.210m.

At z = 0.2m,

Put z = 0.2m, and charge density = 2.92 x 10^-2C/m2, and constant value e0 in the equation,

E can be calculated at distance 0.2m away from the centre of the disk.

Put z = 0.3m and all other values in the equation,

E can be calculated at distance 0.3m away from the centre of the disk
