I attached the requested diagram.
<em>In the case of the magnetic field in a bar</em> by convention, the direction of the field is taken out of the north pole and towards the south pole of the magnet. These types of images are commonly made of some ferrous material.
<em>In the case of the horseshoe </em>magnet, the highly concentrated magnetic field is distinguished between its legs. In the figure it is shown in a contribution from North to South, again by agreement, however outside the two poles, the magnetic field falls rapidly. A horseshoe magnet is basically a bent bar magnet.
Answer:
8 x 10^-8 C on both the spheres.
Explanation:
Number of electrons added to A = 1 x 10^12
As the sphere A and B are identical to each other so the charge is shared equally.
Charge of one electron = 1.6 x 10^-19 C
Charge on A after wards
= number of electrons after wards x charge of one electron
qA = 0.5 x 10^12 x 1.6 x 10^-19 = 8 x 10^-8 C
Similarly, the charge on sphere B afterwards
= number of electrons after wards x charge of one electron
qB = 0.5 x 10^12 x 1.6 x 10^-19 = 8 x 10^-8 C
Answer:
1.85 m/s
102.438 m
Explanation:
From vector motion
The resultant velocity
The magnitude of speed of the speed of the boat relative to a stationary shore observer is 1.85 m/s
The distance covered is 229 m
Time = Distance / Speed
Distance = Speed of current × Time
Distance = 0.756×135.5 = 102.438 m
The boat will be 102.438 m from the initial position is the boat when it reaches the opposite shore

Birds that eat insects, this is because their is more of their primary food source for them. If they're constantly there from the locust they wont have to look for food and will be able to reproduce and populate their territory. An example would be how when the Euorpean rabbit came to Australia, it took out the native competiton and was able to eat the vast amount of plants that was perfect for their diet back in Europe, but not so much for the other animals.
