The particle that flows to produce an electric current is the electron (c)...GOOD LUCK!!!
Answer:
Inducted Magnetic field will be toward from you
Inducted current direction will be counter clockwise.
Explanation:
Lenz's law states that the direction of the current induced in a wire by a changing magnetic field is such that the magnetic field created by the induced current opposes the initial changing magnetic field.
So if the field begins to decrease, the induced magnetic field would try to stop this, so its direction will be the same as the magnetic field, toward from you.
This induced magnetic field is produced by the current in the wire. If the inducted magnetic field will be toward you, the right hand rule says that the direction from the inducted current will be counter clockwise.
Answer:
(a) 2.5 cm
(b) Yes
Solution:
As per the question:
Mass of Uranium-235 ion, m =
Mass of Uranium- 238, m' =
Velocity, v =
Magnetic field, B = 0.250 T
q = 3e
Now,
To calculate the path separation while traversing a semi-circle:
The radius of the ion in a magnetic field is given by:
R =
Now,
By putting suitable values in the above eqn:
(b) Since the order of the distance is in cm, thus clearly this distance is sufficiently large enough in practical for the separation of the two uranium isotopes.
Answer:
Zero...
Explanation:
When the glass road is rubbed with silk clothes, it get charged positively. When it made contact with the metallic rod, the positive charge is transferred to the metallic rod (The wooden post will have no effect because it doesn't interact with charge on metals). When the metallic rod make contact with ground with intact glass rod, all the charge transfers to the ground because of the high negative potential of Earth, So, in the end all the net charge become zero.
