B. The object stops from a velocity of 12.0 m/s
Answer:
the strength of the magnetic field inside the solenoid is 6.278 x 10⁻³ T.
Explanation:
Given;
length of the wire, = 34.9 m
length of solenoid, L = 0.24 m
radius of the solenoid, r = 0.051 m
current in the solenoid, I = 11.0 A
The number of turns of the wire is calculated as follow;
The strength of the magnetic field inside the solenoid is calculated as follows;
Therefore, the strength of the magnetic field inside the solenoid is 6.278 x 10⁻³ T.
- Initial velocity (u) = 10 m/s
- Final velocity (v) = 22 m/s
- Time (t) = 12 s
- Mass (m) = 200 Kg
- Let the acceleration be a.
- By using the equation of motion,
v = u + at, we have
- 22 m/s = 10 m/s + 12 s × a
- or, 22m/s - 10 m/s = 12 s × a
- or, 12 m/s = 12 s × a
- or, a = 1 m/s^2
- Let the force be F.
- We know, F = ma
- Therefore, the force on the accelerated object (F)
- = ma
- = (200 × 1) N
- = 200 N

Answer:
orbitals
Explanation:
The region where an electron is most likely to be is called an orbital. Each orbital can have at most two electrons. Some orbitals, called S orbitals, are shaped like spheres, with the nucleus in the center.
Magnetism is a property of materials that respond at an atomic or subatomic level to an applied magnetic field. For example, the most well known form of magnetism is ferromagnetism such that some ferromagnetic materials produce their own persistent magnetic field. However, all materials are influenced to greater or lesser degree by the presence of a magnetic field. Some are attracted to a magnetic field (paramagnetism); others are repulsed by a magnetic field (diamagnetism); others have a much more complex relationship with an applied magnetic field. Substances that are negligibly affected by magnetic fields are known as non-magnetic substances. They include copper, aluminium, gases, and plastic.
<span>The magnetic state (or phase) of a material depends on temperature (and other variables such as pressure and applied magnetic field) so that a material may exhibit more than one form of magnetism depending on its temperature, etc.
Or
</span><span>If it's a multiple choice question this is the best answer: </span>
<span>A magnetic field surrounds each magnet, which affects other objects with magnetic fields
</span><span>hope this helpsss.
and can you help me as well with two questions if you dont mind
