Answer:
W = 0
Explanation:
When an electron moves perpendicular to a uniform B-field. If the field is in a vacuum, the magnetic field B is the dominant factor determining the motion. Since the magnetic force F is perpendicular to the direction of travel, an electron follows a curved path in a magnetic field. The electron continues to follow this curved path until it forms a complete circle. Another way to look at this is that the magnetic force F is always perpendicular to velocity v, so that it does no work on the charged particle. The particle’s kinetic energy and speed thus remain constant. The direction of motion is affected but not the speed.
W = F*d*Cos ∅ = F*d*Cos 90° = 0 where d is the displacement.
The pic shown can help to understand the explanation.
This should include distances. Displacement is the shortest distance from point A to point B. Distance is the total length of travel. For an example I have included a simple map.
Displacement would not be an accurate representation of the driving instructions because it would not tell the total length of travel. Basically, the driver would be going through buildings if you told them displacement. Directions would tell them the roads traveled.
Unfortunately, unless you include a picture of the hill, you can't solve for what would happen. However,
you can find KE from the question, and use that to determine how high it could go on the slope.
KE= 1/2 mv^2
1/2*1200*196 = 117600 Joules.
Hope this helped!
The actual answer is B) Chlorine
According to the Bohr Model diagram, the atom has seventeen electrons. This makes it Chlorine.
