Answer:
The new radius is three times the initial radius
Explanation:
The magnetic force is given by the equation
F = q v x B
Where the blacks indicate vectors, q is the electric charge, v the velocity of the particle and B the magnetic field. The scalar magnitude of this force is
F = q v B sin θ
Where θ is the angle between the velocity and the magnetic field.
As the force is perpendicular to the velocity, the particle describes a circular motion, using Newton's second law we can find the acceleration that is centripetal.
F = ma
a = v² / r
q v B = mv² / r
R = mv / qB
Let's calculate for the new speed (v₂ = 3v)
R₂ = (m / qB) 3v
R₂ = 3 R
R₂ / R = 3
The new radius is three times the initial radius
“RESISTANCE” is a property that determines how much current will flow for a given source voltage, whereas a “RESISTOR” is a device that controls the current in a circuit.
At 305 and 309 it was negative because it is going down
at 300 and 301 and 305 it was positive because its going up
at 302/303/304/306/309 she wasn't accelerating at all because it is staying the same
Answer:
A regulation game consists of 7 innings unless extended because of a tie score or unless shortened because the home team needs none or only a fraction of its 7th inning or unless 1 team is leading by 10 runs after 5 innings.
