Answer:
B. A line angled upward
Explanation:
velocity is plotted along y- axis and time is plotted along x- axis so we get a line angled upward
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
Set up a free body diagram.
<span>and by reason, Tcd = Tbd </span>
<span>Tbd y = 275 - 300*sinθ </span>
<span>Tcd y = Tc - 300*sin30 </span>
<span>Tbd x = 300*cosθ </span>
<span>Tcdx = 300 * cos30 </span>
<span>Tbd^2 = (275 - 300*sinθ)^2 + (300*cosθ)^2 </span>
<span>Tcd^2 = (300*sin30)^2 + (300 * cos30)^2 </span>
<span>(275 - 300*sinθ)^2 + (300*cosθ)^2 = (300*sin30)^2 + (300 * cos30)^2 </span>
<span>etc.</span>
Diamonds and iron, as they can't be easily put back or recreated. Remember to make sure yourself.
Hope this helps :)
Its accelarating from 1-10 i know that because the line is going up. i hope i helped
