A map says that Atlanta is d1 = 729 mi in a direction of θ1 = 5.11° north of east from Dallas. The same map reflects that Chica
We deserve to usage the Cosine Law:c² = a² + b² - 2 a b cos Cd² = 729² + 562² - 2 · 729 · 562 · cos C5.11 + ( 90 - 21.1 ) = 5.11 + 68.9 = 74.01°d² = 531,441 + 315,844 + 2 · 729 · 562 · cos 74.01°d² = 847,285 - 2 · 409,698 · 0.27547 d² = 847,285 - 225,718.67d² = 621,566.33d = √621,566.33d = 788.4 milesmuzic-ivan.info:The displacement from Dallregarding Chicearlier is 788.4 miles.
A proton is relocating in a circular orlittle of radius 20 cm under a unidevelop magnetic area 0.3 t perpendicular to the velocity of the
v = 5.75 x 10⁶ m/s
The radius (r) of the circular orlittle bit taken by a charged pwrite-up is related to its rate perpendicular to a magnetic field of stamina B, and also is given by
q = charge of the particle
m = mass of the particle
Making v topic of the formula in equation (i) over gives
r = 20cm = 0.2m
B = 0.3T
v = unknown
q = charge of proton = 1.6 x 10⁻¹⁹ C
m = mass of the proton = 1.67 x 10⁻²⁷kg
Substitute the worths of m, q, B and also r into equation (ii) over to get;
Solving for v gives:
v = 5.75 x 10⁶ m/s
As such, the velocity of the proton is 5.75 x 10⁶ m/s

Please muzic-ivan.info this question provided in the picture
A plane mirror develops a digital picture behind the mirror. The picture is as far behind the mirror as the object is in front of it. A cannot see his image bereason the size of the mirror is as well brief on his side. However before, he have the right to watch the objects inserted at points P and Q, however cannot watch the object placed at allude R
Hope this helps Buddy!
