D. Was a leader in the woman's suffrage movement
Answer:
C) 1.0 m
Explanation:
The component of the velocity parallel to the sidewalk is:
vₓ = v cos θ
vₓ = 0.1 m/s cos 45°
vₓ = 0.0707 m/s
The distance traveled after 14 seconds is:
d = vₓ t
d = (0.0707 m/s) (14 s)
d = 0.99 m
Closest answer is C) 1.0 m.
Answer:
Magnitude of the net force on q₁-
Fn₁=1403 N
Magnitude of the net force on q₂+
Fn₂= 810 N
Magnitude of the net force on q₃+
Fn₃= 810 N
Explanation:
Look at the attached graphic:
The charges of the same sign exert forces of repulsion and the charges of opposite sign exert forces of attraction.
Each of the charges experiences 2 forces and these forces are equal and we calculate them with Coulomb's law:
F= (k*q*q)/(d)²
F= (9*10⁹*3*10⁻⁶*3*10⁻⁶)(0.01)² =810N
Magnitude of the net force on q₁-
Fn₁x= 0
Fn₁y= 2*F*sin60 = 2*810*sin60° = 1403 N
Fn₁=1403 N
Magnitude of the net force on q₃+
Fn₃x= 810- 810 cos 60° = 405 N
Fn₃y= 810*sin 60° = 701.5 N
Fn₃ = 810 N
Magnitude of the net force on q₂+
Fn₂ = Fn₃ = 810 N
Based on the nature of constructive interference,
none of the wave intersections will produce constructive interference.
<h3>What is constructive interference?</h3>
Constructive interference is interference that occurs when two waves of the same frequency amplitude and wavelength travelling in the same direction are superposed with the resultant effect of reinforcement of both waves to produce a larger wave.
Constructive interference occurs when the path difference between two identical waves at a point is:
where n = 0, 1, 2, ...
For the various intersections:
- 1.77 cm crest intersecting with a 0.65 cm crest; n = 1.77/0.65 = 2.7
- A 1.2 mm crest intersecting with a 3.9 mm trough is destructive.
- A 4.55 N trough intersecting with a 1.59 N trough; n = 4.55/1.59 = 2.8
- A 0.44 inch trough intersecting with a 0.72 inch crest is destructive.
- A 7.42 mm trough intersecting with a 1.93 mm trough; n = 7.42/1.93 = 3.8
Therefore, none of the wave intersections will produce constructive interference
