Answer:
The phase difference between these two waves is 141.1⁰
Explanation:
The displacement of the wave is given as;

Amplitude, A = 2yₓCos(¹/₂Φ)
Since the amplitude of the combination is 1.5 times that of one of the original amplitudes = yₓ = 1.5 × A = 1.5A
A = 2(1.5A)Cos(¹/₂Φ)
A = 3ACos(¹/₂Φ)
¹/₃ = Cos(¹/₂Φ)
(¹/₂Φ) = Cos ⁻(0.3333)
(¹/₂Φ) = 70.55°
Φ = 141.1°
The phase difference between these two waves is 141.1⁰
It takes 3 half-lives:
1. 1000 -> 500
2. 500 -> 250
3. 250 ->125
I'm not sure about the Virginia thing so good luck!
And congratulations on being my first answer-person!!
Answer:
10.4mm
Explanation:
2 pages = 1 leaf
200 pages = 100 leaves
100 × 0.10 = 10 mm thickness
Total thickness = 2(0.20) +10 = 0.4+10 = 10.4mm
Answer:
148(m/s)
Explanation:
V_final = V_current + (acceleration) x (time)
= 4 + 80 x 1.8 = 148 (m/s)
