Explanation:
B. All use generators to produce electrical current
Car B, Car C, And Car E Are either speeding up or slowing down
Answer:
Option B
Explanation:
The phase difference is found by subtracting the 2.3m for the receiver from the other speaker which is 2.9m hence
Phase difference= 2.9-2.3= 0.6
My best educated guess would be
A. <span>The wave transports only energy, not matter.
I know it wouldn't be D because if the wave made by the rock wasn't strong enough to move the leaf then why did it bob up and down? (that's technically moving.) I mean it could be C but i'm pretty sure it's A.

Answer:
V = ?
C = 3 × 10^8
wavelength = 2.10 × 10^-7
wavelength = C/V
V = C/wavelength
V = 3 × 10^8/2.10 × 10^-7
V = 1.43 × 10^ 15
