Answer:
Explanation:
Assume the stone consists of basalt, which has a density of 3.0 g/cm³.
Average velocity during a time interval is
(the straight-line distance between the starting point and ending point,
regardless of the route followed along the way)
divided by
(the length of the time interval)
in the direction
(from the starting point to the finishing point).
Frequency = (speed) / (wavelength)
Speed = 3 x 10⁸ m/s
Wavelength = 3 cm = 0.03 m
Frequency = (3 x 10⁸ m/s) / (0.03 m)
Frequency = (3 x 10⁸ / 0.03) (m / m-s)
Frequency = 1 x 10¹⁰ Hz (10 Gigahertz)
Answer:
Ben's average speed was twice Debby's average speed.
Explanation:
Ben covered a total distance of 16 miles (10+4+2) and Debby covered 8 miles (3+2+2+1) which is half of what Ben covered. As they both reached the place in the same amount of time it tells us Ben was faster.
