Answer: 4.45m/s
Explanation:
I assume we're solving for her speed.
400m x 4 laps = 1600m
1600m / 6 minutes = 266.67m/min
(266.67m/min) x (1 minute/60 seconds) = 4.45m/s
266.67/60 = 4.45m/s
Energy is force * distance.
So force is energy/distance so 6000J/300m = 20N
The answer is:
Transverse dune
The explanation:
Transverse dune : is abundant barchan dunes It may merge into barchanoid ridges, which then grade into linear .
The transverse dunes is called that because they lie transverse, or across, the wind direction, with the wind blowing perpendicular to the ridge crest.
It is large, very asymmetrical, elongated dune lying at right angles 90° to the prevailing wind direction.
Transverse dunes have a gently sloping windward side and a steeply sloping leeward side.
They general form in areas of sparse vegetation and abundant sand are transverse dunes.
