Answer:
Because winding roads have a gentle slope on hills, so it's easy to climb it than a steepy.
1 ft =12 in
4 in = 0.333 ft
volume = (п/4)*(0.333)² = 0.087 ft²
vol. flow = spead *volume
=3 ft/s * 0.087 ft²
vol flow = 0.261 ft³/s
Answer:

Explanation:
Flux is given by

A = Area

E = Electric field = 76.7 N/C
Angle is given by


The flux through the sheet is
