Respuesta :

A minimum stream velocity needed to keep a 6.4 cm diameter particle in motion must be 100 cm/s.

It can be concluded from Hjulstrome curve, a graph used to determine whether stream will transport, erode or deposit particles. The faster is the current, the heavier particles it could transport.

Answer:

200 cm/s

Explanation:

Don't listen to the other answer! I got this question marked wrong for 100cm/s, the correct answer is 200cm/s.
