Dust Particles in a Grain Elevator Frequently Have Masses of the Order

question 6

Multiple Choice

Dust particles in a grain elevator frequently have masses of the order of $1.0 \times 10 ^ { - 9 } \mathrm {~kg}$
If, to a first approximation, we model the dust particles as an ideal gas, what would be the rms speed of such a particle in air at $27 ^ { \circ } \mathrm { C } \text { ? }$ The Boltzmann constant is $1.38 \times 10 ^ { - 23 } \mathrm {~J} / \mathrm { K }$

• A) \(5.6 \times 10 ^ { - 5 } \mathrm {~m} / \mathrm { s }\)
• B) \(7.8 \times 10 ^ { - 4 } \mathrm {~m} / \mathrm { s }\)
• C) \(3.5 \times 10 ^ { - 6 } \mathrm {~m} / \mathrm { s }\)
• D) \(5.2 \times 10 ^ { - 3 } \mathrm {~m} / \mathrm { s }\)
• E) \(4.9 \times 10 ^ { - 2 } \mathrm {~m} / \mathrm { s }\)
