Air within the funnel of a large tornado may
have a pressure of only 0.33 atm.
What is the approximate outward force F
on a 6.5 m × 27 m wall if a tornado suddenly
envelopes the house? Atmospheric pressure is
1.013 × 105 Pa.
Answer in units of N.

a) Find the exclusion-principle for NaCl.

b) Use the equation E_ex = A/rⁿ to find thevalues for A and n. (r₀ =0.236 nm)
