TO find: Express pressure
Express space pressure equals fraction numerator 2 straight T over denominator straight R end fraction comma space where space straight T space is space tension space and space straight R space is space radius Express space pressure equals fraction numerator 2 cross times 7.3 cross times 10 to the power of negative 2 end exponent over denominator 10 to the power of negative 1 end exponent end fraction equals 1.46 space straight N divided by straight m squared
