5multiply by 30=150.
*SOLUTION* Force=16N Area=16cm2 {square} =16×10,000=0.0016 Pressure=Force/Area =16N /0.0016m2 {square} =10,000 Pa
10 Equivalently, the number 6 is equal to half the sum of all its positive divisors: ( 1 + 2 + 3 + 6 ) / 2 = 6. The next perfect number is 10 = 1 + 2 + 3 + 4. This is followed by the perfect numbers (1+2+3+4+10)/2 20 / 2 = 10
28 Equivalently, the number 6 is equal to half the sum of all its positive divisors: ( 1 + 2 + 3 + 6 ) / 2 = 6. The next perfect number is 28 = 1 + 2 + 4 + 7 + 14. This is followed by the perfect numbers (1+2+4+7+14+28)/2 56 / 2 = 28
