Acceleration due to gravity, on the surface of the eartth, is approx 9.8 m/sec2.
Using this value, the mass of 645 N = 645/9.8 kg = 65.8 kg.
a + b = 645 a - b = 151 Add: 2a = 796 a= 398, making b = 247
The potential energy can be calculated using the formula: potential energy = weight * height. Substituting the values, potential energy = 645 N * 4.55 m = 2934.75 Joules.
645 X 73 use LONG MULTIPLICATION. 645 x 73 45150 ( 70 X 645) ( multiply by '7' and then put as '0' on the end). +1935 ( 3 x 645) 47058 ===== The answer.
The divisors of 645 are: 1, 3, 5, 15, 43, 129, 215, 645.
The factors of 645 are: 1, 3, 5, 15, 43, 129, 215, 645.
645 kilolitres = 645 000 litres1 kL = 1000 L
645 - 19 = 626
645 = DCXLV
137 + 645 = 782.
