= 2,4 × 104 = 1,28 × 104 = 1,304 × 106
2.4 8 300 000 + 2 450 000 = 10 750 000 = 1,075 × 107 2.5 7 680 000 + 9 346 000 = 17 026 000 = 1,7026 × 107 2.6 1 514 700 + 23 760 000 = 25 274 700 = 2,52747 × 107
3.1 2 kg 4.1 50 N
= 2 kg × 10 m/s2 = 20 kg.m/s2 = 20 N
= 50 ÷ 10 = 5 kg
5.1 13 000 000 Pa = 13 MPa 3.2 3,5 kg 4.2 70 N
= 3,5kg × 10 m/s2 = 35 kg.m/s2 = 35 N
= 70 ÷ 10 = 7 kg
5.2 17 500 000 Pa = 17,5 MPa
