Answer:
1] 8500000 = 8.5 × 10⁶
2] .000072 = 7.2 × 10⁻⁵
3] 5.3 × 10⁴ = 53000
4] 2.8 × 10⁻³ = 0.0028
5] Velocity = [tex]\frac{distance}{time} [/tex]
V = [tex]\frac{50}{10} [/tex]
V = 5 m/s
6] Acceleration = [tex]\frac{V1-V2}{time} [/tex]
A = [tex]\frac{30-15}{3} [/tex]
A = [tex]\frac{15}{3} [/tex]
A = 3 m/s²
