Question

I need help with one through six please

Answer 1

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 = $\frac{distance}{time}$

 V = $\frac{50}{10}$

 V = 5 m/s

6] Acceleration = $\frac{V1-V2}{time}$

 A = $\frac{30-15}{3}$

 A = $\frac{15}{3}$

 A = 3 m/s²
