Question

I need help with one through six please

Answer 1

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 =
`(distance)/(time)`

V =
`(50)/(10)`

V = 5 m/s

6] Acceleration =
`(V1-V2)/(time)`

A =
`(30-15)/(3)`

A =
`(15)/(3)`

A = 3 m/s²
