A bumblebee has a mass of 0.22 g . If its speed is 11.50 m/s , calculate its kinetic energy K E .

K.E. = 1.45475 ×10⁻² J

Explanation:

Mass (m) =0.22 g = 0.22×10⁻³ Kg, Speed (v) =11.50 m/s

Required: K.E=?

Sol: Formula for K.E. = 1/2 ( m v² ) =0.5 m v²

K.E. = 0.5 × 0.22×10⁻³ Kg × ( 11.50 m/s)²

K.E. = 0.0145475 J

K.E. = 1.45475 ×10⁻² J

a lot of it means it can be "burned" for energy and sold at one price. if it is scarce, the price will go up

small = small current large mag large current
