Answer:

12 seconds

Explanation:

In physics, power can be defined as a rate of energy transfer. In other words it shows how much energy was transtered over a period of time.

There is a simple equation that connects all of this:

P = E/t,

P is power

E is energy

t is time

Here, we are given power of a blender of P = 400 W, and total energy transfer of E = 4800 J. So:

400W = 4800J / t

t = 4800/400

t = 12s
