Question

The work done by a machine in 2 minutes is 480J. Calculate the power of the machine​

Answer 1

I think the power is 4

Explanation:

480J / 120 = 4

Put 2 mins into seconds which is 120 seconds

Sorry if it is wrong :)

Answer 2

`4\text{ watts}`

Explanation:

In physics, the power of a machine is given by
`P=(W)/(\Delta t)`, where
`W` is work in Joules and
`\Delta t` is time in seconds.

Convert 2 minutes into seconds:

2 minutes = 120 seconds.

Substitute
`W=480` and
`\Delta t=120` to solve for
`P`:

`P=(480)/(120)=\boxed{4\text{ watts}}`
