Answer:
Explanation:
18 kW = 18000 J /s
60% of 18kW = 10800 J/s
Latent heat of evaporation of water
= 2260 x 10³ J / kg
kg of water being evaporated per second
= 10800 / 2260 x 10³ kg /s
= 4.7787 x 10⁻³ kg / s
= 4.78 gm / s .

the ability to use an applied force to make an object move
Explanation:
The scientific definition of energy that relates it to work is the ability to use an applied force to make an object move.
- Energy is defined scientifically as the ability to do work.
- Work done is the force applied to make an object move in a specific direction.
Work done = Force x distance
- Since energy is the ability to do work, we are are correct to say energy is also the ability to use an applied force to make an object move.

Step by step solution :
standard deviation is given by :
![\sigma = \sqrt\dfrac{{\sum (x-\bar{x})^2}}{n}](https://tex.z-dn.net/?f=%5Csigma%20%3D%20%5Csqrt%5Cdfrac%7B%7B%5Csum%20%28x-%5Cbar%7Bx%7D%29%5E2%7D%7D%7Bn%7D)
where,
is standard deviation
is mean of given data
n is number of observations
From the above data, ![\bar{x}=24.88](https://tex.z-dn.net/?f=%5Cbar%7Bx%7D%3D24.88)
Now, if
, then ![(x-\bar{x})^2=0.0064](https://tex.z-dn.net/?f=%28x-%5Cbar%7Bx%7D%29%5E2%3D0.0064)
If
, then ![(x-\bar{x})^2=0.9604](https://tex.z-dn.net/?f=%28x-%5Cbar%7Bx%7D%29%5E2%3D0.9604)
if
, then ![(x-\bar{x})^2=1.4884](https://tex.z-dn.net/?f=%28x-%5Cbar%7Bx%7D%29%5E2%3D1.4884)
If
, then ![(x-\bar{x})^2=0.0484](https://tex.z-dn.net/?f=%28x-%5Cbar%7Bx%7D%29%5E2%3D0.0484)
If
, then ![(x-\bar{x})^2=0.1444](https://tex.z-dn.net/?f=%28x-%5Cbar%7Bx%7D%29%5E2%3D0.1444)
so, ![\sum (x-\bar{x})^2 =\frac{0.0064+0.9604+1.4884+0.0484+0.1444}{5}](https://tex.z-dn.net/?f=%5Csum%20%28x-%5Cbar%7Bx%7D%29%5E2%20%3D%5Cfrac%7B0.0064%2B0.9604%2B1.4884%2B0.0484%2B0.1444%7D%7B5%7D)
![\sum (x-\bar{x})^2 =2.648](https://tex.z-dn.net/?f=%5Csum%20%28x-%5Cbar%7Bx%7D%29%5E2%20%3D2.648)
![\sqrt{\sum \frac{(x-\bar{x})^2}{n}}](https://tex.z-dn.net/?f=%5Csqrt%7B%5Csum%20%5Cfrac%7B%28x-%5Cbar%7Bx%7D%29%5E2%7D%7Bn%7D%7D)
![\sigma =0.7277](https://tex.z-dn.net/?f=%5Csigma%20%3D0.7277)
No, Joe's value does not agree with the accepted value of 25.9 seconds. This shows a lots of errors.
