Question
a force of 13.8N was applied to lift a mass 30cm vertically throught a liquid.calculate the work done in lifting this maths
Solution
To calculate the work done, we use the formula:
Work Done = Force x Distance
Given in the problem, the force (F) is 13.8N and the distance (d) is 30cm. However, we need to convert the distance from cm to meters because the standard unit of distance in physics is meters.
1 meter = 100 cm So, 30 cm = 30/100 = 0.3 meters
Now we can substitute the values into the formula:
Work Done = 13.8N x 0.3m = 4.14 Joules
So, the work done in lifting the mass is 4.14 Joules.
