A force of 13.8 N was used to lift a mass 30 cm vertically through a liquid. Calculate the work done in lifting the mass, stating the correct units.

Either from memory or using the formula booklet provided we know Work Done = Force x Distance Moved (in the direction of the force). Therefore we can use the values given and this formula to workout our answ...
