Work is done in lifting is equal to work done in opposing gravity. Work done in opposing gravity = weight times distance = 700 x 4 =2800 joules
Work is force x distance = 700 x 4 = 2800 Joules
Work = Force x distance = 700N x 4m = 2800N•m = 2800 Joules
I believe that when you say 'lifted through', you mean lifted to a height of 10m. If so, the amount of work is such: Work= Force x Distance which have the units (Joules = Newtons x meters) When the object is lifted, it increases in its potential energy. The equation for this is: Potential energy = mass x gravitational force x height = 4.5 x 9.81 x 10 =441.45 Joules As 1 joule = 1 newton x meters and we have 441.45 Joules, 441.45 joules of works is done! :D
The idea here is to multiply the force by the distance.
Work = Force (N) x Distance (m) Therefore, the units of work are N-m, or Newton-meters. F=700N D=4m W=FxD = 700x4 = 2800N-m
Work is force x distance = 700 x 4 = 2800 Joules
Work = Force x distance = 700N x 4m = 2800N•m = 2800 Joules
700 x 4 = 2,800 newton-meters = 2,800 joules
Work = (force) x (distance) = 7 x 2.4 = 16.8 joules

No, the amount of work done will be the same. The lever provides mechanical advantage by multipling force times distance applied. A 1 kg object will need about 10 Joules of work to lift it up a vertical distance of 1 meter, no matter whether it is lifted straight up, or over a greater distance such as up a ramp, or with a lever.
The idea here is to multiply the force by the distance.
Force x distance = 100 x 2 = 200 newton-meters = 200 joules.
Work = Force (N) x Distance (m) Therefore, the units of work are N-m, or Newton-meters. F=700N D=4m W=FxD = 700x4 = 2800N-m
Work = (force) x (distance) = (10) x (4) = 40 joules
Work = force x distance = 20 x 2 = 40 newton-meters = 40 joules
Work = force * distance Work = 23N * 2.3 meters = 53 Joules of work is done ==================
