Work done = force multiply by displacement
so
W = 20X 10
= 200 Nm
now
1Nm = 1 joule
then the answer is 200 J

If you exert a force of 4.5N on a book to slide it across a table and do 2.7J of work in the process how far have you moved the book?
Work Done = Force x Displacement 2.7 joules = 4.5 newtons x Displacement(in meters) Displacement = 0.6 meters
If you exert a force of 20 newtons on a desk 10 meters how much work do you do on the desk?
Work = Force X Distance 20 N X 10 m = 200 N-m
What is the formula mathematical equation for work?
Work (joules) = force (newtons) * distance (metres)
An electromagnetic force 1 200 N lifts a truck 10 meters How much work was done?
There was 12k Joules of work done.
What is the formula of velocity ratio?
Effort force:Load force. For example, if you put in 10 newtons of force and the load force was exerting 5 newtons the velocity ratio would be 2:1
If you exert a force of 4.5N on a book to slide it across a table and do 2.7J of work in the process how far have you moved the book?
Work Done = Force x Displacement 2.7 joules = 4.5 newtons x Displacement(in meters) Displacement = 0.6 meters
What is the formula to find joules?
To find joules, you have to multiply the force or newtons by distance in meters.
A boy exerts an average force of 65N when he lifts a box 1.2 meters How much work does he do?
Work is equal to force x distance. If the force is specified in Newtons, and the distance in meters, then the work is in Joules.Work is equal to force x distance. If the force is specified in Newtons, and the distance in meters, then the work is in Joules.Work is equal to force x distance. If the force is specified in Newtons, and the distance in meters, then the work is in Joules.Work is equal to force x distance. If the force is specified in Newtons, and the distance in meters, then the work is in Joules.
If a worker pushes horizontally on a large crate with a force of 298 newtons and the crate moved 6.5 meters how much work do he do?
Work = force x distance = Newtons x meters = 1937 Joules.
Calculate the work done to move a dresser 7 meters using a force of 2.5 newtons?
A force of 2.5 newtons acting through a distance of 7 meters delivers 17.5 newton meters = 17.5 joules of work.
The work to lift a weight of 5 Newtons up 2 meters is what joules?
Work = Force x Distance. The answer is 10 joules.
What did James Joules do in science?
James Joules created a method in which work is calculated. work(joules) equals force(newtons) times distance(meters) or j=n times m.
How is pressure volume equal to a joule?
Calculate the work done for an object moved 62 meters by a force of 5.6 newtons in 30 minutes?
The work is 347 joules.
What is the potential energy of a crate lifted with a force of 100 newtons a vertical distance of 2 meters?
Force x distance = 100 x 2 = 200 newton-meters = 200 joules.
How much work is done by 4 newtons of force over a distance of 10 meters?
Work = force x distance = (4 x 10) = 40 newton-meters = 40 joules
