You can't calculate the force from the rate at which work is done.
10 joules in 20 seconds could be:
-- 1 newton pushing along at 50 centimeters per second, or
-- 0.1 newton pushing 5 meters per second, or
an infinite number of other possibilities.
From the data given in the question, all we know is that the 'power' is 1/2 watt.

It takes 9 seconds for a 10 Newton force to move an object 4 meters to the right What are the direction and magnitude of the force?
Direction is to the right. Magnitude is 10 Newtons.
If it takes 10 seconds and 100 N of force to move an object 10 meters What is your power?
Power (the rate of energy use) is calculated as the product of the energy exerted (work) divided by the time over which the energy is released. P = W/t To solve the example, multiply the force in Newtons by the displacement in meters to find the work in joules, then divide by the time to find the power required, in watts (joules/second, or kg-m2/sec3) 100 N x 10m = 1000 joules divided by 10 seconds = 100 watts
How much power would a person use to move a piano 10 meters in seconds using a force of 100 newtons?
A force of 100 newtons acting through a distance of 10 metersresults in 1,000 joules of energy transferred.If it all takes place in 10 seconds then the average rate of energytransfer (power) during that interval is(1,000/10) = 100 joules per second = 100 watts.
What is the potential energy in joules of a 100 kg mass 10 meters above the ground?
Energy is given in Joules with is a Newton meter. A Newton is a kilogram meter squared per second squared. A 10 kg child has 98.1 Newtons which equals 98.1 Joules.
How much work is done if a 10 Newtons force moves a 21 Kiligram object 5 Meters?
Work done = force * distance = 10 * 5 = 50 joules
How many joules does a 40 watt ight bulb convert in 10 seconds?
Four Hundred Joules
What is the power output of an engine that does 60 000 joules of work in 10 seconds?
60,000 joules per 10 seconds = 6,000 joules per second = 6,000 watts
Calculate the power in watts used if you exert 50 joules of work in 5 seconds?
Watts is joules per second, so 50 joules in 5 seconds is 10 watts.
The work to lift a weight of 5 Newtons up 2 meters is what joules?
Work = Force x Distance. The answer is 10 joules.
How many joules in 10 calories?
41.87 joules in 10 calories.

How much energy does a 100-w light bulb use in 10 s?
Power = energy / time, in SI units: watts = joules / seconds. Solving for energy: Joules = watts x seconds.
What is the potential energy in joules of a 100 kg mass 10 meters above the ground?
Energy is given in Joules with is a Newton meter. A Newton is a kilogram meter squared per second squared. A 10 kg child has 98.1 Newtons which equals 98.1 Joules.
How much power is used when 600J of work are done in 10s?
60 W
How much work is done if a 10 Newtons force moves a 21 Kiligram object 5 Meters?
Work done = force * distance = 10 * 5 = 50 joules
