Work = (force) x (distance) = 7 x 2.4 = 16.8 joules

What does it mean in light years when an object is 3.8x10m?
Divide this distance - 38 meters, is it? - by the distance of a light-year (about 9.5 x 1015 meters).
Which gains more gravitational potential energy a 4 N object lifted 3.0 m or a 5 N object lifted 2.0 m?
Let's see. First.....,F = mam = F/am = 4 N/9.8 m/s2= 0.408 kilograms----------------------m = 5 N/9.8 m/s2= 0.510 kilograms-----------------------------secondly......,PE = mghPE = (0.408 kg)(9.8 m/s2)(3.0 meters)= 11.99 Joules==============A 4 Newton object lifted 3 meters gains more potential energy.
Does force affect how far an object travels?
Distance is measured in meters, wind resistance does not come into it
How do you calculate the velocity of a moving object?
The change in distance divided by change in time. So say it moved 10 meters in 5 seconds, it would be 2 meters per second.
Can newtons measure distance?
No, because a newton is a measurement of force. You can only convert units that measure the same object. For example you can convert meters to feet because they are both measurements of distance.
An object with a mass of 21 kilograms is lifted through a distance of 7 meters How much?
question 24 on penn foster is C.
An object of mass 4.5 is lifted through a distance of 10m H ow much work is done?
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
How much work is done when 700 n object is lifted straight up a distance of 4 meters?
700 x 4 = 2,800 newton-meters = 2,800 joules
An object with a mass of 21kilograms is lifted through a distance of 7 meters How much work is done?
use the formula W = mgs W stands for work done in joules m stands for mass of the object g stands for gravity s stands for the distance the object is lifted W = mgs W = 78kilograms•9.8m/s2•6meters W = 4586.4 J (joules) answer would be 4,586.4 J
How much work is done when an object with a mass of 78 kilograms is lifted through a height of 6 meters?
78*6*9.8 N = 4586.4 N
Does the amount of newtons affect the distance of an object?
Distance is measured in meters
How much work would you do if you applied a 200 Newtons to an object and moved it 0 meters?
If an object does not move, no work is performed. Work is performed by a force acting through a distance.
How do objects acquire potential energy?
For an object to require potential energy a force must be acting on it in a certain direction. Even though the object doesnt move doesnt mean it has potential energy. The most common force of otential energy is Gravity. When an object is lifted off the ground gravity becomes stronger. For a formula of proof then use E=FxD (Energy=Force applied x Distance travelled). If a ball has been lifted by 10 Meters with a force of 500 Newtons then it has a Potential Energy of 5000 Newton Meters,

What is the distance of an object that has an angular diameter of 100 seconds of arc and a linear diameter of 30 meters?
30 meters subtends 100 seconds of arc.I get a distance of 61,879 meters.
What is the product of the force on an object and the distance through which the object is moved?
work
The distance an object travels in certain direction in a certain time?
This is known as displacement, and is generally measured in meters :)
