How much force is needed to move a brick with a mass of 345-kg a distance of 28m while doing 1008 J of work?
The work done on the brick is given by the equation W = F*d, where W is the work done (1008 J), F is the force needed, and d is the distance moved (28m). Therefore, rearranging the equation to solve for F gives F = W/d. Substituting in the values gives F = 1008 J / 28 m = 36 N. So, a force of 36 Newtons is needed to move the 345-kg brick a distance of 28m while doing 1008 J of work.

When doing work you can decrease force by?
When doing work, you can decrease force by using simple machines like pulleys, levers, or ramps to distribute the force needed to perform the work. These machines help reduce the amount of force required to move an object by increasing the distance over which the force is applied. Additionally, using lubricants to reduce friction between surfaces can also decrease the force needed to do work.
What machine increases distance and how is the force changed?
A lever can be used to increase distance by applying a smaller input force over a longer distance to lift a heavier load. The force needed to lift the load is changed by adjusting the length of the lever arm or by changing the position of the input force relative to the pivot point.
If you were pushing very hard against a brick wall would you be doing work?
Yes, pushing against a brick wall would require force and displacement, which are the two components of work. You would be exerting energy to apply a force on the wall, but if the wall doesn't move, there would be no work done on the wall.
When doing wwork with a simple machine what happens when the effort distance is increased?
When the effort distance on a simple machine is increased, it allows for less force to be applied to achieve the same work output. This happens because the work done is a product of force and distance, thus increasing the effort distance decreases the force required.
The illustration shows Beatrice pushing on a heavy box Beatrice pushes with a force of 40 N How can you determine if Beatrice is doing work on the box?
To determine if Beatrice is doing work on the box, we need to know the distance over which she is pushing and the direction of the force she is applying. Work is done when a force is applied in the direction of motion over a distance. If Beatrice is pushing the box in the direction of motion over a distance, then work is being done on the box.
What is a rectanular block of clay baked in the sun or a kiln?
A brick. I'm doing the same exact assignment right now. :)
How do you clean brick walls?
There are professional firms available in market that provides services of Brick Cleaning in London. Instead of doing it all by yourself, you should opt to a professional.
What tools are needed?
It depends on what you are doing
How do you get the red brick on escape from echo base?
To obtain the red brick in "Escape from Echo Base" level in Lego Star Wars: The Complete Saga, you need to destroy all six cannons found on the left side of the level. Doing so will reveal the red brick.
Can apple brick your phone now that jailbreaking is leagal?
i think they still will because they are doing anything to stop you from jailbreaking.
How exerting a force differs from doing work?
In everyday popular usage, "work" means effort, sweat, things like that. But the formal scientific definition of work is: (Force) times (distance). You can push on a brick wall as hard as you want for as long as you want; no work has been done until the wall moves, because the force hasn't moved through a distance.

You are in a long distance relationship and you think he is cheating?
well the thing about long distance relationships is that you cant really tell what they are doing and when they are doing it. so if i was you i would just break up with him or ignore it
Is it true that no force is needed to keep an object doing what it is already doing?
Deep question, but at the end of the day, Yes. It is true that no force is needed. Because if you put an object into space for example, it will continue what it is doing. If there was no gravity, it would just sit there.
