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?
Travka [436]

    Work = (force) x (distance)

     1,008 J  =  (force) x (28 m)

Divide each side by 28m  :    (1,008 kg-m²/sec²) / (28 m)  =  force

                                           Force =  36 kg-m/s²  =  36 Newtons .
                                                                      (about 8.1 pounds)

It doesn't matter what that force accomplishes.
It could be moving a brick, lifting a fish, or pushing a little red wagon.
In order to do 1,008 joules of work in 28 meters, it takes 36 N of force,
in the direction of the 28 meters.

Give an example of a scientific hypothesis. Explain how you would test it, and how it could be falsified (proved untrue).
kaheart [24]

my hypothesis is that If you drop a piece of buttered toast, it will land butter side down.


I tested it by dropping 10 pieces of buttered toast off the table and noted on which side it landed


It could be falsified cause I just made all of this up. In essence, it's like flipping a coin, 50/50 chance so I could say that 5 landed butter up and 5 landed butter down.

What ia difference between screw and inclined plane​
Juliette [100K]

Answer:

An inclined plane makes work easier by breaking an upward or downward movement into smaller increments. Examples of inclined planes include slides, ramps, and hills. A screw is like an inclined plane wrapped around a cylinder. A screw turns a small rotational force into a larger forward driving force.
