During a science lesson on changes, Ms. Sloan's students made mixtures of sulfur (the yellow substance) and iron filings (the black substance. Ms. Sloan challenged her students to separate the two substances and one group easily completed the task by using a magnet to lift the iron filings from the mixture. Next, Ms. Sloan poured the same mixture into a test tube and heated it in the Bunsen burner flame. What was the result of heating the mixture?

weight of the box is given as

here this is placed on the inclined of angle 42 degree

now this weight will have two components one is along the incline other is perpendicular to it

so here we need to apply a force parallel to incline opposite to its component of weight

so here the component of weight is given as

here we have

so it requires 75 n force to move it upwards

i really dont know but i will try okay.

so i think u would just add all them up and get your answer..

the ima (higher than 1m) will be greater than the ima with the height of 1m.
