PLEASE HELP ME WILL GIVE BRAINLIST AND POINTS!!! Q: A compass contains a magnet. The magnet responds to Earth’s magnetic field. The magnet’s north pole points north from most locations on Earth. Based on what you learned about magnetic force, make three predictions. Predict the approximate size of Earth’s magnetic field and the approximate location of its North and South Poles. Give a reason for each prediction.

  distance on the y-axis and time on the x-axis.

explanation:

the instantaneous velocity = change in position/time taken

the slope of the graph should give instantaneous velocity.

  slope of a graph = change in value of y -axis / change in values of x -axis

  comparing both the equations

    change in value of y -axis = change in position

  change in values of x -axis = time taken

so position values should be on the y axis and time values should be on the x axis.

distance on the y-axis and time on the x-axis.

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

the answer is 100. i just did this lesson and got a 100% on it. : )
