for a moving object, the force acting on the object varies directly with the object acceleration, when a force of 20N acts on a certain , the acceleration of the object is 2m/s^2, if the force is changed to 90N what wil be the acceleration of the object

The construction of copying qpr is started below. the next step is to set the width of the compass to the length of ab. how does this step ensure that a new angle will be congruent to the original angle? by using compass take the measures of angle and draw the same arc according to it.
