for a moving object, the force acting on the object varles directly with the object's acceleration. when a force of 25 n acts on a certain object, the acceleration
of the object is 5 m/s. if the acceleration of the object becomes 9 m/s', what is the force?

The figure shows triangle def and line segment bc, which is parallel to ef: triangle def has a point b on side de and point c on side df. the line bc is parallel to the line ef. part a: is triangle def similar to triangle dbc? explain using what you know about triangle similarity. part b: which line segment on triangle dbc corresponds to line segment ef? explain your answer. part c: which angle on triangle dbc corresponds to angle f? explain your answer. asap
