A 1.75-kg picture frame is hung on the wall by means of a horizontal string on the back of the frame. The string is attached to screws on the sides of the frame, which are separated by a distance of 37.0 cm. When hung from a nail on the wall, the string is
displaced at its center by a vertical distance of 4.00 cm. What is the tension T in the string?

Mass (kg) force (n) 5 25 10 50 15 75 20 100 a student was trying to find the relationship between mass and force. he placed four different masses on a table and pulled them using a spring scale. the table shows the different masses used in the experiment and the force required to pull each mass. the student concluded that more force was required to pull heavier objects. what comment would you make regarding his conclusion? a) no clear relation can be observed between mass and force from the data. b) there is a direct proportion between the mass and force listed in the table. c) gravity should have been taken into account while performing the experiment. d) there is an inverse proportion between the mass and force listed in the table.
