Amachine in an ice factory is capable of exerting 3.31 × 102 n of force to pull large blocks of ice up a slope. the blocks each weigh 1.32 × 104 n. assuming there is no friction, what is the maximum angle that the slope can make with the horizontal if the machine is to be able to complete the task? answer in units of ◦ .

Zeros that follow non-zeros numbers and are also to the right of a decimal point are significant

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.
