Ahot air balloon is rising upward with a constant speed of 2.50m/s. when the balloon is 3.0 m above the ground, the balloonist drops a compass over the side of the balloon. how much time elapses before the compass hits the ground?
ps. do you mind explaining why you chose a certain formula or why you plugged in certain values?

Which force is most responsible for binding together an atom's protons and neutrons? electrostatic gravitational nuclear magnetic

Velocity is a description of both speed and direction, therefore it - a vector - a force arrow - the same as acceleration - a magnitude

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.
