Scientists are trying to determine the effect of mass on the force of gravity between two objects. in this experiment, then scientists use the following procedure: 1) place two large, empty barrels exactly 1m apart. 2) measure the gravitational force between the two barrels and record in data table. 3) add 10kg of water to each barrel. 4) measure the gravitational force between the two barrels and record in data table. 5) repeat steps 3 & 4 until the barrels are completely full of water. 6) create a graph of gravitational force vs mass from the data collected. what should the graph from step 6 look like?

Acyclotron is used to produce a beam of high-energy deuterons that then collide with a target to produce radioactive isotopes for a medical procedure. deuterons are nuclei of deuterium, an isotope of hydrogen, consisting of one neutron and one proton, with total mass 3.34×10−27kg. the deuterons exit the cyclotron with a kinetic energy of 6.40 mev .a-what is the speed of the deuterons when they exit? b-if the magnetic field inside the cyclotron is 1.25 t, what is the diameter of the deuterons' largest orbit, just before they exit? c-if the beam current is 350 μa how many deuterons strike the target each second?
