Ken Runfast is the star of their cross-country team. During a recent morning run, Ken averaged a speed of 5.8 m/s for 770 seconds. Ken then averaged a speed of 6,10 m/s for 425 seconds.
Determine the total distance which Ken ran during his jog.

According to newtons universal law of gravitation, which would change the parh of the ball so it traces out widest curved path possible?

Explain what happens at the saturation point when adding salt to water at room temperature.

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?
