If the amount of force applied to the balloon at the end of the string keeps increasing, what is the likely outcome? Group of answer choices

a. The balloon will eventually reach escape velocity and fly off the string.

b. The balloon will be drawn inward toward the clothespin.

c. The balloon will burst and spew water everywhere

d. The balloon will collapse and become even smaller.

Cyclotrons are widely used in nuclear medicine for producing short-lived radioactive isotopes. these cyclotrons typically accelerate h- (the hydride ion, which has one proton and two electrons) to an energy of 5 mev to 20 mev. this ion has a mass very close to that of a proton because the electron mass is negligible—about 1 2000 of the proton’s mass. a typical magnetic field in such cyclotrons is 1.9 t. (a) what is the speed of a 5.0-mev h-? (b) if the h- has energy 5.0 mev and b = 1.9 t, what is the radius of this ion’s circular orbit?
