Pls help I’m failing Two identical beakers with exactly the same amount of warm water were prepared. The list
beaker was allowed to cool by sitting in a classroom with an air temperature of 23°C. The
second beaker was placed in a large bucket of ice water at 0°C. The temperature of each was
measured every minute for 45 minutes. The data are shown below.

Which of the following situations is impossible? a) an object has velocity directed east and acceleration directed east. b) an object has zero velocity but non-zero acceleration. c) an object has constant non-zero velocity and changing acceleration. d) an object has velocity directed east and acceleration directed west. e) an object has constant non-zero acceleration and changing velocity.

Will mark brainliest! asap! ! 16) which of the clouds shown would indicate a possible future rain storm? a) b) c) d)

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?
