After a radioactive atom decays, it is the same element that it was before with no measurable change in mass. Which kind of decay has occurred, and how do you know? alpha decay because alpha particles have no mass beta decay because this kind of decay cannot change one element into another alpha decay because it creates a new isotope of the same element gamma decay because photons have no mass.

How do I calculate the equivalent resistance?

A uniform Capillary tube closed at one end Contain dry air trapped by a thread of mercury 8.5x10 m long when the tube was held horizontally, the length of the air Column 5.0X10^2 Wher it held verti cally with the closed end downward the length was 4.5x10^2m Determine the value of atmospheric pressure take g=10m/s, density of mercury (1.36×10^4kg/m) ​
