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

dec 23, 2016 - a load of bricks weighing 680 n a distance of 10 m across a parking lot. if if the worker pushes the cart with a constant force of 209 n, what work= force x distance = 220 n x 10 m = 2200 n.m = 2200 j i don't know where the person got it from, but the initial part, work= force x distance me.

the answer is ampere

the ampere is used to measure electricity. an ampere is a unit of electric current equal. a unit of measure for the flow of current in a circuit. one ampere is the amount of current flow provided when one volt of electrical pressure is applied against one ohm of resistance.
