A brick with length 0.2 m and width 0.1 m rests on the ground. As it rests, it is exerting a 45 N force. (Note: These numbers are not realistic.) Calculate the
pressure exerted by the brick onto the ground (try using Equatio). Show all your
work and end with a concluding statement. (Hint: Look at the example calculation
in my slides for help. Be aware, though, that, to get the answer, there is an extra
step to add here). *

Many radioactive atoms that have large masses undergo radioactive decay by releasing a particle that is identical to a helium-4 nucleus. what changes in the original atom are expected as a result of this natural phenomenon? the atomic number and the mass number will decrease. the atomic number and the mass number will increase. the atomic number will increase, and the mass number will decrease. the atomic number will decrease, and the mass number will increase.
