Tính áp suất tổng cộng do khí quyển và nước tác dụng lên các sinh vật biển ở độ sâu 12 m ( theo đơn vị Pa và atm). Biết áp suất khí quyển trên mặt nước là 1 atm và trọng lượng riêng của nước là 10000N/m3

Although longitudinal waves can travel through all media types what is the disadvantage of this type of wave transmission? a) he efficiency of he wave transmission is greatly diminished as the media becomes less dense b) the oscillation of one set of particles has a huge impact on neighboring particles c) particles become too close together as they bump into each other making it more likely to hit other particles down the line

Daughter element the new element produced along with a decay particle in a nuclear transmutation 2. half-life the substance that decays in a nuclear transmutation 3. parent element the change of one chemical element into another by nuclear decay or radioactive bombardment 4. transmutation the time required for the decay of one-half of the atoms in a sample of radioactive material
