1. 20 kg*mass of the earth
2. 10 m/s2
3. 2.3 m/s2
Hope this helps!
number 9 is : Organized Data is a customizable information product versioning and management system used to track and store document, images and other products or information
Wave speed = frequency x wavelength
= 100 x 0.3
= 30 m/s.
Hope this helps!
I believe it would be 7.731. x 10^5? That is if they want you to evaluate.
1. The atomic number deceases by one and the atomic mass is unchanged - β⁺/positron emission. In this a proton is converted to a neutron, hence no net change in mass. Since a proton is converted to neutron, the daughter nuclide's proton number /atomic number decreases by 1. Then atomic number decreases by 1 and no change in mass.
2.the atomic number decreases by two, and the atomic mass decreases by four - alpha decay / ⁴₂α. alpha particles have 2 neutrons and 2 protons. Since 2 protons and 2 neutrons are emitted, the mass of the nuclide decreases by 4. Since 2 protons have been emitted, this results in atomic number decreasing by 2.
3.<span>the atomic number increases by one, and the atomic mass remains unchanged. - </span>β⁻ beta decay. In this type of decay - beta decay , a neutron is converted to a proton, therefore no net change in mass. Since a proton is formed, atomic number increases by 1. Therefore atomic number increases by 1 and no change in mass.
