Alpha decay is one process that unstable atoms can use to become more stable. During alpha decay, an atom's nucleus sheds two protons and two neutrons in a packet that scientists call an alpha particle. Since an atom loses two protons during alpha decay, it changes from one element to another.

Explanation:
#nerd
Explanation:
The given data is as follows.
= (4 + 273) K = 277 K
= (22 + 273) K = 295 K
= 21.2
Formula to calculate activation energy will be as follows.
3.05 =
= 115116.914 J/mol
or = 115.116 kJ/mol
Thus, we can conclude that overall activation energy (kJ/mol) of the process is 115.116 kJ/mol.
Answer:
The force of gravity between the Earth and the school bus is more on a school day than on a weekend
Explanation:
The force of gravity, F, is the attractive force that holds objects in place on the Earth's surface
The force of gravity attracting the bus of mass m to the Earth of mass M having a radius of , can be presented by the following equation;
Which shows that the force increases as the mass of the bus increases
Since the school bus mass on a school day when carrying Pupils is mare than the mass of the bus in the weekend when the bus is empty, the force of gravity between the Earth and the school bus is more on a school day than on a weekend.
