Work done by force is given by formula
now here work done against friction is given so force of friction here is
It moved by three corridors with each measures
so total distance will be
now from above formula of work done we will say
so above is the work done to move three corridors
Answer:
After a nucleus with 85 protons undergoes alpha decay, it has 83 protons.
Explanation:
In an alpha particle there are two protons
In the given substance's nucleus, there are total of 85 protons
After the decay, the proton number reduce
The current proton number after decay is
85 -2 = 83
After a nucleus with 85 protons undergoes alpha decay, it has 83 protons.
