Step-by-step explanation:
if 4 men did the job in 12 days , then each of the 4 men worked for 12 days , which means they worked for 4*12=48 days , so the job takes 48 work days to complete. If all men work at the same rate, then these other 6 will complete the job in
Therefore, it’ll take the group of 6 men 8 days to complete the job.
The "rate" at which something travels can be referred to as velocity.
V = displacement / time
So going with the wind, Vp + Vw = 1800 / 3.6 = 500 mph
Going against the wind, Vp - Vw = 1800 / 4 = 450 mph
Vp = 500 - Vw
Vp = 450 + Vw
500 - Vw = 450 +Vw
2Vw = 50
Vw = 25 mph
Vp = 475 mph
The type of Nuclear decay that is described where Gold undergoes transmutation is given as 185/79 Au → 181/77 Ir + 4/2 He, it is called Alpha Decay.
<h3>
What are the characteristics of Alpha Decay?</h3>
An Alpha Decay can be described as a form of radioactive or Nuclear decay where the atomic nucleus releases an alpha particle (also known as Helium Nucleus).
It then converts into a nucleus that is atomic with an atomic number of two and a mass number of four.
Alpha Decay is usually trigged for two key reasons:
- An unstable nucleus; and
- excessive protons.
