<h3>What is alpha decay?</h3>
The term alpha decay is the term that is used to describe a type of radioactive decay that involves the evolution of a helium nucleus. In this case the question is incomplete but I will try to paint a general picture of alpha decay.
The general equation for an alpha decay will produce a daughter nucleus that has an atomic mass less by four units and atomic number that is less by two units.

Answer:
Explanation:
The hand throwing ball moves on a circular path having radius r = .55 m
mass of ball m = .19 kg
velocity v = 70 mph
= 70 x 1600 / 60 x 60
= 31.11 m /s
centripetal force
= mv² / r
= .19 x 31.11² / .55
= 334.34 N
Answer:
17m/s
Step by step explanation:
Using g= 10m/s²
Maximum H = (u²sin²theta) /2g
12 = u² sin²(45)/2(10)
12 = u²(0.72)/20
0.72 u²= 240
u² = 240/0.72 = 333.33
Initial velocity = 18.3m/s
Its like the weather man. They are the people you see on the news that use radars ect. To predict the weather.
Hope that helps?
Answer:
Aluminium
Explanation:
Aluminium has the least resistance since It has 3 free electrons per atom. Its resistivity is low compared to other metals provided in the choices (gold, nichrome, tungsten). Low resistivity of metals means a high conductance of the metal referred to.
