The type of radioactive decay that has a positive charge is alpha particles, which are positively charged.
<h3>What is radioactive decay?</h3>
The expression radioactive decay makes reference to the emission of ionizing radiation for a given atom, thereby an unstable atom may lose energy by releasing radiation.
Alpha particles are specific atomic particles consisting of 2 protons (positive charge) and also 2 neutrons that share chemical bonds.
In conclusion, the type of radioactive decay that has a positive charge is alpha particles, which are positively charged.

#SPJ1
The average speed is 8 miles
Answer: Speed = 4 m/s
Explanation:
The parameters given are
Mass M = 60 kg
Height h = 0.8 m
Acceleration due to gravity g= 10 m/s2
Before the man jumps, he will be experiencing potential energy at the top of the table.
P.E = mgh
Substitute all the parameters into the formula
P.E = 60 × 9.8 × 0.8
P.E = 470.4 J
As he jumped from the table and hit the ground, the whole P.E will be converted to kinetic energy according to conservative of energy.
When hitting the ground,
K.E = P.E
Where K.E = 1/2mv^2
Substitute m and 470.4 into the formula
470.4 = 1/2 × 60 × V^2
V^2 = 470.4/30
V^2 = 15.68
V = square root (15.68)
V = 3.959 m/s
Therefore, the speed of the man when hitting the ground is approximately 4 m/s
A graph. This can be called a graph. A graph is the answer.
The best answer to the question '<span>What does an alpha particle consist of?' would be letter c. An alpha particle consists of 2 protons and 2 neutrons. It is a particle that has no electrons and balances out the positively charged protons. </span>
