By definition, we have to:
Where,
p: linear momentum
m: mass of the object
v: object speed
Therefore, knowing the mass of an object and its speed, we have the linear momemtum of the object.
In general, it is useful to calculate the momentum of objects in conservation problems to find the velocity before or after the collision of two objects.
Answer:
The measure of an object's mass and velocity is called momentum.
d. momentum
The radioactive decay is shown in the image attached to this answer
Answer:
Alpha
Explanation:
An alpha decay is said to have occurred when the mass number of the daughter nucleus decreases by four units and the atomic number of the daughter nucleus decreases by two units.
If we look at the equation from left to right, we will notice that the mass number of the daughter nucleus decreased by four units and the atomic of the daughter nucleus number by two units compared to that of the parent nucleus leading to the emission of an alpha particle.
