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.
Hi -
This is known as a <em>scientific law.

Answer:
Yes
Explanation:
Velocity is a vector quantity, meaning it has size and direction, as opposed to speed, a scalar quantity which only has size.
An example is speed may be 30km/h, and an example of velocity is 30km/h East.
Therefore two people can have the same speed and different velocities because they can be traveling in different directions.
For example, you and your friend could be doing shuttles together but you started at one wall and they started at the other, so even though you are running at the same speed, you always have different velocities because they are running in the opposite direction as you.
Hope this helped!
I have done this assignment before so I can tell you the more length that hangs over the table, the less vibration there is due to lack of tension.
Answer:
Explanation:
Recall the formula for linear momentum (p):
which in our case equals 26.4 kg m/s
and notice that the kinetic energy can be written in terms of the linear momentum (p) as shown below:
Then, we can solve for the mass (m) given the information we have on the kinetic energy and momentum of the particle:
Now by knowing the particle's mass, we use the momentum formula to find its speed:
