Answer:
The length of the boomerang is 0.364 m
Explanation:
The moment of inertia is:

Where
md = 0.05 kg
mh = 0.12 kg
r = d/2 = 0.273/2 = 0.1365 m

The length of the boomerang is:

The unconditioned stimulus (UCS) for Tab the dog is: B. The flowers and fence.
<h3>The types of stimuli.</h3>
In Science, the two (2) stimuli that are repeatedly paired in classical conditioning include:
<h3>What is an unconditioned stimulus?</h3>
An unconditioned stimulus can be defined as a stimulus that is capable of naturally triggering a response, before or without any conditioning while it elicit a specific response without learning.
- This ultimately implies that, an unconditioned stimulus leads to an automatic response in a living organism such as a dog.
In this scenario, the unconditioned stimulus (UCS) for Tab the dog is simply the flowers and fence.

Answer:
a. Mass number is the sum of number of protons and neutrons present in the nucleus of an atom.
A = p + n
Charge is a unit of matter that tells how more or less the number of electrons are present as compared to number of protons in an atom. A positive charge means the atom lacks electrons.
Gamma rays are highly energetic electromagnetic rays. They have high penetrating power and are very difficult to shield owing to high energy.
b. The compete nuclear equation is:

This is a alpha decay process because alpha particle which is Helium atom is being produced. Francium is being formed after alpha particle is emitted.
c. The complete nuclear reaction is:

This is a positron emission process where in Rubidium is being formed.
