~Hello there!
Your questions: The rare Earth elements include ___________________.
Your answer: There are many Earth elements but some of the rare elements are the following as mentioned:
1) Gadolinium
2) Holmium
3) Yttrium
4) Promethium
5) Samarium.
Note: These are some of the rare Earth elements, there are MANY rare elements that are found in Earth.
Any questions ^?
Happy Studying!

Answer:
Gamma radiation
Explanation:
There are three types of ionizing radiation:
- Alpha radiation: it consists of alpha particles, which are nuclei of helium (so, they contain 2 protons and 2 neutron) --> therefore, they have a net charge of +2 (given by the positive charge of the two electrons)
- Beta radiation: it consists of electron (in case of beta-minus radiation) or positrons (in case of beta-plus radiation). Therefore, in both cases the radiation is electrically charged: charge -e for the electrons, charge +e for the positrons
- Gamma radiation: it consists of high-energy photons. Since photons are electrically neutral, gamma radiation has no electric charge associated with it.
Answer:
Explanation:
A uniform circular motion is an example of accelerated motion.
When an object is moving in a uniform circular motion, there is a centripetal force acting towards the centre of the circular path and then a centrifugal force is also acting away from the centre of the circular path. The magnitude of the centripetal force and the centrifugal force is same but the direction is opposite to each other. So, it is explained by the Newton's third law.
