Answer:
<u>diode</u>: It passes current only in one direction.
<u>resistor</u>: Is the most commonly used electronic element. It is used to limit the electric current flowing in the electronic system.
<u>transistor</u>: It strengthens the current in the receivers, it can also turn it on and off. This element has three tips, which we call the base, collector and emitter.
<u>capacitor</u> : Has the ability to store electricity and can release it when needed. Next to the resistor, it belongs to the most commonly used elements in electronic devices.
Explanation:
Diode is a substance which is half conductor and half insulator that is used to compel the current to flow in only one direction. Resistor is a device which is used for controlling flow of current through circuit. Capacitor is a device which is used as a storage device which provides extra electricity to machine when it is required. Transistor is a device which is used to amplify or switch electronic signals and electrical power.
<u>Answer</u>:
When Uranium-238 decays, it emits 8 Alpha particles and 6 beta particles before finally becoming the stable daughter product. The atomic number and mass number of the daughter product is 92 and 234 respectively.
<u>Explanation</u>:
In the process of decay of Uranium-238, it emits alpha particles, and the resultant product is Thorium-234, which turns into Protactinium-234, and this Protactinium-234 undergoes the beta decay to form the Uranium-234.
As per the question, a stable daughter product is created after the emission of alpha and beta particles, this implies that Uranium-234 is a stable product after the decay of Uranium-238. Therefore, the atomic number is 92 (number of protons) and the mass number is 234 (protons+neutrons) which is also the element of the naming.
It depends on how the test is set up to depends on how revising it will work
