Answer:
Radiant and thermal
Explanation:
Electrical and thermal don't make sense because you are not using electricity to light the match. Radiant and nuclear is not right because you are not using nuclear energy to light the match. Nuclear and kinetic isn't right because you are using kinetic and you are not using nuclear energy.
Answer:
A bicycle dynamo is a type of generator attached to a bicycle to produce electricity for the bicycle’s lights. The top of the dynamo touches the tire’s rim, which spins when the bicycle starts moving. Currently, the term dynamo refers to mechanisms that are capable of producing direct current, such as the small devices fitted to bicycles to generate power for the lights.
<h3>___________________________________More Defination :- ______________________________</h3>
Typically, a bicycle dynamo has one or more permanent magnets with coils of wire spinning inside their poles. The device consists of a stationary part called a sator and a rotating part called an armature. When the coil spins in the magnetic field created by the magnets, the magnetic flux begins to change trough the coils, resulting in an electric field that generates the charge carriers through the wire. This process produces an electric current. Small bicycle dynamos attain a low efficiency in converting mechanical motion into electricity. However, there are large machines, such as water wheels, that attain high efficiency under ideal conditions.

Answer: bismuth and nitrogen, because they have the same number of valence electrons
Explanation:
Elements are distributed in groups and periods in a periodic table.
Elements that belong to same groups will show similar chemical properties because they have same number of valence electrons.
The number of valence electrons in Bismuth and nitrogen are 5 and thus thus they will show similar chemical properties and thus belong to the same group.
The atomic masses of elements in a group will differ drastically.
The group number has got nothing to be the isolation year.
Thus bismuth and nitrogen belong to same group because they have the same number of valence electrons
