Answer:
C.) perpendicular
Explanation:
A particle with an electric charge experiences the maximum deflecting force when it is positioned perpendicular to the magnetic field.
Answer:
77.14 atm of pressure should be of an acetylene in the tank.
Explanation:
According to reaction, 2 moles of acetylene reacts with 5 moles of oxygen.
Moles of oxygen=
Moles of acetylene =
Volume of large tank with oxygen gas,
Pressure of the oxygen gas inside the tank =
..[1]
Volume of small tank with acetylene gas ,
Pressure of the acetylene gas inside the tank =
..[2]
Considering both the gases having same temperature T, [1]=[2]
77.14 atm of pressure should be of an acetylene in the tank.
A welding torch produces a flame by burning of acetylene fuel then energy released from the acetylene fuel is then used to melt a metal, so transformation of chemical energy into thermal energy takes place.
<h3>What is transfer of energy?</h3>
Energy neither can be produced nor destroyed but it only transfers from one form to other form.
In the question it is given that, burning of acetylene produces energy and this produced energy is a type of chemical energy and then this is used as a thermal energy for the melting of metal.
So conversion of kinetic energy to potential energy, thermal energy to electromagnetic energy and potential energy to chemical is wrong.
Hence transformation of chemical energy into thermal energy takes place.

Answer:
Co(cobalt) is the answer
Explanation:
Cobalt is a chemical element with the symbol Co and atomic number 27. Like nickel, cobalt is found in the Earth's crust only in chemically combined form, save for small deposits found in alloys of natural meteoric iron. The free element, produced by reductive smelting, is a hard, lustrous, silver-gray metal.
