Answer:
P = 24.32 W
Explanation:
The question is, "Two resistors 5 Ω and 10 Ω are connected in parallel with a 9 V power supply. Calculate the output power of the power supply.".
The voltage of the power supply, V = 9 V
Resistor 1, R₁ = 5 Ω
R₂ = 10 Ω
The equivalent of parallel combination of resistors is given by :
The power of the output is given by :
So, the output power is equal to 24.32 W.
The unknown metal with a mass of 39.27 g is potassium with the symbol K.
The mass of an atom is due to protons and neutrons present in it.
The protons and neutrons are together present in the nucleus of an atom.
The mass of any element is given by its mass number whose formula is
Mass Number = Number of protons + Number of neutrons
In the given case 39 = Number of protons + Number of neutrons
The only element of the periodic table which satisfies the above equation is potassium because it has 19 protons and 20 neutrons.
Thus, the unknown metal with a mass of 39.27 g is potassium with the symbol K.
