<h2>
Answer: C. 7.67 W </h2>
Explanation:
Firstly, we are told the three resistors are <u>connected in parallel</u>, this means we have to use the following equation to find the total resistance of the circuit:
(1)
Where: , ,
Solving (1):
(2)
(3)
(4) This is the total resistance of the circuit
On the other hand, the total power of this circuit is given by the following equation:
(5)
Where is the total voltage of the circuit.
Solving:
(6)
Finally:
(7) This is the total power of the circuit in Watts (W)
Answer
Hi,
In a chemical equation, chemicals that react are the reactants, while chemicals that are produced are the products/by products. Both sides of the equation must be balanced.
Explanation
When writing a chemical equation, reactants reacts to produce products. For example in the equation for formation of water, hydrogen combines with oxygen as 2H₂ +O₂→2H₂O where the first part before the arrow represent the reactants and the next part after the arrow are the products. Reactants are on the left where as products are on the right.Coefficient 2, in this cases is used for balancing the equation.
Good luck!
The strongest of the natural forces is Strong Nuclear, followed by Electromagnetic, then Weak Nuclear and lastly Gravitational.
So from weakest to strongest: gravitational --> weak nuclear --> electromagnetic --> strong nuclear
