What two things do circuits have to have for them to work

Chemistry
1 answer:
Kisachek [45]3 years ago
4 0

Two things that must be in circuits to make them work are a conductor and a voltage source.

<u>Explanation:</u>

There are tow main parts that helps all electric circuits to work. They are a conductor and a voltage source. Some of the other parts of circuits includes,switches and bulbs. The working of an electrical circuit is same as that of the human circulatory system. The blood is taken to all parts of human body with the help of the blood vessels in a circulatory system.

Same thing happens with an electrical circuit. This is responsible in taking current to all parts of an electrical system. In an electrical circuit electricity will flow from the voltage of high to low. A path should be there for conducting the electric power.

Answer:

<h2>9000 N</h2>

Explanation:

The force acting on an object given it's mass and acceleration can be found by using the formula

force = mass × acceleration

From the question we have

force = 900 × 10

We have the final answer as

<h3>9000 N</h3>

34kurt

Answer:

This is a chemical change because it has been lit on fire. When it is lit on fire, the fire has been made, heat has been made, and gasses produced from the fire have also been made. Because this introduces new matter to the pictures, it is a chemical reaction.

Which of the following forms a new substance? melting, evaporating, freezing or burning
Slav-nsk [51]
It would be burning be cause when you freeze, evaporate, or melt anything it is just changing how fast the atoms are moving . Think of it like water, ice, and steam, they are all the same thing but in different forms because of melting, evaporating,and melting. Burning is breaking it down.

Airida [17]

Answer:

d. each of the above (A, B, and C) occurs.

Explanation:

When an ionic species dissolves in water , the ionic compound dissociates into cation and anion , and the cation interacts with the negative end of the water molecules , and the anion interacts with the positive end of the water molecule .

During the process of dissolution , the interaction between , solvent - solute overcome the interaction between solute - solute molecules .

Hence , From the question , all the statement given are correct .

The activation energy for a reaction is changed from 184 kJ/mol to 60.5 kJ/mol at 600. K by the introduction of a catalyst. If t
Ahat [919]

Answer:

The catalyzed reaction will take 1,41 s

Explanation:

The rate constant for a reaction is:

k = A e^{-\frac{Ea}{RT}}

Assuming frequency factor is the same for both reactions (with and without catalyst) it is possible to obtain:

{\frac{k1}{k2}} = e^{-\frac{Ea_{2}-Ea_{1}}{RT}}

Replacing:

{\frac{k1}{k2}} = e^{-\frac{60,5kJ/mol-184kJ/mol}{8,314472x10^{-3}kJ/molK*600k}}

{\frac{k1}{k2}} = 5,64x10^{10}

That means the reaction occurs 5,64x10¹⁰ faster than the uncatalyzed reaction, that is 2537 years / 5,64x10¹⁰ = 4,50x10⁻⁸ years. In seconds:

4,50x10⁻⁸ years×\frac{365days}{1year}×\frac{24hours}{1day}×\frac{3600s}{1hour} =<em> 1,41 s</em>

I hope it helps!
