What are the advantages of parallel circuits? Check all that apply

Physics

Bezzdna [24]3 years ago

Answer:

If one bulb goes out, other bulbs stays lit.

If there is break in one branch of the circuit, current can still flow through other branches.

Parallel circuits are simple to design and build.

Explanation:

In parallel circuits all the components and resistors are connected to common terminal or common supply.

So here if we disconnect one of the branch of the circuit then it will not affect the other branches of the circuit so it will not affect the current of other branches.

So here it is very easy to build a parallel circuit and if one of the branch of the circuit goes out then it will not affect the other branches.

As charges move in a closed loop, they
mamaluj [8]

As charges move in a closed loop, they gain as much energy as they lose.

<h3>What is principle of conservation of energy?</h3>
  • According to the principle of conservation of energy, in a closed or isolated system, the total energy of the system is always conserved.
  • The energy gained by the particles or charges in a closed system is equal to the energy lost  by the charges.

Thus, we can conclude the following based on principles of conservation of energy;

  • As charges move in a closed loop, they gain as much energy as they lose.

An object has 1200 J of gravitational potential energy when it is dropped. Right when the object hits the ground how much kineti
Fittoniya [83]

Answer:

The kinetic energy is 1200 J

Explanation:

The Principle of Conservation of energy states that "energy is neither created nor destroyed, it is transformed".

This means that energy can be transformed from one form to another, but the total amount of energy always remains constant, that is, the total energy is the same before and after each transformation.

The mechanical energy of a body or a physical system is the sum of its kinetic energy and the potential energy. According to the Principle of Conservation of Energy for mechanical energy, the total mechanical energy that a body possesses is constant at every instant of time.

Since mechanical energy is equal to the sum of kinetic energy and gravitational potential energy that a body possesses, the only way to stay constant is that:

  • when the kinetic energy increases the gravitational potential energy decreases,
  • when gravitational potential energy increases, kinetic energy decreases.

Due to the Principle of Conservation of Energy you can say that the gravitational potential energy is converted to kinetic energy.  So Gravitational potential energy at the top = kinetic energy at the bottom

<u><em>The kinetic energy is 1200 J</em></u>

6. Aaron will run from home at y mph and walk back at x mph. how much distance does he need to travel to spend a total of t hour
Kisachek [45]

Answer:

Total distance, d=\dfrac{xyt}{(x+y)}

Explanation:

It is given that,

Speed of Aaron from home is y mph and walk back at x mph. Let t is the total time he spend in walking and jogging. Let d is the distance covered.

We he moves from home to destination, time is equal to, \dfrac{d}{x}

Similarly, when he move back to home, time taken is equal to \dfrac{d}{y}

Total time taken is equal to :

\dfrac{d}{x}+\dfrac{d}{y}=t

d(\dfrac{1}{x}+\dfrac{1}{y})=t

d=\dfrac{t}{(\dfrac{1}{x}+\dfrac{1}{y})}

d=\dfrac{xyt}{(x+y)}

So, the distance he speed in walking and jogging is \dfrac{xyt}{(x+y)}. Hence, this is the required solution.

You need to push a heavy box across a rough floor, and you want to minimize the average force applied to the box during the time
7nadin3 [17]

When pushing the body it is necessary to break the frictional force generated by the floor. Once this frictional force is overcome, the body will begin to move. Ideally, if a constant velocity is maintained or close to this value, the acceleration that will be exerted will tend to be zero and therefore, by Newton's second law the value of the Force will also tend to minimum values.

Remember that this law tells us that

F= ma

F= m \frac{\Delta v}{t}

Therefore the best strategy is A. keep pushing the box forward at a steady speed
