What is a series circuit? (Definition)

1 answer:

3 0

<span>A series circuit is a circuit in which resistors are arranged in a chain, so the current has only one path to take. The current is the same through each resistor. The total resistance of the circuit is found by simply adding up the resistance values of the individual resistors:</span>

Which phase of matter consists of particles that vibrate only?

bearhunter [10]

Answer: Solids

Explanation: Solids have very little movement and the particles have barely enough movement to vibrate. We can't see it but the particles are indeed vibrating. Solids have the least amount of kinetic energy which is moving energy.

A car has a distance between axles of 6.2 m and a center of mass located 2.2 m from the front axle. What is the

NARA [144]

Answer:

The correct option is C

Explanation:

From the question we are told that

The distance between axles of the car is $d_a = 6.2$

The position of the car's center of mass is $D = 2.2 \ m \ in \ front \ of \ the \ axel$

Now we can evaluate the distance of the center of mass to the rear axle as follows

$k = d_a - D$

substituting values

$k = 6.2 - 2.2$

$k = 4 \ m$

assuming the car is at equilibrium, taking moment about the center of mass

$W_{front \ axle} * D - W_{rear \ axle} * k = 0$

=> $W_{front \ axle} * D = W_{rear \ axle} * k$

=> $\frac{W_{front \ axle}}{W_{rear \ axle} } = \frac{k}{D}$

substituting values

$\frac{W_{front \ axle}}{W_{rear \ axle} } = \frac{4}{2.2}$

$\frac{W_{front \ axle}}{W_{rear \ axle} } = 1.81$ Note [ $W_{front \ axle}$ is the front axle weight and

$W_{rear \ axle}$ is the rear axle weight ]

Identify the solute and solvent in a solution made of 15g of oxygen and 5g<br> of helium

Marrrta [24]

Taking into account the definition of solvent and solute, helium is the solute and oxygen is the solvent.

<h3>Definition of solute and solvent</h3>

The solution is a homogeneous mixture of two or more components that have the same chemical and physical properties in a single phase. A solution is made up of two main components: the solute and the solvent.

That is, the solute and the solvent are the components of a chemical solution, that is, of a homogeneous mixture that occurs when one or more substances are dissolved in another substance.

The solute is the substance that dissolves in a solution. In solution, the solute is usually found in a lower proportion than the solvent.

Solvent is the substance in which a solute dissolves, resulting in a chemical solution. Generally, the solvent is the component that is found in the highest proportion in the solution. It will always be the solvent who will determine the state of the matter that will have the solution.

<h3>Solute ans solvent in this case</h3>

In this case, you consider that the solute is the component in less quantity and the solvent is the major component.

You know that a solution made of 15 g of oxygen and 5 g of helium. Then, helium is the solute and oxygen is the solvent.

Does uranium use turbines<br> i promise to mark brainliest

Pie

In a nuclear reactor the uranium fuel is assembled in such a way that a controlled fission chain reaction can be achieved. The heat created by splitting the U-235 atoms is then used to make steam which spins a turbine to drive a generator, producing electricity. So I am guessing Yes it does.
