Which type of circuit has two or more branches for the current to flow through?

1 answer:

3 0

Hello,

The answer is A. Parallel circuit.

Unlike a series circuit, these circuits allow currents to flow through multiple branches. An open circuit is an electrical current that is not valid, therefore there will be no current flow. A combination circuit, I believe, <span>is a </span>circuit<span> that is a blend of series paths and parallel paths.

The smooth muscle in the wall of the bladder when stretched triggers the micturition reflex (urination).

<h3>What is a Bladder?</h3>

This is defined as a lined layers of muscle tissue that stretch to hold urine in organisms.

In older people the elasticity of the bladder is reduced which is why it makes it harder for them to hold urine for a long time.

Select the phrases that correctly describe density. Select one or more: a. Density is a physical property. b. Density determines

Serga [27]

Answer:

Options (A), (B), (D), and (E).

Explanation:

Density is a physical property that describes the relationship between mass and volume. This property shows whether an object will float or it will get sink. The density of substances changes with the changing temperature, as both are inversely proportional to each other.

Mathematically, density can be written as,

Density = $\frac{mass}{volume}$

ρ = $\frac{m}{v}$ , Where, ρ = density, m = mass, v = volume

Thus, the correct answers are options (A), (B), (D), and (E).

Boxes A and B are in contact on a horizontal, frictionless surface. Box A has mass 21.0 kg and box B has mass 8.0 kg. A horizont

vfiekz [6]

Answer:

2.75 N

Explanation:

Given that,

Box A has a mass 21.0 kg and box B has a mass 8.0 kg.

A horizontal force of 100N is exerted on box A.

Let a be the acceleration of the system. Using second law of motion,

$F=(m_A+m_B)a\\\\a=\dfrac{F}{(m_A+m_B)}\\\\a=\dfrac{10}{(21+8)}\\\\a=0.344\ m/s^2$

Now applying Newton's second law to box B. So,

$F_A=m_Ba\\\\=8\times 0.344\\\\=2.75\ N$

So, 2.75 N is the force that box A exerts on box B.

Which identifies a machine that converts mechanical energy into electrical energy?

yKpoI14uk [10]

The answer is the option c. generator. Generator is a machine that converts mechanical energy into electricity. The way it is made is because the mechanical movement may be transformed in rotation of magnets placed inside a coiled wire, and this induces the movement of electrons through the coiled wire. As you know electricity is the flow of electrons.
