Answer:

3 Amperes

Explanation:

This is an example of a parallel and series resistor. The first set of resistors are in parallel(the 6 and 3 ohms).

The total resistance of these two resistors can be solved through the following formula:

$\frac{1}{R_{2} } +\frac{1}{R_{3} } =\frac{1}{R_{Equal} }$

*This is for any resistors in parallel

Plugging in the numbers, we find that an equivalent resistor has a resistance of 2 ohms. Adding this to the 4 ohms, we get that there a total of 6 ohms of resistance with the resistors in this circuit.

Using Ohms law:

I = V/R

I = 18 V/ 6 Ohms

I = 3 Amperes.

ser-zykov [4K]

What condition alone is necessary so that the final kinetic energy of the system is zero after the collision?

<u>Option(a). </u>The objects must have initial momenta with the same magnitude but opposite directions.

What is a momentum?

In Newtonian mechanics, linear momentum, translational momentum, or simply momentum is the product of the mass and velocity of an object.
It is a vector quantity, possessing a magnitude and a direction.
If m is an object's mass and v is its velocity (also a vector quantity), then the object's momentum p is :p=mv.
In the International System of Units (SI), the unit of measurement of momentum is the kilogram metre per second (kg⋅m/s), which is equivalent to the newton-second.

Nonmetals are usually _____ which means that they evaporate easily.

steposvetlana [31]

<span>The answer to this question is that non metals are volatile. Volatile means evaporating easily. Non metals have the characteristics and properties of being brittle and poor conductors of heat and electricity. Non metals are also good oxidizing agents and physically they may be in liquid, solid or gas state. Examples of non metals are carbon, sulfur, argon, neon, and hydrogen.</span>

What is latent heat? Group of answer choices Energy released when water evaporates. Energy hidden in water vapor in the air. Ene

Andrews [41]

Answer:

Energy absorbed or hidden when water evaporates

Explanation:

The heat that is required to make a phase change is known as latent heat.

A phase change occurs when matter changes state. For example from solid to liquid, from liquid to gas, among others.

When changing from liquid to gas (for example when water evaporates), the heat necessary for this to happen is called latent heat of vaporization. The word latent means hidden, because a change in temperature is not perceived during the phase change, even when heat is being added, thus it is said that the heat is hidden or latent.

So the answer is:

Energy absorbed or hidden when water evaporates.

*Another type of latent heat is the latent heat of fusion, which is when a solid becomes liquid.

krok68 [10]

Answer:

The Resultant Induced Emf in coil is 4∈.

Explanation:

Given that,

A coil of wire containing having N turns in an External magnetic Field that is perpendicular to the plane of the coil which is steadily changing. An Emf (∈) is induced in the coil.

To find :-

find the induced Emf if rate of change of the magnetic field and the number of turns in the coil are Doubled (but nothing else changes).

So,

Emf induced in the coil represented by formula
