nitrous oxide, N2O?

1.one nitrogen atom and two oxygen atoms

2.two nitrogen atoms and one oxygen atom

3. one nitrogen atom and one oxygen atom

4. two nitrogen atoms and two oxygen atoms

Answer:

Please show the warning's

Explanation:

The warning refers to the chemical property of the material or object that is flammable.

A chemical property is a feature that pertains to how a component, such as an ingredient or a compound, can alter as a result of a reaction. Due to bonding and other atomic structural characteristics, a substance develops these qualities as a result of its chemical identity.

Tactile or visual changes may occur in conjunction with chemical qualities. Chemical reactions commonly involve popping, fizzing, or the release of brilliant light. The emission of heat may also be a sign of a chemical reaction or chemical conversion that is taking place. Because the connections in the atomic structure are changing or breaking, these sensory clues appear.

Therefore, the warning refers to a chemical property of the material is flammable or combustible.

Explanation:

Acceleration is the rate of change of velocity. Usually, acceleration means the speed is changing, but not always. When an object moves in a circular path at a constant speed, it is still accelerating, because the direction of its velocity is changing.

The Correct Answer is

The U.S. Constitution says powers not given to the federal government belong to the states.

Explanation:

In the paragraph, Jefferson states defending the rights of states is one of the fundamental, or most significant, policies of our administration. Did that get you to remember the Tenth Amendment? It restrains the authority of the central government, defending the rights of states. It states that the central government only has the authorities listed in the Constitution. Unlisted authorities belong to the states.

Answer:

D

Explanation:

Answer:

W = 1590 J

Explanation:

We could use the formula of potential energy to find work as both have the same units,

                    W = mgh

since weight = mg so,

                     Work = weight x height

                               = 530 x 3

                               = 1590 J

Answer:

The work will be 1590 J

since the formula is W = F x D so I cancel the time

Explanation:

Given:

(Force) F = 530N

(Distance)D = 3m

Unknown:

W or Work

Formula and Solution:

W = F x D

W = (530N) (3m)

Final Answer:

W = 1 590 N·m or simplify as 1590 J

Answer:       false

Explanation: on edg

It is false that reviewing old tests and quizzes will not help you determine what will be on a test because teachers don’t like to give students hints about what could be on future tests.

A test review verifies whether or not the modifications made to the code, data, or documentation are accurate.

In other words, it is an evaluation of the degree to which the stated goals have been attained that has been done at a set period.

Exam analysis might provide insights that can help you become a more self-sufficient learner.

You can improve your performance the next time you are tested by revising your strategy after reviewing returned examinations to learn why you made mistakes.

Thus, the given statement is false.

Answer:

They contain loosely packed atoms.

Explanation:

Note: I'm assuming the data 77.3 is the mass of the crate.

Answer:

[tex]\mu_s =0.36[/tex]

Explanation:

The coefficient of static friction, called \mu_s is the ratio between the force needed to start moving an object above a rough surface (Fr), and the normal force the surface exerts on the object (N).

[tex]\displaystyle \mu_s =\frac{Fr}{N}[/tex]

The normal force is numerical equivalent to the weight of the body if no other external forces are acting.

[tex]N=m\cdot g[/tex]

The mass of the crate is m=77.3 Kg, thus its weight and normal force is:

[tex]N=77.3\ kg\cdot 9.8\ m/s^2[/tex]

[tex]N= 757.54\ Nw[/tex]

Now we calculate the coefficient:

[tex]\displaystyle \mu_s =\frac{275\cancel{N}}{757.54\cancel{N}}[/tex]

[tex]\boxed{\mu_s =0.36}[/tex]

Answer:

Explanation:

Answer:

h = 1.8 m

Explanation:

The initial velocity of the glove, u =- 6 m/s

We need to find the maximum height of the glove. Let it is equal to h. Using equation of kinematics. At the maximum height v = 0

[tex]v^2-u^2=2ah[/tex], h is the maximum height and a = -g

[tex]0^2-(6)^2=2\times (-10)\times h\\\\h=\dfrac{36}{20}\\\\h=1.8\ m[/tex]

Hence, it will go up to a height of 1.8 m.

Answer:

the nails

Explanation:

The force of the nail pushing in the opposite direction. The correct option is option D among all the given options.

A force in physics is an effect that changes the velocity of a mass-moving object, causing it to accelerate from rest, for example. It is a vector quantity since it can be a push or even a pull and always has magnitude and direction.

The head of a hammer is often made of steel. This makes the head heavy, which helps create a strong force for driving nails. Steel is also strong. The head of a hammer must be strong to resist the force of the nail pushing in the opposite direction.

Therefore,  the force of the nail pushing in the opposite direction. The correct option is option D.

wavelength is denoted by the letter lambda it is equal to the speed (v) of a wave in a medium (air , water, light) divided by frequency , equals wavelength . so wavelength = v/f or = 23m/s ÷13hz

Answer:

In a position-time graph, the velocity of the moving object is represented by the slope, or steepness, of the graph line. If the graph line is horizontal, like the line after time = 5 seconds in Graph 2 in the Figure below, then the slope is zero and so is the velocity. The position of the object is not changing.

Answer: Option A.

Spring B has a larger displacement that spring A.

Explanation:

Spring B has a larger displacement that spring A .

By using Hooke's law.

F=-Kx

Where F is force, K is spring constant and x is displacement.

For spring a

Weight / force is 2 kg

Spring constant (K) is 5/nm

Therefore,

F=-Kx

2=-5x

X=2/-5

X= -0.4m

For spring B.

Weight is 10Kg

Spring constant is 9N/m

F=-Kx

10=-9x

X=-10/9

=-1.1m

Therefore Spring B have larger displacement than spring A.

In Hooke's law, negative sign that is present on the spring's force indicate that the force exerted by the spring opposes the spring's displacement.

cause metals on the left and in the center of the periodic table form ionic bonds with nonmetals on the right of the periodic table.

Answer:

The three ways thermal energy is transferred are;

1) Conduction

2) Convection

3) Radiation

Explanation:

1) The conduction of the heat from the open flame to the marshmallow is through the direct contact of the flame with the marshmallow, such that the flame the region of the combustion reaction, that produces light and heat touches the marshmallow

2) The convection process is the transfer of heat from the rising heated combustion products, as well as the heated air that rises from the flame

3) The radiation heat transfer is the transfer of the heat from the fire to the marshmallows directly by the heat the moves in the form of electromagnetic waves at temperatures above 1000 K, without the need for a medium, such that the marshmallow can be heated by the heat coming from side of the flame.
