Use this formula m=W/g, What is the mass of an object if its weight on earth is 1150N?

Answers

Answer 1

Using this formula m=W/g, the mass of an object if its weight on earth is 1150N is 117.347 kg

Let mass of an object be m, weight be W and acceleration due to gravity is g.

From the formula m=W/g

mass m =?

weight w = 1150N

g=9.8 m/[tex]s^{2}[/tex]

So,  the mass of an object if its weight on earth is 1150N will be calculated as:

m=1150/9.8

m=117.347 kg

Hence using the formula m=W/g, the mass of an object if its weight on earth is 1150N will be 117.347 kg.

This is in acceptance with Newton's laws of motion as well and thus calculated according to given formula.

According to the giant impact hypothesis about the formation of the moon. Why did the earth not break apart into many pieces when the giant impact happened?

Answers

The earth could not be broken apart by the impactor since it was formed of such light material (mostly gas and liquid).

What are the basic features of the theory of the enormous impact ?

According to the Giant Impact Hypothesis, which is the most widely accepted theory for how the moon formed, the Earth and a Mars-sized object called Theia collided with each other as they were forming as protoplanets. The moon was created from a large amount of debris. According to this theory, the Moon was created after the Earth collided with a smaller planet that was around Mars' size. The Moon was created when the impact's leftover debris gathered in an orbit around Earth.

The larger body may have caught the iron core of the striking object.

The key to this theory is understanding how consciousness works and harnessing its power for good. By doing so, we can help to manifest positive changes in our world collectively.

Answers

The mass of nitrogen is calculated as 1.092 grams

Calculation

According to Dalton's Law of partial pressure:

Pn2 = Ptotal Xn2

Were,

Pn2is the partial pressure of nitrogen

Ptotal is the Total pressure

Xn2is the mole fraction of nitrogen

Given:

Total pressure = 1.0 atm

Mole fraction of nitrogen = 0.78

Partial pressure of nitrogen:

Pn2= 1.0 x 0.78 atm

Partial pressure of nitrogen = 0.78 atm

According to Henry's law:

Solubility = Henry's constant (k)×Partial pressure

k = 6.26×10⁻⁴ mol/L-atm

Thus,

Solubility of nitrogen = 6.26×10⁻⁴ mol/L-atm×0.78 atm = 4.8828×10⁻⁴ mol/L

Given: Volume = 80.0 L

So, Moles of nitrogen gas dissolved:

Moles = Solubility (Concentration dissolved) ×Volume

Moles = 4.8828×10⁻⁴ mol/L×80.0 L = 0.0390 moles

Also,

moles = mass (m) / molar mass (M)

What is the acceleration of a 10 kg mass pushed 5 n forceushed by a 5n(kg-m/s2) (use gresa method)

Answers

The final acceleration of the object is 2 m/[tex]s^{2}[/tex].

In this problem,

Applied force(F) = 10 N

The object’s mass (m) is 5 kg.

Having said that,

An object’s force is equal to the product of its mass and the acceleration it experiences as a result of the applied force.

i.e., Mass + Acceleration = Force (a)

F= m×a

Therefore,

A= F÷m

A= (10÷5) m/sec²

A= 2 m/sec²

Consequently, the object’s acceleration,

A=2 m/sec²

Concept of force and acceleration:

This states that the rate of velocity change of an object is directly proportional to the applied force and moves in the direction of the applied force.

It can be expressed mathematically as force (N) = mass (kg) x acceleration (m/s2). Therefore, an object with constant mass will accelerate in direct proportion to the applied force.

In a first order decomposition, the constant is 0.00586 sec-1. what percentage of the compound is left after 3.32 minutes?

Answers

The correct answer for percentage of the compound is left after 3.32 minutes is 55 % .

We use the formula A(t) = A0e-kt for decomposition, where A0 is the initial amount of decomposed substance at t = 0, k is the decay constant, t is the time elapsed, and A(t) is the amount after time t.

The percentage of decomposed compound left after a time t is, [A(t)], divided the the initial amount, [A0], time 100, or A/A0*100:

A = A0e-kt

A/A0 = e^- 0.00586t, [k = 0.00299, divide both sides by A0]

A/Ao = e^(-0.00299*199), [t = 3.32 min*(60 sec/ 1 min) =199 sec]

A/A0 = . 0.551= 55%, (* 100, rounded)

The Arrhenius equation is k = Ae(-Ea/kT), where A is the frequency or pre-exponential factor and e(-Ea/RT) is the fraction of collisions at temperature T that have enough energy to overcome the activation barrier (i.e., have energy greater than or equal to the activation energy Ea).

How much compression would happen if you started with 200cm of air inside a syringe

Answers

Air starts exerting more and more pressure on the walls of the syringe

What will happen to air particles when the are being compressed in a syringe?

Although the space has grown, the individual atoms and molecules can now go farther before running into a nearby atom or molecule because they can now bounce off the walls of the syringe instead of directly bouncing into one other.

Additionally, as the syringe is compressed, you are essentially cramming the same molecules into less space, which causes them to traverse shorter distances and collide more frequently.

This has to do with pressure because when molecules strike the syringe's walls, they bounce off, creating a force and response force that keeps the syringe's walls stiff against the environment it's in or the outside atmosphere. Atoms and molecules essentially bounce off the walls inside the syringe just as much as molecules outside the syringe do when the pressure inside and outside is equal. When the volume of the syringe is increased, the air molecules fill it up, which results in fewer impacts with the inner wall and less force holding the interior rigid to the exterior. Conversely, when the volume is decreased, the impacts happen more frequently because the molecules have nowhere else to go and no more space to travel before encountering another molecule or a wall, so the increase in the frequency of the impacts leads to an increase in the force holding the interior rigid to the exterior.

During the first 0.5 s, u = 0 and v = 1 m / s.

d = ( 0 + 1 ) * 0.5 / 2

d = 0.25 m

During the next 0.5 s, u and v are equal meaning constant velocity ( V = 1 m / s ).

d = 1 * 0.5

d = 0.5 m

During the next 1 s, u = 1 m / s and v = 1.5 m / s.

d = ( 1 + 1.5 ) * 1 / 2

d = 1.25 m

During the next 2.5 s, u and v are equal meaning constant velocity ( V = 1.5 m / s ).

d = 1.5 * 2.5

In physics, vertical launch upward may be characterized as the motion that is illustrated by an object that has been set afloat vertically upwards in which the height and the consequences of the earth's gravitational force set in motion of an object are taken into consideration.

According to the question,

The formula for the vertical launch upward may be as follows:

y max = v₀²/(2*g).

where v₀ = initial velocity

           g = gravity max = maximum height.

We know that,

g = 32.17 ft/s²

On applying the formula of maximum speed and clearing the initial velocity we get:

y max = v₀²/(2*g)

v₀ = √(y max * (2*g)

v₀ = √( 18.1 ft * (2 * 32.17 ft/s²)

v₀ = √( 18.1 ft * 64.34 ft/s²)

What is meant by electric force?

The electric force attracts the nucleus and electrons to one another. The emptiness that a positive or negative charge leaves behind is known as an electric field because a field is produced there.

Electrical forces can be categorized into two groups: those that attract and those that repel. While opposite charges attract one another, similar charges repel one another.

Electrical forces are produced when two charges come into contact with one another. The electric force exerted on a single charge when there are three or more charges present is just the culmination of the results of each charge's interactions with the other charges.

Are the stack temperature and oxygen reasonable for these operating conditions? if not, what oxygen and stack temperature would you recommend if not? what is the efficiency with your chosen values?

Answers

Stack temperatures typically range from 350 to 450 degrees Fahrenheit. A 2.5% efficiency loss occurs for every 100 degrees over that temperature. The majority of buildings schedule annual boiler cleanings at regular intervals, but if you see those figures rise, it's time for a cleaning.

Excess air is required to completely burn the fuel since the air and fuel cannot combine exactly in a burner. Additionally, any leaks in the heater will draw air into the firebox that doesn't pass through the burners since the furnace or boiler firebox operates at a little negative gauge pressure. Fuels that are gaseous, like natural gas, burn more readily than fuels that are liquid or solid. Depending on the fuel type, different surplus air requirements will apply.
