Calculate the pressure exerted by the two straps of a handbag that has a force of 15N, and covers an area of 0.5cm2 (each)

Answers

Answer 1

Answer:

Pressure = 3000N/m²

Explanation:

Given the following data;

Force = 15N

Area = 0.5cm² to meters = 0.5/100 = 0.005m²

To find the pressure;

Pressure = Force/area

Substituting into the equation, we have:

Pressure = 15/0.005

Pressure = 3000N/m²

How can you prove that air contains carbon dioxide?​

Answers

Answer:

Limewater can be used to detect carbon dioxide. If carbon dioxide is bubbled through limewater then it turns from clear to cloudy/milky in colour. This is why limewater used in a simple respirometer can show that more carbon dioxide is present in exhaled air compared to inhaled air.

Explanation:

Answer:

Explanation:

Carbon dioxide (CO 2) is colorless and odorless, so you can't detect it through direct observation. You'll need to collect an air sample (or a CO 2 sample), then run one of several simple tests to identify the presence of the gas

A vector quantity is : A deer running 15 meters per second due west

Answers

Answer:

True.

Explanation:

Velocity can be defined as the rate of change in displacement (distance) with time. Velocity is a vector quantity and as such it has both magnitude and direction.

Mathematically, velocity is given by the equation;

[tex]Velocity = \frac{distance}{time}[/tex]

Simply stated, a vector quantity has both magnitude and direction.

Explain how sharpening a knife changes is MA (mechanical advantage).

Answers

Answer:

Sharpening a knife reduces it's height as a wedge thus giving it more efficiency.

Explanation:

Mechanical advantage refers to the degree or quantity to which a force is increased or amplified by using a tool or a machine.

Mechanical Advantage can be calculated as follows:

Lenght of Incline (LI) / Height of Incline (HI)

Assume I have constructed a hedge with an inclination that run 10 meters from point x to point y (which is the back of a truck. Point y to the floor is 5 meters.

If   LI = 10m and

HI= 5m

The mechanical advantage is given as 10/5 = 2

The angle of incline is also called the effort distance. From our calculations above, by sacrificing horizontal movement, I reduced the amount of effort it would have cost to lift up that object from ground up -  a distance of 5 meters.

Think of a knife as a form of a similar wedge.

The more a knife is sharpening of a knife further reduces its angle of elevation. Thats why it becomes more efficient to use, hence our mechanical advantage.

How would the model change as the atom forms bonds? The third shell would have eight electrons after the atom gains seven electrons to fill the outermost shell. The third shell would be empty so that the eight electrons in the second level would be outermost after the atom loses one electron. The first and third shells would be empty so that the atom would have eight electrons in its remaining shell after the atom loses three electrons. The first shell would have two electrons and the second shell would have six electrons after the atom loses three electrons.

Answers

Answer:

The third shell would be empty, so the eight electrons on the second level would be the outermost after the atom lost one electron

Explanation:

When an atom is bonded with other atoms, a more stable configuration must be reached, which is why the energy of the molecule is less than the energy of the individual atoms, for this to happen in general, electrons are shared or lost and gained in each atom, depending on the electronegative of the same.

If we analyze an atom within the molecule, its last shell is full, in the case of atoms with few electrons in this shell, they are lost and in the case of many electors in this shell, it gains electrons to have eight (8) in total.

When reviewing the different answers, the correct one is:

What's the Difference Between Weather and Climate?what is the difference between weather and climate

Answers

Answer:

weather and climate are different.

weather is when conditions in the atmosphere remain for a short time period.

example: Today's weather is rainy but tomorrow's weather will be sunny.

climate is when the conditions in the atmosphere are daily for a extended period of time at a certain location.

example: The climate in South Korea during winter is cold but sunny.

Difference between Weather and Climate

Weather is the state of the atmosphere over an area at any point of time while climate is the sum total of weather conditions and variations over a large area for a long period of time.Weather conditions change frequently whereas climate does not change so frequently, it remains same year after year.Weather data are recorded at a specific time while climate is recorded for a longer period of time.Example of weather: dry weather, windy weather, etc. Example of climate: tropical monsoon climate, equatorial climate, etc.

Look carefully at the diagram below, which shows two cells connected in series. What will the reading on the ammeter be?
Enter your answer as a number
Submit
1.5v
1.5v

Answers

Answer:

The reading on the ammeter is 0 ampere

Explanation:

When two or more voltage sources are arranged in series as shown in the diagram, the resultant voltage is given by the sum of the voltages by taking into consideration the direction of the polarities of the voltage sources which can be either series aiding voltage source configuration or series opposing voltage source  configuration

In the series aiding voltage source configuration, the positive terminal of one voltage source is connected to the negative terminal of the next voltage source such that the current flows in the same direction in both sources of the voltage in the circuit and the resultant voltage source is given by adding the individual voltage sources together

However, in the series opposing voltage source configuration, the positive terminal of one voltage source is connected to the positive terminal of the next voltage source such that the current flows in opposite direction in both voltage sources and the voltage across the entire voltage sources is given by finding the sum of the differences of the opposing voltage sources

The arrangement of the voltage sources in the question is one of a series opposing voltage configuration and the voltage across both voltage sources is given by subtracting one (usually the smaller voltage source) from the other as follows;

[tex]V_{(series \ opposing)}[/tex] = V₁ - V₂

Where;

V₁ = The voltage of one (usually the larger) of the voltage source = 1.5 V

V₂ = The voltage of the other voltage source = 1.5 V

Therefore;

[tex]V_{(series \ opposing)}[/tex] = 1.5 V - 1.5 V = 0 V

The reading on the ammeter = The current in the circuit, 'I', which is given as follows;

V = I·R

∴ I = V/R = 0/R = 0

I = 0 A (ampere)

The reading on the ammeter = I = 0 A (Current cannot flow without the presence of a voltage).

The law of conservation of momentum states that, if left alone, what happens to the total momentum of two interacting objects that make up a system? it increases over time it remains the same it eventually becomes zero changes based on how they collide

Answers

Answer:

it remains the same

Explanation:

Momentum can be defined as the multiplication (product) of the mass possessed by an object and its velocity. Momentum is considered to be a vector quantity because it has both magnitude and direction.

Mathematically, momentum is given by the formula;

Momentum = mass * velocity

The law of conservation of momentum states that the total linear momentum of any closed system would always remain constant with respect to time.

Hence, the law of conservation of momentum states that, if left alone, the total momentum of two interacting objects that make up a system remains the same.

This ultimately implies that, if two interacting objects exert forces only on each other, their total momentum will remain the same i.e it is conserved.

Answer:

it remaines the same :)

A. 15m/s^2

B. 5m/s^2

C. 20m/s^2

D. 3m/s^2

Answers

Answer:3 m/s

Explanation:

The resulting acceleration to move the 5Kg box is equal to 3m/s². Therefore, option (D) s correct.

What is acceleration?

Acceleration can be defined as the rate of change in the velocity of an object with respect to time. The acceleration of an object is a vector parameter with both magnitude and direction. Acceleration is also defined as the first derivative of the velocity w.r.t. time and the second derivative of position w.r.t. time and

According to Newton's 2nd law of motion, the force is equal to the product of the mass (m) and acceleration.

F = ma

And,   a = F/m

Therefore, the acceleration (a) inversely proportional to the mass (m).

Given, the force used to move the box, F = 15 N

The mass of the given Box, m = 5 Kg

The resulting acceleration, a  = 15/5 = 3 m/s²

Therefore, the acceleration of the box is equal to  3 m/s² when it is pushed with a force of 15 N.

An object accelerates at 50 m/s/s with a force of 100 N. What is its mass?

Answers

Answer:

Explanation:

A change in an object’s motion—such as Xander speeding up on his scooter—is called acceleration. Acceleration occurs whenever an object is acted upon by an unbalanced force. The greater the net force acting on the object, the greater its acceleration will be, but the mass of the object also affects its acceleration. The smaller its mass is, the greater its acceleration for a given amount of force. Newton’s second law of motion summarizes these relationships. According to this law, the acceleration of an object equals the net force acting on it divided by its mass. This can be represented by the equation:

Acceleration=Netforce-Mass or a=F/m

Una fuente luminosa de 75 W consume 75W de potencia electrica. Suponga que toda la energía se transforma en luz emitida de 600 nm de longitud de onda. a) Calcule la frecuencia de luz emitida b) ¿Cuántos fotones por segundo emite la fuente? C) ¿Son iguales las respuestas de de los incisos a) y b)?

Answers

Answer:

a) La frecuencia de la luz emitida es 5,0 × 10¹⁴ Hz

b) El número de fotones por segundo que emite la fuente es 2.26380924 × 10²⁰ fotones

c) Las respuestas del inciso a) yb) son diferentes

Explanation:

Los parámetros dados son;

La potencia de la fuente de luz, P = 75 W

La energía consumida cada segundo por la fuente de luz, E = 75 J

La longitud de onda de la luz emitida, λ = 600 nm

a) La relación entre la energía y la frecuencia de la luz se da a continuación;

υ = c/λ

E = n·h·υ

[tex]E = \dfrac{h \times c}{\lambda}[/tex]

Dónde;

E = La energía consumida por segundo = 75 J

h = constante de Planck ≈ 6.626 × 10⁻³⁴ J · s

υ = La frecuencia de la luz

λ = La longitud de onda de la luz = 600 nm

c = La velocidad de la luz, c = 3.0 × 10⁸ m / s

Por lo tanto, tenemos;

υ = c / λ = 3,0 × 10⁸ m / s / (600 nm) = 5,0 × 10¹⁴ Hz

∴ La frecuencia de la luz emitida, υ = 5.0 × 10¹⁴ Hz

b) El número de fotones por segundo que emite la fuente, 'n', se da como sigue;

n = E / (h · υ) = 75 J / (6.626 × 10⁻³⁴ J · s × 5.0 × 10¹⁴ Hz) = 2.26380924 × 10²⁰

El número de fotones por segundo que emite la fuente = n = 2.26380924 × 10²⁰ fotones

c) Las respuestas del inciso a) yb) son diferentes

5.0 × 10¹⁴ Hz ≠ 2.26380924 × 10²⁰ fotones.

3.00 m3 of a fixed mass of a gas at 150 kPa. Calculate the pressure if the volume is reduced to 1.20 m3 at a constant temperature.

Answers

Answer:

P₂ = 375 kPa.

Explanation:

Given that,

Initial volume, V₁ = 3 m³

Initial pressure, P₁ = 150 kPa

Final volume, V₂ = 1.2 m³

We need to find the final pressure.

At constant temperature,

[tex]P\propto \dfrac{1}{V}\\\\P_1V_1=P_2V_2\\\\P_2=\dfrac{P_1V_1}{V_2}\\\\P_2=\dfrac{150\ kPa\times 3\ m^3}{1.2\ m^3}\\\\P_2=375\ kPa[/tex]

So, the new pressure is 375 kPa.

what is the momentum of a bicycle with a mass of 18 kg traveling at 20 m/s?

Answers

Answer:360 kg m/s

Explanation:Momentum refers to an object's quantity of motion.

Formula for Momentum: p=mv

p = refers to the momentum

m = refers to the object's mass (this is represented by the unit kg or kilogram)

v = this refers to the object's velocity (this is represented by the unit m/s or meter per second)

So, given that the bike has a mass of 18 kg and is traveling at 20 m/s, then you can already get the momentum by multiplying both of these values.

p = the bike's momentum (what is being asked here)

m = 18 kg

v = 20 m/s

Thus, p = 18kg × 20 m/s = 360 kg m/s

The bike's momentum is 360 kg m/s.
