I need some help with this table, i am unsure on how to answer it.

Answer:3 m/s

Explanation:

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

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.

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.

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).

Answer:

X-linked is a trait where a gene is located on the X chromosome. Humans and other mammals have two sex chromosomes, the X and the Y. In an X-linked or sex linked disease, it is usually males that are affected because they have a single copy of the X chromosome that carries the mutation.

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

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

Note: The first three points are the main differences. The last one is the example.

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:

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

Answer: B) Cells come in different shapes and different sizes.

Explanation:

Cell is the basic unit of life. Each cell forms the an integral component of the body of the living organism. The cell structure and function varies from organism to organism. The cells of the plants are comparatively larger than the animal cells. The plant cells are usually rectangular in shape whereas that of animals are usually circular or round in shape. The shape and size of the cells can vary depending upon the function and structure of the organism.

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 :)

Explanation:

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.

Why is it important that your finger be wet if you intend to touch it briefly to a hot clothes iron to test its temperature. If your finger is wet, some of the heat transmitted to your finger will be given to the water which has a high specific heat capacity and also a larger latent heat of vaporization.

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.
