Answer:

a) F = 40 N

b) It is acting towards left

c) a = 10 m/s²

Explanation:

As the block of mass and its forces are not shown, the question is incomplete.

First we attach the diagram of the attached question (See below)

We can see in the diagram that there are total of 5 forces acting on that block. Consider the forces acting towards right to be positive and the forces acting towards left be negative (or vice versa, the answer would be same). Let them be:

F₁ = 10 N

F₂ = 17 N

F₃ = 21 N

F₄ = -35 N

F₅ = -53 N

To find resultant force, we'll add all of the 5 forces.

Resultant Force = F₁ + F₂ + F₃ + F₄ + F₅

Resultant Force = 10 + 17 +21 - 35 - 53

Resultant Force = -40 N

As the resultant force has a negative sign, and previously we stated that the forces acting towards left are negative, so the Resultant Force is acting in the left direction.

We know that

F = (m)(a)

Where F is the resultant force we found. Resultant Force was -40N , where negative sign only represents the direction. We'll consider only the magnitude which is 40N, where m is the mass of the block which is 4 kg. Substitute in the equation.

40 = (4)(a)

a = (40)(4)

a = 10 m/s² (in left direction)

Explanation:

I took this test.

The given photon has a wavelength of approximately 45 nm. A photon is an elementary particle that carries energy and exhibits wave-particle duality, being the basic unit of electromagnetic radiation and light.

The wavelength of the photon is determined to be 45 nm. A photon is an elementary particle that acts as a quantum of the electromagnetic force and the fundamental unit of light and other types of electromagnetic radiation. It has no charge and possesses both particle-like and wave-like characteristics.

The energy change of an electron within an excited hydrogen atom leads to the emission of a photon with a frequency of 6.7 × 10^15 Hz. Using the equation E = hf, where E represents energy, h is Planck's constant, and f denotes frequency, we can calculate the energy of the photon. Substituting the given values, we have E = 6.7 × 10^15 × 6.626 × 10^-34 = 4.44 × 10^-18 J.

To determine the wavelength of the photon, we can utilize the equation c = fλ, where c represents the speed of light and λ denotes wavelength. Rearranging the equation to solve for λ, we have λ = c / f. Substituting the values of c (the speed of light, approximately 2.998 × 10^8 m/s) and f (the frequency of the photon), we obtain λ = 2.998 × 10^8 / 6.7 × 10^15 = 4.48 × 10^-8 m. Rounding this value to the nearest whole number, we find that the wavelength of the photon is 45 nm.

Therefore, the given photon has a wavelength of approximately 45 nm. A photon is an elementary particle that carries energy and exhibits wave-particle duality, being the basic unit of electromagnetic radiation and light.

Explanation:

To examine and characterize matter, employ its physical qualities. Physical characteristics include things like shape, feel, color, smell, melting temperature, boiling point, density, solubility, polarity, and a host of other things.

Any measurable attribute that characterizes the condition of a physical system through its values is referred to as a physical property. The transitions between a system's brief states can be described by changes in physical characteristics of the system.

Measurements are a common nickname for physical characteristics. The properties are not modal. Physical amount refers to that of an identifiable physical characteristic.

Physical characteristics are often divided in intensive and extensive properties. Whereas an extensive property exhibits an additive relationship, an intensive property is independent by the system's size, scope, or the volume of its constituent parts. These categories are typically only relevant when the sample's smaller subgroups do not interact physically or chemically when combined.

Answer: The change in momentum is +20 kg.m/s

Explanation:

To calculate the final velocity of object, we use the first equation of motion:

\(v=u+at\)

where,

v = final velocity

u = initial velocity = 0 m/s

a = acceleration = \(10m/s^2\)

t = time = 0.5 s

Putting values in above equation, we get:

\(v=0+(10\times 0.5)\\\\v=5m/s\)

Momentum is defined as the product of the mass and velocity of an object. It is given by the equation:

\(p=mv\)

where,

p = momentum

m = mass of object = 2 kg

Let the upward velocity be positive and the downward velocity be negative

When the object is dropped, the velocity is downward

v = -5m/s

Initial momentum = \(2kg\times (-5m/s)=-10kg.m/s\)

When the object is bounced back, the velocity is upward

v = +5m/s

Final momentum = \(2kg\times (+5m/s)=10kg.m/s\)

Change in momentum = Final - Inital

Change in momentum = [10 - (-10)] = +20 kg.m/s

Hence, the change in momentum is +20 kg.m/s

While both universal gravitation and electric force equations involve the inverse square law and a constant, they differ in the nature of the objects involved and the type of force that is generated.

A Venn diagram is a useful tool to compare and contrast two concepts, so let's use it to analyze universal gravitation and electric force equations.
Universal gravitation equation: \(F=G(m1m2/r^2)\)
Electric force equation: \(F=k(q1q2/r^2)\)
In terms of similarities, both equations involve the inverse square law, meaning that the force decreases as the distance between the two objects increases. Additionally, both equations involve a constant, G or k, which determines the strength of the force.
In terms of differences, the universal gravitation equation involves two masses (m1 and m2), while the electric force equation involves two charges (q1 and q2). Gravitation is an attractive force between two masses, while electric force can be attractive or repulsive depending on the charges of the objects.

The procedure and data analysis method that a student used to determine the index of refraction nglass is an experiment where they shine a ray of light from air into the glass.

One possible procedure could involve measuring the angle of incidence and the angle of refraction using a protractor or other measuring tool. The student could vary the angle of incidence and measure the corresponding angle of refraction to obtain a range of data points. To analyze the data, the student could plot the sine of the angle of incidence against the sine of the angle of refraction. The slope of this line would be equal to the reciprocal of the index of refraction of the glass. The student could then use this slope to calculate the index of refraction nglass of the glass.

Another method that could be used to analyze the data is to apply Snell's Law, which states that the ratio of the sines of the angle of incidence and the angle of refraction is equal to the ratio of the indices of refraction of the two media. By measuring the angles of incidence and refraction, the student could plug these values into Snell's Law to calculate the index of refraction nglass of the glass.

Explanation:

The electric field equals the force exerted by the unit positive charge. The electric field at point P is 3.615×10⁶  N/C. Its unit is N/C.

When a charged particle is got influenced by another charged particle when bring near to it, a field is created by an electric charge. This field is called the electric field.

The electric field is obtained by taking the ratio between Force and unit positive charge. Force in a charge is because of attraction and repulsion. The SI unit of force is Newton (N).

The unit positive charge is the test charge used to analyze the other charges present in the field. The SI unit of charge is Coloumb (C). The charge is responsible for the creation of an electric field.

From the givens,

The charge  q₁ = q₂ = 5×10⁻⁸ C,

The distance of charges from point P, r₁ = 0.424 m; r₂ = 0.636 m.

The net electric field E = E₁ + E₂

Electric field E = F / q

 E₁ = kq₁ / r₁²          (k = 9×10⁹ Nm²/C²)

     =  9×10⁹× 5×10⁻⁸ / (0.424)²

  E₁   = 2.503×10³ N/C.

E₂ = kq₂ / r₂²

    = 9×10⁹× 5×10⁻⁸ / (0.636)²

E₂ = 1.112×10³ N/C

E = E₁ + E₂

  =2.503×10³ + 1.112×10³

  = 3.615×10³ N/C

Hence, the net electric field is 3.615×10³ N/C.

Answer:

Explanation:

For an object falling under the influence of gravity, the mass does not affect the acceleration -- that is a constant called "g". As the mass gets larger, it takes a greater force (supplied by the greater weight) to be able to support the same acceleration. g=F/m. The weight (the force) is proportional to mass, so the fraction is the constant g.

UNIT CONVERSION is the process of changing a measurement from one unit to another. To convert pounds (lbs) to Newtons (N), you will use the conversion factor of 1 lb = 4.448 N. This means that one pound is equivalent to 4.448 Newtons.

To perform the conversion, you will multiply the number of pounds by the conversion factor. The formula for this is: Newtons = Pounds x 4.448

For example, let's say you want to convert 50 pounds to Newtons. Using the formula above, you would perform the following calculation:

Newtons = 50 x 4.448 = 224.4

It's important to note that weight is a force, and Newton is the International System of Units (SI) unit of force. So, when you converting weight from pounds to Newton, you are actually converting a force.

It's also worth noting that UNIT CONVERSION can also be done using a conversion calculator. With this calculator, you can input the value in pounds, select Newtons from the drop-down menu, and the calculator will automatically perform the conversion for you.
