Hi there!

1)

Since the charge placed in the middle is positive, we know that the particle is being repelled.

The particle experiences a greater repelling force by the 9μC charge. We can use the equation for electric force:
[tex]F_E = \frac{kq_1q_2}{r^2}[/tex]

k = Coulomb's Constant

q₁, q₂: Charges (C)
r = distance between charges (m)

This is a VECTOR quantity, so we must subtract the forces since they point in opposite directions.

Force from 9μC particle:
[tex]F_E = \frac{k(.000005)(.000009)}{2^2} = .101\\\\[/tex]

Force from 4μC particle:
[tex]F_E = \frac{k(0.000005)(0.000004)}{2^2} = 0.0450[/tex]

Subtract:
[tex].101 - 0.0450 = \boxed{0.561 N}[/tex]

2)

We can find a position by setting the two equations equal to one another. (Both repelling forces must be EQUAL for the force = 0 N)

Let the distance between the 9μC and 5μC charge equal 'x', and the distance between the 4μC and 5μC charge equal '4 - x'.

[tex]\frac{k(0.000009)(0.000005)}{x^2} = \frac{k(0.000004)(0.000005)}{(4 - x)^2}[/tex]

Cancel out 'k' and the 5μC value.

[tex]\frac{0.000009}{x^2} = \frac{0.000004}{(4 - x)^2}[/tex]

Solve for 'x' using a graphing utility.

[tex]\boxed{x = 2.4 m}[/tex]

Based on the calculated Young’s modulus of the material, the material the cylinder could most likely be made of is butyl rubber which has a Young’s modulus of 0.001 to 0.002 GPa.

Young's modulus, Y is a measure of a solid's ability to resist deformation in its length under stress or strain.

Mathematically,

where:

Y = Fl/Ae

where;

π = 3.14

r = 2 cm = 0.02

Area of the cylinder = 3.14 × 0.02^2 = 0.00125 m^2

When a mass 5 kg was placed on the cylinder:

F = 5 × 10 = 50 N

l = 10 cm = 0.1 m

e = 10 - 7.73 = 0.39 cm = 0.0039 m

A = 0.00125 m^2

Using Y = Fl/Ae

Y = (50 × 0.1)/(0.00125 × 0.0039)

Y = 1025641.026 N/m^2

1 N/m^2 = 1 × 10^-9 GPa

Y = 0.001025 Gpa

When a mass 50 kg was placed on the cylinder:

F = 50 × 10 = 500 N

l = 10 cm = 0.1 m

e = 10 - 7.73 = 2.27 cm = 0.0227 m

A = 0.00125 m^2

Using Y = Fl/Ae

Y = (500 × 0.1)/(0.00125 × 0.0227)

Y = 1762114.537 N/m^2

1 N/m^2 = 1 × 10^-9 GPa

Y = 0.00176 Gpa

The Young’s modulus of the material is between 0.001025 Gpa and 0.00176 Gpa.

Therefore, the material the cylinder could most likely be made of is butyl rubber which has a Young’s modulus of 0.001 to 0.002 GPa.

The material that the cylinder is made from is Butyl Rubber.

Young's modulus, or the modulus of elasticity in tension or compression, is a mechanical property that measures the tensile or compressive strength of a solid material when a force is applied to it.

[tex]E = \frac{stress}{strain} \\\\E = \frac{F/A}{e/l} \\\\E = \frac{Fl}{Ae} \\\\[/tex]

Where;

When 5 kg mass is applied, the extension = 10 cm - 9.61 cm = 0.39 cm = 0.0039 m.

[tex]E = \frac{(5\times 9.8) \times 0.1}{0.00126 \times 0.0039} \\\\E = 9.97 \times 10^5 \ N/m^2\\\\E = 0.000997 \times 10^9 \ N/m^2\\\\E = 0.000997 \ GPa\\\\E \approx 0.001 \ GPa[/tex]

When the mass is 50 kg,

extension = 10 cm - 7.73 cm = 2.27 cm = 0.0227 m

[tex]E = \frac{(50\times 9.8) \times 0.1}{0.00126 \times 0.0227} \\\\E = 1.7 \times 10^6 \ N/m^2\\\\E = 0.0017 \times 10^9 \ N/m^2\\\\E = 0.0017 \ GPa\\\\E \approx 0.002 \ GPa[/tex]

The Young's modulus is between 0.001 GPa  to 0.002 GPa

Thus, the material that the cylinder is made from is Butyl Rubber.

Answer:

k = 100 N/m

Explanation:

The elastic potential energy of a spring is equal to (1/2)kx^2, where k is the spring constant and x is the distance compressed. If the elastic PE is equal to 2J, we can solve for k. Make sure to convert units from cm to m:

(1/2)kx^2 = 2J

kx^2 = 1

k = 1/x^2

k = 1/(0.1)^2

k = 100 N/m

The density of carbon tetrachloride is 1.59 g/cm^3.

Given the following data:

Mass of flask = 345.8 gVolume of carbon tetrachloride = 225 mLMass of flask and carbon = 703.55 g

To find the density of carbon tetrachloride;

First of all, we would determine the mass of carbon tetrachloride;

Mass of flask and carbon = mass of flask + mass of carbon tetrachloride

703.55 = 345.8 + mass of carbon tetrachloride

Mass of carbon tetrachloride = 703.55 - 345.8

Mass of carbon tetrachloride = 357.75 g

Next, we would solve for the density of carbon tetrachloride by using the formula;

Substituting the values into the formula, we have;

Density = 1.59 g/cm^3

Therefore, the density of carbon tetrachloride is 1.59 g/cm^3.

Explanation:

Answer:

The astronaut will get a velocity 0.064ms−1 opposite to the direction of the object.

If a 75 kg astronaut floating in space throws a 5 kg rock at 5 m/sec, then the astronaut would move backward with a speed of 0.33 meters/second.

It can be defined as the product of the mass and the speed of the particle, it represents the combined effect of mass and the speed of any particle, and the momentum of any particle is expressed in Kg m/s unit.

P = mv

As given in the problem if a 5 kg astronaut floating in space throws a 5 kg rock at 5 m/sec,

By using the conservation of the momentum,

Assuming the initial momentum of the astronaut and ball would have been zero, the total final momentum of the system would be zero as well,

75*v +5*5 = 0

v = 25/75

v = -0.33 m/s

Thus, the astronaut would move backward with a speed of 0.33 meters/second.

Explain why scientists replace an old scientific model with a new model.

Include an example from Physics in your answer.

A scientific model is created to understand the concepts and explain the reason behind unexplained observations.

But the scientific models cannot explain all the unexplained observations.

When another scientific model which could explain some more observations than the previous model.

This new model replaces the old one.

 One such example in physics is geocentric and heliocentric models.

The geocentric model was based on the principle that all celestial bodies revolve around the earth as its center.

But this model failed to explain some planets move backward instead of forward.

The heliocentric model was based on the principle that all planets revolve around the sun as its center including earth.

 This model was able to resolve the backward and forward motion dilemma.

That is why heliocentric replaced the geocentric model.

The model was used by scientists to predict the results of their investigations. The data frequently did not support their forecasts. This required a modification to the model.

The contemporary atomic model emerged as a result of numerous scientists building on one another's research.

Creating a physical, mental, or mathematical model of a genuine occurrence that is challenging to see firsthand is known as scientific modeling.

In a range of scientific disciplines, from chemistry and science to ecology and also the Earth sciences, scientific models are employed to explain and forecast the behavior of real things or systems.

Though modeling is an essential part of contemporary science, scientific models are, at best, approximations rather than perfect representations of the systems and things they represent. As a result, scientists are always trying to enhance and improve models.

Scientific modeling has a variety of goals. Some models, which are frequently developed from experimental data, are being used mainly to visualize an object or system, such the three-dimensional dbl model of DNA.

Answer:

If the mass of one body is doubled, force is also doubled.

Taking into account the Universal Law of Gravitation, if the masses of one body is doubled, the gravitational force between two bodies is also doubled.

The Universal Law of Gravitation establishes that bodies, by the simple fact of having mass, experience a force of attraction towards other bodies with mass, called gravitational force.

The Universal Law of Gravitation states that the gravitational force between two bodies is directly proportional to the product of their masses and inversely proportional to the square of the distance that separates them.

Mathematically it is expressed as follows:

[tex]F=G\frac{Mm}{d^{2} }[/tex]

where:

By definition of gravitational force, the greater or lesser the value of any of the masses causes the force to be greater or lesser respectively.

Finally, if the masses of one body is doubled, the gravitational force between two bodies is also doubled.
