Answer: nah

Explanation:

A wet lab experiment for Coulomb's law involves measuring the force between charged objects immersed in a liquid. The experiment is called a "wet" lab because it involves liquid or aqueous solutions.

Coulomb's law is an equation that describes the electrostatic force between two charged particles.

It states that "the force is directly proportional to the product of the charges and inversely proportional to the square of the distance between them."

The equation is given by:

F = k×(q₁ × q₂) / r²

Where

F = the electrostatic force,

k =Coulomb's constant,

q₁ and q₂= the charges of the particles,

r =the distance between the.

In this question,

In the experiment, two conductive objects are charged with opposite charges using a high-voltage power supply, which can be controlled to vary the magnitude of the charges.

The two objects are then immersed in a non-conductive liquid, such as oil or water, and positioned a fixed distance apart.

Using a force sensor or a balance, the force between the two objects is measured as they move toward each other. By measuring the force at different distances, the experiment can verify Coulomb's law, which predicts that the force between two charged objects is proportional to the product of their charges and inversely proportional to the square of their separation distance.

The experiment can be performed with different pairs of charged objects with different magnitudes of charge and separation distances, allowing the relationship between the force and these variables to be investigated. This provides insight into the electrostatic interaction between charged objects in a liquid, which has applications in various fields, including electrochemistry, material science, and biophysics.

Therefore, in a wet lab experiment on Coulomb's law, we have to immerse the apparatus in aqueous solutions.

Answer:

E = 600 J

Explanation:

Given that,

Voltage, V = 10 V

Current, I = 2 A

Time, t = 30 s

We need to find the energy transferred. Energy transferred is calculated as follows :

[tex]E=I^2Rt[/tex]

Ohm's law, V = IR, R = V/I

[tex]E=I^2\times \dfrac{V}{I}\times t\\\\E=IVt\\\\E=2\times 10\times 30\\\\E=600\ J[/tex]

So, 600 J of energy is transferred.

Answer:

1.9976 m

Explanation:

An iron bar whose initial length is 2m has its temperature increased from 20 ° C to 120 ° C. What is the final length of the bar? (consider that the coefficient of expansion of iron) is 1.2 x 10-5 1 / ° C (3 points)

Given that,

Initial length of an iron bar, [tex]L_0=2\ m[/tex]

The temperature increased from 20°C to 120°C

The coefficient of expansion of iron is [tex]1.2\times 10^{-5}\ /^{\circ} C[/tex]

We need to find the final length of the bar.

The linear expansion equation is given by :

[tex]\Delta L=\alpha L\Delta T[/tex]

Where [tex]\Delta L[/tex] is the change in length

[tex]\Delta L=1.2\times 10^{-5}\times 2\times (120-20)\\\\=0.0024\ m[/tex]

Also, [tex]\Delta L = L_o-L[/tex]

L is final length

[tex]0.0024= 2-L\\\\L=2-0.0024\\\\=1.9976\ m[/tex]

So, the final length of the bar is 1.9976 m

Answer:

The car takes 7 seconds to speed up and get out of the way

Explanation:

Constant Acceleration Motion

It's a type of motion in which the velocity of an object changes uniformly over time.

Having a as the constant acceleration, vo the initial speed, vf the final speed, and t the time, the following relation applies:

v_f=v_o+at

Using the above equation we can solve for t:

[tex]\displaystyle t=\frac{v_f-v_o}{a}[/tex]

The car has an initial speed of vo=25 m/s and ends up at vf=60 m/s with an acceleration of a=5 [tex]m/s^2[/tex].

Given all the appropriate data, calculate t:

[tex]\displaystyle t=\frac{60-25}{5}[/tex]

Calculating:

[tex]\displaystyle t=\frac{35}{5}[/tex]

t = 7 seconds

The car takes 7 seconds to speed up and get out of the way

Answer: 5000N

Explanation:

The basic principle of a circular orbit is that Fg = m × ac, so as we have the mass and the centripetal acceleration (also called normal acceleration) we just have to operate. Fg = 1000kg × 5m/s² = 5000N

The gravitational force exerted on the satellite of mass 1000 kg moving in a circular orbit with a centripetal acceleration of 5 m/s² by the planet is 5000 N (option C).  

The gravitational force exerted on the satellite by the planet will be equal to the planet's gravity, which is equal to the centripetal force, so:

[tex] F_{g} = F_{c} = ma_{c} [/tex]

Where:

m: is the mass of the satellite = 1000 kg

[tex]a_{c}[/tex]: is the centripetal acceleration = 5 m/s²

The, the force acting on the satellite is:

[tex] F_{c} = ma_{c} = 1000 kg*5 m/s^{2} = 5000 N [/tex]

Therefore, the gravitational force exerted on the satellite by the planet is 5000 N (option C).

Answer:

There are seven base SI units corresponding to different parameters and are considered independent of each other. Derived units are derived from these 7 base units. Derived units are dependent on the base units and are not independent of each other. For example, let us derive the SI units for force. By Newtons Second Law of Motion, the force is same as the product of mass and acceleration of a body. that is, force = mass x acceleration. Also, acceleration is defined as the rate of change of velocity. And velocity is defined as the rate of change of displacement. Thus, force = mass x acceleration = mass x dv/dt = mass x dt2 Mass has SI units of kg, distance is measured in m and t has the SI unit of second. Thus, Sl unit of force is kg.m/s^2 (also known as Newton).

Given :

A rectangular solid box of aluminum is heated.

To Find :

Which of the following is not true.

A) Its mass remains constant

C) its density increase

B) Its volume increase

D) none of the above​

Solution :

We know, when an object is heated it expands.

Objects expands means that the volume increases but mass remains same by conservation of mass.

Since mass remains constant and volume increases.

So, density will decrease.

Hence, this is the required solution.
