Answer:

never....(D)

Explanation:

hope this helps, the person above me is also correct

Covalent compounds never conduct electricity as we know that these compounds are formed by the sharing of electrons where free electrons are unavailable for the flow of the electric current.

Therefore the correct answer is option D.

Covalent bonds are formed between two atoms, whether they are similar or different when they share an extra electron.

The transport of electrons produces the ionic bond.

Intermolecular compounds are known to never carry electricity because they are created by shared electrons, which prevents free electrons from being available for the transmission of an electric current.

Option D is the right response as a result.

This question would be a piece o' cake, except that we don't know your observations, your data, or your conclusions.

We also don't know the first method, the second method, the accuracy of either method, the displacement method, or what you found out from this investigation.

Otherwise, like I said, this is really no problem.

Answer:

F = 9.81 [N]

Explanation:

To solve this problem we must use Newton's third le which tells us that the sum of forces on a body that remains static must be equal to one resulting from these forces in the opposite direction.

Let's perform a summation of forces on the vertical axis-y to determine the normal force N.

∑F = 0 (axis-y)

[tex]N - m*g = 0[/tex]

where:

m = mass = 4 [kg]

g = gravity acceleration = 9.81 [m/s²]

[tex]N - (4*9.81)=0\\N = 39.24 [N][/tex]

Now we know that the frictional force can be calculated using the following equation.

f = μ*N

where:

f = friction force [N]

μ = friction coefficient = 0.25

N = normal force = 39.24 [N]

Now replacing:

[tex]f = 0.25*39.24\\f = 9.81[N][/tex]

Then we perform a sum of forces on the X-axis equal to zero. This sum of forces allows us to determine the minimum force to be able to move the object in a horizontal direction.

∑F = 0 (axis-x)

[tex]F-f=0\\F-9.81=0\\F= 9.81[N][/tex]

If the coefficient was smaller, a smaller force (F) would be needed to start the movement, this can be easily seen by replacing the value of 0.25, by smaller values, such as 0.1 or 0.05.

If the coefficient were larger, a larger force would be needed.

Answer:

1.78m/s

Explanation:

Given parameters:

Velocity of the arrow = 22.8m/s

Height of the wall  = 15.5m

Unknown:

Time taken for the arrow to reach the ground  = ?

Solution:

To solve this problem we employ the appropriate motion equation:

     H  = ut + [tex]\frac{1}{2}[/tex] g t²

 H  is the height

  u is the initial velocity = 0

   g is the acceleration due to gravity  = 9.8m/s²

  t is the unknown time

  15.5 = [tex]\frac{1}{2}[/tex] x 9.8 x t²

  15.5 = 4.9t²

     t² = 3.16

      t = 1.78m/s

Answer:

Explanation:

The solution along with the diagram can be found in the attachment. Feel free to raise doubts.

Centripetal force is defined as the force that allows the object to follow a curvature path.

The velocity will be 19.80 m/s.

Given:

Normal Force = 1.2 x weight

Normal Force = 1.2 Mg

Mass = Mass of car + occupants

Centripetal Acceleration = [tex]\text a_c[/tex]

Now, applying the equilibrium equation:

[tex]\begin{aligned} \sum \text F&= \text m \times \text a_c\\\\\text F_n - \text{mg} &= m \times \text a_c\\\\1.2 \text{Mg} - \text{Mg} &= m \times \text a_c\\\\\text a_c &=0.2 \;\text g\\\end[/tex]

Now, substituting the value in the formula:

[tex]\begin {aligned} \text a_c &=\dfrac{\text v^2}{\text r}\\\\0.2 \text g &= \dfrac {\text v ^2}{\text r}\\\\\text v &= \sqrt{0.2 \times 9.8 \times 200}\\\\\text v &= 19.80 \;\text {m/s}\end[/tex]

Thus, the velocity will be 19.80 m/s.

Answer: 0.064 m/s²

Explanation:

Initial velocity = 22m/s

Final velocity = 44m/s

Time taken = 345 seconds

Acceleration = (Final velocity - Initial velocity) / Time taken

= (44 - 22) / 345

= 22/345

= 0.0637681

= 0.064 m/s²

Therefore, the acceleration is 0.064 m/s².

Answer: The correct order of energy transformation is from CHEMICAL ENERGY to ELECTRICAL ENERGY to LIGHT ENERGY

Explanation:

Energy which is simply defined as the ability to perform work is made up of different forms, these include:

- Mechanical energy: Associated with machines at work.

- LIGHT ENERGY: produced by light bulbs

- ELECTRICAL ENERGY: taking in by television set and other electrical appliances.

- CHEMICAL ENERGY: stores in food and other fuels

- Sound energy: Produced by vibrating objects example piano, drums.

According to the law of conservation of energy, energy can neither be created nor destroyed in a closed system, but can be transformed from one form to another, thereby keeping the energy in the closed system constant. From the question, the circuit is an example of a closed system and the order of energy transformation taking place is from the battery (CHEMICAL ENERGY) to ELECTRICAL ENERGY(power source) to LIGHT ENERGY(bulb). I hope this helps, thanks.

Answer:

Exposing it to a very strong magnetic field

Explanation:

Aluminium is a non magnetic metal thus it is not magnetic under normal conditions. This is because it interacts with other magnets. The only condition that magnetism can be induced in aluminium is exposing it to a very strong magnetic field.

Answer:

1620000J

Explanation:

Given parameters:

Power = 180000W

Time  = 9s

Unknown:

Work done by the engine = ?

Solution:

Power is the rate at which work is being done.

 Now,

        Power  = [tex]\frac{Work done }{time}[/tex]  

 Work done  = Power x time taken

 Work done  = 180000 x 9  = 1620000J

Explanation:

Sound waves travel over 17 times faster through steel than through air.

Answer:

Steel

Explanation:

This is because solid objects molecules are more packed together, therefore it travels faster, in which time oxygen by 17 times faster
