A car traveling on a straight road at 15.0 meters per second accelerates uniformly to a speed of 21.0 meters per second in 12.0
oksano4ka [1.4K]
<h2>Option 3,  216 m is the correct answer.</h2>

Explanation:

We have initial velocity, u = 15 m/s

Time, t = 12 seconds

Final velocity, v = 21 m/s

We have equation of motion v = u + at

Substituting

                     21 = 15 + a x 12

                       a = 0.5 m/s²

Now we have equation of motion v² = u² + 2as

                           21² = 15² + 2 x 0.5 x s

                            s = 216 m

       Displacement = 216 m

Option 3,  216 m is the correct answer.

The SAME amount of current I passes through three different resistors. R2 has twice the cross-sectional area and the same length
Snezhnost [94]

Answer:

resistor R₂ has the lowest current density

Explanation:

The current density is

          j = I / A

now let's analyze each case

a) R₂ has an area 2A₀ and a length L₀ that R₁

b) R₃ has an area Ao and a length 3L₀ what R₁

we can see that all the area is given in relation to the resistance R₁

 

the current density in R₁ is

         j₁ = I / A₀

the current density in R₂

         j₂ = I / 2A₀

         j₂ 2 = ½ I/A₀

the current density in R₃

         j₃ = I / A₀

         j₂ < j₁ = j₃

therefore resistor R₂ has the lowest current density

Which of the following statements is not consistent with the properties of a molecular solid?a. a compound that conducts electri
erica [24]

Answer:

The correct answer to the question is

a. a compound that conducts electricity when molten

Explanation:

A molecular is solid comprises of a collection of molecules combined together by van der Waals forces and not having covalent or ionic bonds. They are made up of forces atoms or molecules combined by dipole-dipole forces, London dispersion forces or hydrogen bonds. Exmples include graphite and diamonds. The forces between the molecules in  molecular solid is also known as intermolecular forces (IMFs)
