Answer:

Electronegative atom will create a stronger negative charge is true.

Explanation:

Given that,

Electronegativity affects the strength of intermolecular forces.

We know that,

Electronegativity :

Electronegativity is a ability of an atom, shared electron to itself.

In periodic table,

When we move left to right in period then the electronegativity increases.

When we move up to down in a group then the electronegativity decreases.

We know that,

The intermolecular forces are dipole-dipole interactions which is the strongest intermolecular force of attraction.

If the electronegativity of atom is more, then the atom gain negative charge.

When the attraction force is more in atoms then the electronegative will be more.

Hence, Electronegative atom will create a stronger negative charge is true.

Anvisha [2.4K]

Answer:

1/6 m/s^2      ( about 1/6th gravity of Earth ( 9.81 m/s^2)

Explanation:

Displacement =  yo  +  vo t  - 1/2 a t^2

      -  3.2          = 0     +  0     - 1/2 a(2.0)^2

      -     3.2       =                -2a

             a = 3.2 / 2 = 1.6 m/s^2

Consider a 2.54-cm-diameter power line for which the potential difference from the ground, 19.6 m below, to the power line is 11
tiny-mole [99]

Answer:

The line charge density is 1.59\times10^{-4}\ C/m

Explanation:

Given that,

Diameter = 2.54 cm

Distance = 19.6 m

Potential difference = 115 kV

We need to calculate the line charge density

Using formula of potential difference

V=EA

V=\dfrac{\lambda}{2\pi\epsilon_{0}r}\times\pi r^2

\lambda=\dfrac{V\times2\epsilon_{0}}{r}

Where, r = radius

V = potential difference

Put the value into the formula

\lambda=\dfrac{115\times10^{3}\times2\times8.8\times10^{-12}}{1.27\times10^{-2}}

\lambda=1.59\times10^{-4}\ C/m

Hence, The line charge density is 1.59\times10^{-4}\ C/m

Which variety of moth, C or Y, is more likely to be killed by insect eating birds?
Svetlanka [38]
Moth X is more likely to be eaten by insect killing birds first. This is because Moth Y blends in with the tree trunk more and is hidden from birds. Its wings camouflage with the tree trunk, hiding it from sight.

Two identical blocks are heated to different temperatures. The blocks are placed so that they touch, and heat begins to flow bet
baherus [9]

The pair of blocks is insulated, so no energy escapes. The pair of temperatures possible is  95 +95 temperature blocks.

<h3>What is thermal equilibrium?</h3>

When two objects are in direct contact and transfer heat through conduction. When the both object attain same temperature after sometime, they are called in thermal equilibrium.

Two identical blocks are heated to different temperatures. The blocks are placed so that they touch, and heat begins to flow between blocks. The heat will continue to until and unless they have same temperatures. After they being isolated, the temperature of both will be same and no heat is transferred outside.

Thus, the pair of temperatures possible is  95 +95 temperature blocks.
