Answer:

D) ionic bonds

Explanation:

Polar molecules are defined as the molecules in which we will have two poles or we can say that in these type of molecules the positive and negative center of the charge is separated by small distance.

this system of charge which is separated by small distance is known as dipoles or polar molecules.

Here we know that these two charged molecules will separate by small distance so here the force between these molecules are due to electrostatic force and hence they form a strong bond between the molecules.

This strong bond between charged molecules is known as Ionic Bonds

So here correct answer will be

(D) ionic Bond

A piano wire has a tension of 650 N and a mass per unit length of 0.060 g/cm. What is the speed of waves on this wire
Trava [24]

Answer:

The speed of waves on this wire is 329.14 m/s

Explanation:

Given;

tension of the wire, T = 650 N

mass per unit length, μ = 0.06 g /cm  = 0.006 kg/m

(convert the unit of mass per length in g/cm to kg/m by dividing by 10 = 0.06 / 10 = 0.006 kg/m)

The speed of waves on this wire is given as;

v = \sqrt{\frac{T}{\mu} } \\\\v = \sqrt{\frac{650}{0.006} }\\\\v = 329.14 \ m/s

Therefore, the speed of waves on this wire is 329.14 m/s
