a note higher than middle c has the greatest frequency. Hence option D is correct.

What is Wave ?

Wave is is a disturbance in a medium that carries energy as well as momentum . wave is characterized by amplitude, wavelength and phase. Amplitude is the greatest distance that the particles are vibrating. especially a sound or radio wave, moves up and down. Amplitude is a measure of loudness of a sound wave. More amplitude means more loud is the sound wave.

Wavelength is the distance between two points on the wave which are in same phase. Phase is the position of a wave at a point at time t on a waveform. There are two types of the wave longitudinal wave and transverse wave.

Hence option D is correct.

A force of 5 N gives to mass my and an acceleration of 8m/s2 and a mass m2an acceleration of 24m/s2. What acceleration would it give if both masses are
tied together

Answers

Answer:

a=6m/sec²

Explanation:

f=5 N

a1=8m/sec²

a2=24m/sec

m1=f/a1=5/8kg

m2=f/a2=5/24kg

New, f=(m1+m2)a

a=5/5/8+5/24=5/15+5/24=24*5/20

a=6m/sec²

What molecules has a zero dipole moment?

Answers

Answer:

Nonpolar molecules

Explanation:

Nonpolar molecules are those molecules that are produced by the union between atoms that have equal electronegativity, so the forces with which the atoms that make up the molecule attract the electrons of the bond are equal, thus causing the cancellation of these forces. An example of an nonpolar molecule is the Oxygen (O2) molecule. In this molecule each oxygen atom attracts the electrons shared towards itself with the same intensity but in opposite directions, therefore the forces of attraction are annulled and the molecule does not become a dipole.

A small plastic sphere with a charge of -6.0 nC is near another small plastic sphere with a charge of -14 nC . If the spheres repel one another with a force of magnitude 8.3×10−4 N , what is the distance between the spheres?

Answers

Here is how to answer the question.

Use the formula:
F = kq1q2/r^2 

F = force = 8.3x10^-4N 
q1, q2 = charges 
r = separatioon 
k = constant = 9x10^9 in MKS units 

so we have 

r = sqrt[k q1 q2/F]
r = sqrt[9x10^9*(-14)x10^-9 * (-6)x10^-9 / 8.3x10^-4 ]
r = 0.0302 m

So the distance between spheres is 0.0302 m
