Answer:

Sample Response: Sonia observed that the two balloons repelled each other. This is because both balloons acquired the same charge when she rubbed them with the piece of wool, and like charges repel each other.

Answer: They will repel each other.

Explanation:

Two inflated balloons when rubbed with woolen cloth will lead to repeal each other because of the similar charges on both the balloons.

Rubbing both the balloons together by the woolen cloth will introduce negative charge in the balloons.

As, we know that the same charges repeal each other both of the balloons with be apart from each other.

This is due to the static electricity, the negatively charged particles jump to the positive one. When balloons are rubbed they become negatively charged.

light waves are first transmitted through the ________ at the front of the eye and enter an opening called the ________ before s
viva [34]

The transmission of light waves is usually done through cornea of the eyes, then move through another opening which is regarded as pupil before it will get to the retina.

  • Light waves can be regarded as moving energy which contains microscopic particles known as photons.
  • The vision of the eye can be completed through the light wave passing through the components of the eyes and this process goes thus;
  • Light will move through the (cornea) which is situated at the front area of the eyes into lens.
  • Then both the cornea and the lens give room for the focusing of the light rays to the retina which is situated at the back of the eye .
  • Then through the help of the cells in the retina, the light will be absorbed and then be converted to  electrochemical impulses and then transfer it to the brain as well as optic nerve.

Therefore, light wave are form of tiny microscopic particles.

If a total of 1250 offspring were obtained from your cross, determine the number of offspring that you would expect to obtain th
irakobra [83]

Answer:

106 single crossover events

Explanation:

Total number of offspring = 1250

<u>Determine the number of offspring that would be expected </u>

( Rf between the genes vg and Pr ) * ( Total number of progeny )

  =   0.125 * 1250 ≈ 156 ( value for single and double crossovers )

next :

( value of the Rf of double crossovers ) * ( Total number of progeny )

= (0.322 * 0.125) = 0.04025  * 1250 = 50

Hence the number of offspring expected to obtain/represent a single crossover event between pr and vg

=  156 - 50 =  106

A boy swings a ball on a string at constant speed in a circle that has a circumference equal to 6 m. What is the work done on th
Grace [21]

Answer:

0 J

Explanation:

From the diagram below; we would notice that the Force (F) = Tension (T)

Also the angle θ adjacent to the perpendicular line = 90 °

The Workdone W = F. d

W = Fd cos θ

W = Fd cos 90°

W = Fd (0)

W = 0 J

Hence the force is perpendicular to the direction of displacement and the net work done in a circular motion in one complete revolution is = 0
