1)How many images would you get for an object that is placed between two mirrors placed at an angle less than 90(degrees)?

2) What happens to the images of this angle is it is bigger than 90(degrees)?

3) How do mirrors produce funny images?


1)i would get 2 virtual images of the object.but if the degree of both the mirrors decreases,i would end up getting 4 or more virtual images of the object.
here are the picture results i gathered.

2 mirrors placed at an angle of 90degree

2 mirrors placedin an angle less than 90degree.

2)there are only 2 virtual images.

3)it is due to the concave and convex mirrors that produces funny images of ani object placed infront of it.

2) Reports have linked charred food to cancer. How safe is BBQ food ?

my thoughts and findings:

It is true that the charred food do leads to cancer.this is due to the fact that charred food contains carcinogens.Carcinogens is in any form of substance,radionuclide or radiation.
they are angaged in the exacerbation of cancer or in an increase ot its propagation.This may be due to the ability to damage the genome or to the disruption of cellular metabolic processes.simple to explain that they are a type of substances that cause a normal cell to change into a cancerous cell.

cancer had made some people to concerned about grilling and grilled foods.it is a disease that damaged cells of the patient's body do not undergo programmed cell death and their growth is no longer controlled.carcinogens increase the risk of getting cancer by altering cellular metabolism or damaging the DNA directly in cells, that interferes with biological processes, and induces the uncontrolled, malignant division, ultimately leading to the formation of tumors.

when DNA are damaged,they are too severe to repair and leads to programmed cell death.if the programmed cell death pathway is damaged, then the cell cannot prevent itself from becoming a cancer cell.


to avoid the chances of getting cancer,we should be physically present to "look at" the food that is being grilled.it is to prevent the food from being charred and at the same time avoid eating charred food and it will thus,minimise the chances of a person getting cancer.

E LEARNING ASSIGNMENT PART 2 for REGISTER NUMBERS 11 - 20

question:What would be the effect if a spaceship landed, and the aliens in it estimate that they are 400 years ahead of us. What would happen if they offered us all their scientific knowledge? Would it be good or bad? Why?

answer:as said that the aliens are 400 years ahead of us and if the aliens were to offer their scientific knowledge to us,i'm sure that we can solve the problems that earth is currently facing.like the different dieases that doesn't have any cure.global warming issues that have been causing the world to change.it is good as with their help,the world might be in a better enviroment for us to live in.

Sewing Machine
yes,i was amazed by a normal sewing machine.why?Its because,it has helped to lessen the time taken for us to make our clothes and fabric needed in our daily lives.a sweing machine is textile machine used to stitch fabric together with thread.And it was invented during the first industrial revolution to lighten and decrease the amount of manual work a person has to do.The sewing machine has vastly improved the effiency and productivity of clothings and fabric in the world.
the needle of the sewing machine has a total of six parts.the shank,shaft,eye,point,groove and the scarf.The groove leads the thread into the eye from the front.while the scarf is a cut in in back of the eye and aids the bobbin shuttle to pick up the thread.
