The Grid Question of Science Mid Term Examination of International Class 2022

Assalamualaikum warohamtuloohi wabarokatuh

How are the students in class VIII-G and VIII-H? Hopefully you will always be in a healthy condition and stay enthusiastic in carrying out science mid term examination of International Class. There are 10 multiple choice questions questions and 2 essay for this exam. Here are there materials for mid term science examination of class VIII-G and VIII-H : 

1. Student can mention an example of force acting over a large area to produce a small pressure.

2. Presented the data about investigate pressure. The data of the table gives the weight of each person and total area of contact between the person and the nails. Student can which person experiences the least pressure from the nails.

3. Student can calculate the pressure exerted at the base of the dam due to the water if the depth of the water is 100 m. The density of the water is 2000 kg/m^3. The gravitional filed strenght g is 10 N/kg. 

4. Students can determine the equation used to find the pressure caused by a liquid can be written as P = h x A x B where p is the pressure and h is the depth of the liquid. Which the right things gives the quantities A and B.

5. Students can calculate the force acting on the plug due to the water if a washbasin has an exit pipe coverede with a plug of area 28 cm^2. A chain is attached to the centre of the plug to assist in pulling the plug away from the exit hole. The washbasin contains water to a depth of 0.16 m. The density of the water is 1000 kg/m^3. 

6. Students can determine the route is taken by air passing into the lungs of a human.

7. Students can determine the place that exchange of oxygen and carbon dioxide. 

8. Students can mention the reason the pleural cavity have fluid.

9. Students can mention which of the following happens when you inhale and exhale. 

10. Students can mention which respiratory disorder causes the muscles around the bronchial tubes to tighten from time to time and restricts breathing.

11. Students can calculate the force exerted by the other piston if in hydraulic press a force of 40 N is applied to a piston of area 0.40 m^2. The area of the other piston is 4 m^2. 

12. Presented the figure of the human gas exchange system, students can mention the part of the name of that organ respiratory system and its function. 

Hopefully the students of class VIII-G and VIII-H will be given fluency in answering science tryout which will be held on Friday, February 24, 2022. Keep the enthusiasm for learning and always keep your health. Aamin
