Unit 2 Physics Question Paper

It is very important to try hard to reduce your chances of getting an illness or getting injured. For example, when you go snowboarding during the winter, it is very important that you wear enough clothing to stay warm and don’t get cold. Also, it is important that you wear protective gear to keep you safe. Also, if you have a certain disease, it is important that you take care of it. Like for people with asthma, they have to make sure they take their medication so that they can reduce the risk of them having an attack. Another thing you can do is make sure you get vaccinated for diseases. I hope that through this issue, you can learn the different ways to reduce your chances of getting an illness or infection.

axis be parallel to the ground and the positive y axis point upward. In the time interval from

Atomic mass of calcium is 40. The mass of 2.5 gram atoms of calcium is _______.

For each question, choose the answer you consider to be the best and indicate your choice

Displacement is the difference between where you start and where you end up. Since me and my dog start and end at the same place, we will have the same displacement. The distance traveled by me and the dog would be different. The dog took many short side trips while I would have walked straight to the park. The dogs side trips amounted for the gap between me and my dogs distance. If you take a trip and then return home, your odometer does not read zero. Instead it records the amount of miles you traveled by car. That is why an odometer in a car measures distance.

What was the shape of your velocity vs. time graph? Explain what the shape of the graph tells you about the motion of the car.

However, in order to find a linear slope of a parabolic curve, the mathematical equation of distance/time^2 ( pertaining to the data as cm/s^2) is used to produce the linearization of the distance-time graph. A linear distance-time graph is the equivalent of a velocity-time graph by identifying the slope of the distance-time graph. Another best fit line (a linear trendline) was plotted within the newly charted velocity-time graph. The equation identified through the trendline was Velocity=808.578cm/s^2 (t) +44.450 cm/s. The 44.450cm/s represents the point in which the linear data crosses the y-axis as the y-intercept. Additionally, the 808.578cm/s^2 represents the slope of the velocity-time graph in which the acceleration can be

Generally, pollution prevention (P2) is about to prevent source of pollutant being produced or to reduce the amount of pollutants and waste created. P2 is an effective means to protect the environment and it is inexpensive because it involves the conservation of natural resources (such as water), efficient use of energy and the use of materials. Besides that, it also promote sustainable development by reusing materials that still in a reusable manner, the use of nontoxic or less toxic substances or changing the manufacture processes in both reducing or removing waste at the source.

B. Find all times t in the interval [0,10], if any, when the particle changes direction. Justify your answer.

After reading the question I was confident I could answer the question correctly and provide adequate demonstration for the solution. First step of the question was to use a fraction to find part of the whole number. The second step subtraction using the total of the leaflets and subtracting the yellow leaflets to give the amount of blue leaflets. Step three required taking the total amount of blue leaflets and using a percentage to answer the amount of smudged leaflets. I converted the percentage to a fraction to construct an equation. To solve the equation I cancelled the zeros from 800 and 100 next I multiplied 8 x 5 giving the total of 40, the correct answer. Another method to solve this problem.

Life is about challenging yourself intellectually in order to succeed. I had to challenge myself intellectually in my Physics 11 class. Physics 11 involves a lot critical thinking and connection making in order to understand the concepts. Also, my teacher didn't speak fluent English which made it very difficult to understand, and he didn't give any notes either. I had to adjust to how my teacher taught us, which was difficult, but it helped challenge me intellectually. I made a decision to do as much work as I needed to do well in this class. Every class I made my own notes and reviewed them at home. The textbook I received from my teacher, I used to investigate key ideas for the chapter we learned that day. At home I did the questions the

Directly compare two objects with a measurable attribute in common, to see which object has "more of"/"less of" the attribute, and describe the difference. For example, directly compare the heights of two children and describe one child as taller/shorter.

mass something has, relative to its volume. For example, compare a bowling ball to a basketball.

“The quantitative way of relating the object distance d-sub o with the image distance d-sub i for a lens given by the then-lens equation (1/d-sub o)+(1/d-sub i)=1/f. Rearrange to show that d-sub i=(d-sub o)(f)/(d-sub o)-(f)”

You and your friend decided to take your brand-new red sports car out for a spin. Your car is capable of speeds up to 220 mph. You drove 45 miles in 1.25 hours. At the end of your trip, your friend tells you that your average speed during the trip is 36 miles per hour. You were appalled. You asked yourself, 'How can a sports car have such a pitiful average speed?' and tried to recall how much you paid for it. What is average speed
