HEEY GUYS!!

today in physics class ms.kozoriz "section 5.1: graphing motion in one dimension" and "section 4.1: properties of vectors". Here are the answers
Section 5.1: Graphing Motion in One Dimension

1. Position(y-axis) Time(x-axis)
2. At the same position
3. Objects at rest
4. Not a finite period of time
5. 0's
6. A
   
7. D
8. B
9. B
10. D
11. C
12. arrows going to the right that are the same distance apart
13. two dots separated from each other
    
14. arrows going to the left that are the same distance apart
    
15. False (4 quantities)
16. True
17. False (d represents the the position at any time)
18. True
19. True

Table One
Segment v a - 0.25km/min
v b - 0
v c - 0.4km/min

Δt a - 10min
Δt b - 7min
Δt c - 13min

Δd a - 2.5km
Δd b - o
Δd c - 5.2km

Table Two
Δt = 30min
distance ran = 7.7 km
displacement = 17.7
average velocity = 0.26 km/min


Section 4.1: Properties of Vectors

1. 6km (E)
2. 6km (N)
3. 6km (NW)
4. 4km (N)
5. 3km (W)
6. 5km (SE)
7. 4m (SW)
8. 12km (E)
9. 20m (SE)
10. 400m (W)
11. b) d=2.0 km north
12. d) d=2.0 km
13. H,F,B
14. B,F,G,I
15. B,F
16. True
17. False (protractor)
18. False (tail)
19. True
20. False

Ms. Kozoriz also taught us something about adding vectors. Here it is if you guys missed it















And for the people that was away, dont forget to hand in the "appendix 3.8: inter pretending position time graph which was due today. and we also received 3 sheets called "section 4.2: components of vectors, Simple Vectors, and a crossword puzzle. so dont forget to pick those up.

Waves in 2 D

Hey guys! This is Mark and I am the scribe for today. Today in class, Ms.Kozoriz gave us our "Waves in One Dimension test" back and she corrected the test with us. Here are the answer to the test if any of you guys missed out on it.

1.

2. Amplitude = 1.5cm
wavelength = 4.5cm

3. Transverse wave

4. Longitudinal Wave

5. Compression, Rest Point, Rarefaction, Amplitude, Compression

6. F=λ/T = 10/0.5s = 20Hz

7. 120s/80 = 1.5s

8.

9. F=λ/T = 240/0.30m/s = 800Hz

10. λ=Z/F = 340ms/510Hz = 0.67m

11. 1)B
2)C
3)C
4)A
5)A

12. a)Destructive
b)Constructive
c)Constructive
d)Destructive

13. A standing wave is a result in of two wave trains of the same wavelength, amplitude traveling an opposite direction through the same medium.
No it doesn't stand still

We also watched a video about "waves in two dimensions" which helped us with our previous assignment "waves in two dimensions - assignment 1" we pretty much did a review on what we did last Friday, and if you look at Lorenz's previews post, it explains what we reviewed in class.

OKAY, THAT'S ALL FOR NOW
