What is the difference between random error and systematic errors ? How do you correct each one ?

A particle moves under constant external force F = F₀ ˆi. It is also subjected to a drag force, F_D = −C_DV. How will the particle move, qualitatively speaking? Describe in words before using equations. What will the particle's final velocity be? What is the sum of the external forces at the final velocity you found?

Q1. What are the Dulong-Petit law and Einstein model for the heat capacity of solids?

FLUID DYNAMICS:

Explain the method of assigning temporal and spatial scales to physical phenomena in fluid dynamics.

Determine the following quantities for a car driving on a level surface with a coefficient of static friction of 0.75 (¾) and a coefficient of kinetic friction of 0.67 (⅔).

1. Determine the car's maximum starting acceleration with and without "burning rubber". How do these two methods of starting a car compare?
2. Determine the car's minimum braking distance with normal brakes and antilock brakes as a function of initial speed. How do these two methods of stopping a car compare?

9. An experiment uses microphone moving toward a speaker as a way to measure the speed of sound in different media. In air, the frequency heard by the moving microphone is 20% higher than the frequency of the sound when the microphone is at rest. When the gas in the experimental system is replaced by helium, the frequency heard by the moving microphone is now only 6.8% higher than when the microphone is at rest. Based on this information, what is the speed of sound in helium?

Explain how and why the velocity of an object changes when it falls in a viscous fluid. 2

1. At the solstices and the equinoxes, how does the right ascension of the Sun compare with the sidereal time at solar noon? Does this relationship hold on other days of the year?

2. On what day of the year is apparent solar time the same as sidereal time? Explain why this would not happen on another day of the year.

Miranda, a satellite of Uranus, is shown in part a of the figure below. It can be modeled as a sphere of radius 242 km and mass 6.68 1019 kg.

(a) Find the free-fall acceleration on its surface. (m/s2)

(b) A cliff on Miranda is 5.00 km high. It appears on the limb at the 11 o'clock position in part a of the figure above and is magnified in part b of the figure above. A devotee of extreme sports runs horizontally off the top of the cliff at 8.50 m/s. For what time interval is he in flight? (Ignore the difference in g between the lip and base of the cliff.) (s)

(c) How far from the base of the vertical cliff does he strike the icy surface of Miranda? m (d) What is his vector impact velocity? (m/s ° below the horizontal)

Along a number line, there exist 2 charged objects. At x = 8 m, there is a 4 nC charge (Q1), and at x = -5 m, there is a -9 nC charge (Q2). What is the electric field at x = 0 m? What is the electric potential at x = 0 m? If a third charge (Q3 = 1.6190 nC) were place on the number line so that it was in equilibrium, where would it be placed? Given the position of Q3 found in the previous problem, what is the total force, stack text F end text with rightwards harpoon with barb upwards on top, on Q1?

Wave forms and Wave Energy

Kinetic energy is often the release of potential energy is a sudden burst. Waves are repeated occurrences of an event that may or may not follow a set pattern. Sometimes this burst can be controlled, and sometimes it is so large, new language was created to compare it to other energy releases. There are also situations where the terminology could is used interchangeably with another term or phrase. And to confuse the issue more, there are phrases here that are commonly used incorrectly.

For this assignment, defining and understanding how the term is used is the goal. Please define the following term
State if it can be practically measured.

If it can be measured, what scalar unit is used.

Finally write a phrase that demonstrates a context you would use this term.

1. Amplitude

2. Waveform

3. Overtone

4. Magnitude

5. Hertz

6. Phase shifting

7. Seismic

8. Decibel

9. Elastic

10.White noise
