i need help. lab 6 only (Atomic spectra). the other labs we will do later so if i pass Lab 6 then i will contact you again. but for now just handle Lab 6. how much?
i want to do the questions from this lab report 10.1 page 95 1. Question on the masurment: a) is the image enlarged or reduced when s > 2 f ? is the image enlarged or reduced when s < 2 f ? b) is the image erect or inverted ? is the image real or virtual ? why? page 96 2.Explain why for a fixed separation between the object and the screen (i.e., s+ s' is fixed), there are two positions of the lens at which the image formed on the screen are in foucs (clear image). 3. A lens forms an image of an object. the objet is 16 cm from the lens. The image is 12 cm from the lens on the same side as the object. (a)what is the focal length of th lens?? is the lens converging or diverging ? (b)if the object is 8.5 mm tall, how tall is the image? is it erect or inverted? (c)DRAW a principle-ray diagram. 10.2 page 99 1. Hold the optics bench by your hand, look at the tree outside window using your telescope. is there image of the tree erect or inverted? is the image of the tree enlarged or reduced? 2.The worlds largest refracting telescope is at the Yerkes Observation of the University od Chicago at Williams Bay, Wisconsin. the objective has diameter of 102 cm and focal length of 19.5 m. the focal length of the eyepiece is 10 cm. What is its magnification (or magnifying power)? and if possible complete the calculation for table 1 and 2 (show calculation typed or written is fine)
PLease refer to page 6 for the same obejectives listed below this must be done by Sunday 2/22/205 5:30 PM EST Must be in a word document Must have 3 excel charts as pictured in the book Please no plagerism 100% orginal l . Objective (in your own words) 2. Theory (one paragraph, in your own words) 3, I will do this 4. Data: - Answers to the Prediction questions - Create your own table with the results as in the pictures below using table 1 and table 2 and fill out the Analysis part this all must be done in excel, predicted values, instrumental uncertainties. 5. Analysis: - Compare predicted and measured values - Does the measured value full within the error margin of the calculated value? If nor, whai might be the reas on. (''Human Error" is not an acceptable response) 6. Conclusion: Discuss your results ill terms of the objectives. In each study, done in this experiment, discuss how your results compare to theoretical expectations. Some ideas for the discussion are given below. but the discussion is not limited to these pomts only. - What happens to the currents through a series circuit as more light bulbs are. added in series? What happens to the voltage across each bulb as more light bulbs are added in series? What happens to the current through a parallel circuit as more light bulbs are added in parallel? What happens to the voltage across each bulb as more light bulbs are added in parallel?
1) If Angle "a" is 25o, Angle "b" is: 2) If Angle "a" is 25o, Angle "b" is: 3) If Angle "a" is 25o, Angle "d" is: 4) f the wavelength of orange light is 6 · 10-7 m, calculate its frequency. f = 6) For a closer look in shaving, a: 7) Full-length mirrors used while dressing are: 8) A 2.0 X 2.0 -inch slide is placed before a converging lens 21 inch in front of the focal point. If the focal length is 20. inches, how large is the image that is projected on the screen? 11) Four beats per second are heard when an unknown tuning fork and a 240 Hz tuning fork are struck simultaneously. What are the two possible frequencies of the tuning fork? 12) The echo of your footsteps returns in 0.50 second. How long is the corridor in which you are walking?

11 QUESTIONS TOTAL 1. In exploring Newton's laws, it is important to keep in mind all the forces that are at work in a given system and what their net effect is on a body. Suppose you simultaneously drop a hammer and a feather from the same height on the surface of the earth. Which will reach the ground first? Suppose you then do the same experiment on the surface of the moon. Does anything change? If so, what? Explain all your answers using what you have learned about Newton's laws of motion. (There are some great video clips of this actual experiment online.) (at least 100 words response on this question) ONE STEP CALCULATIONS Conversion factors: 1kg weighs 10 N at Earth’s surface: 1 N = 0.22 LB Weight = mg 3. An apple weighs about 1 N. What is its mass in kilograms? What is its weight in pounds? Acceleration: a= Fnet M 6. a) Calculate the acceleration of a 2 kg block on a horizontal friction-free air table when you exert a horizontal net force of 20 N. b) What acceleration occurs if the friction force is 4 N? Force: F=ma 8. Calculate the horizontal force that must be applied to produce an acceleration of 1.8 g for a 1.2 kg puck on a horizontal friction free air table. EXERCISES 5. Before the time of Galileo and Newton, it was thought by many learned scholars that a stone dropped from the top of a tall mast on a moving ship would fall vertically and hit the deck behind the mast by a distance equal to how far the ship had moved forward while the stone was falling. In light of your understanding of Newton’s laws, what do you think about this idea? 11. A common saying goes, “Its not the fall that hurts you: it’s the sudden stop.” Translate this into Newton’s laws of motion. 13. If you drop an object, its acceleration toward the ground is 10 m/s square. If you throw it down instead, would its acceleration after throwing be greater than 10 m/s sq? Ignore air resistance. Why or why not? 17. You hold an apple over your head. a. Identify all the forces acting on the apple and their reaction forces. b. When you drop the apple, identify all the forces acting on it as it falls and the corresponding reaction forces. 27. If a Mack truck and motorcycle have a head-on collision, upon which vehicle is the impact force greater? Which vehicle undergoes the greater change in its motion? Explain your answers. 34. Free fall is motion in which gravity is the only force acting. a. Is a skydiver who has reached terminal speed in free fall? b. Is a satellite circling Earth above the atmosphere in free fall? 39. Which is more likely to break, the ropes supporting a hammock stretched tightly between a pair of trees or one that sags more when you sit on it? Defend your answer.
A block is at rest on the incline shown in the figure. The coefficients of static and kinetic friction are ?s = 0.75 and ?k = 0.64, respectively. The acceleration of gravity is 9.8 m/s2 . What is the frictional force acting on the 38 kg mass? Answer in units of N
1. A charge of +3.5 µC is placed on the x axis at x = +0.55 m, while a charge of -15 µC is placed at the origin. (a) Calculate the magnitude and direction of the net electric field on the x-axis at x = +0.8 m. (b) Determine the magnitude and direction of the force that would act on a charge of – 8.0 µC if it was placed on the x axis at x = + 0.8 m. Solution: a) The electric field from a point charge is given by E = k|q|/r^2 E points towards a – charge and array from a + charge. Both electric field points in the same direction so we just add them together E (net) = (8.99*10^9 Nm^2/C^2 * 3.5*10^-6 C)/ 0.55^2 + (8.99*10^9 Nm^2/C^2 * 15*10^-6 C)/ 0.8^2 E (net) = 2.9* 10^5 N/C +x direction b) ?
