The supersonic aircraft Concorde has a length of 63.0 meters when sitting on the ground on a typical day when the temperature is 18.0 Celsius. The Concorde is primarily made of aluminum. In flight at twice the speed of sound, friction with the air warms the Concorde’s skin and causes the aircraft to lengthen by 21.0 cm.

A 11.0 g bullet is fired horizontally into a 102 g wooden block that is initially at rest on a frictionless horizontal surface and connected to a spring having spring constant 151 N/m. The bullet becomes embedded in the block. If the bullet-block system compresses the spring by a maximum of 74.0 cm, what was the speed of the bullet at impact with the block?

An automobile club plans to race a 770 kg car at the local racetrack. The car needs to be able to travel around several 160 m radius curves at 85 km/h. What should the banking angle of the curves be so that the force of the pavement on the tires of the car is in the normal direction? (Hint: What does this requirement tell you about the frictional force?)

Problem 2Part AMaxwell’s equations can be used to show that electromagnetic waves can propagate throughspace .( a ) Describe the key aspects of an electromagnetic wave . Your description should mentionthe electric and magnetic fields , direction of propagation , and speed . A diagram would be*useful in explaining these concepts .( b ) At some point in space , a sinusoidal electromagnetic wave has an intensity of 2.5 Wm – 2Calculate the amplitudes of the electric field and the magnetic field at this point . Ensurethat you include units .( C ) An unpolarised beam of light , travelling horizontally , with an intensity of Jin = 2.5 WM – 2)is passed , sequentially , through two polarisers as shown in the figure . The transmission*axis of the first polariser is vertical . The transmission axis of the second polariser is at anangle ! to the first . The transmitted intensity after the second polariser is measured to be*Tout = 0. 85 WM- 2 . What is the angle A between the polarisers ?LinI outPart B ( Advanced )A double slit interference pattern is observed on a screen 1 . 0 m behind the slit . The separationof the slits is 0 . 25 mm , and the width of each slit is much smaller than the separation . The slit*is simultaneously illuminated with two laser light sources _ a green laser with wavelength 532Am and a blue laser with wavelength 355 Am . Describe the pattern observed on the screen .

POSTLAB QUESTIONS Name : 1 . Identify the test you would perform to detect the presence of! Fat Sudan Starch Protein Reducing sugar 2

Need help with the following documents.

  1. Identify the test you would perform to detect the presence of:
  2. Fat
  3. Starch
  4. Protein
  5. Reducing sugar
  1. Sucrose is a disaccharide. Yet, it tested negative for the presence of a reducing sugar. What can you conclude about the chemical structure of sucrose?
  2. Why is it important to include bothy a positive control and a negative control when carrying out tests for organic compounds?
  3. What substrate would fit into the active site of pepsin?
  4. What substrate would fit into the active site of amino peptidase ?
  5. Name the product(s) formed when proteins are hydrolyzed in the stomach?
  6. Name the products formed when peptides are hydrolyzed in the small intestine?
  7. Amylase is an enzyme that catalyzes the hydrolysis of starch. It is produced by your salivary glands as well as your pancreas, and has an optimal pH of 6.8. What does the phrase “optimal pH of 6.8 mean?
  8. List at three environmental factors that influence enzyme activity.
  9. What do you mean when we say that an enzyme has been “denatured”?
  10. Why do most enzymes function poorly at very low temperatures ?

The Case: It’s a warm Fourth of July and you are walking across the park to your favorite picnic spot. You are allergic to and highly phobic about bee stings. While walking, you hear a buzzing sound to your right. You turn your head and see a large bee hovering over your right shoulder. You reach with your left hand to swat the bee, but just as you make contact, it stings your shoulder anyway. You notice that you are sweating and your skin turns red. You realize that your Epi-pen was left in the car, so you panic and begin sprinting back to the car to get it.’

Question: Trace the image of the bee to perception. (Include all focusing, transduction, transmission and perception processes and structures)
