Hi, Can you check my answers? If they're incorrect, please include a picture of the correct answer written out on a peice of paper. Thanks!! c. When a spherical object of radius r moves at velocity v in a viscous liquid, the object experi- ences a drag force given by Stokes' Law (Fd = 6πrv. η). Given the apparent weight of the object above, under what condition would the object be falling at "terminal velocity"? State the equation for this...
Hi, Can you please check questions 1-3, to ensure they're the correct and include the answer for number 4? Much appreciated. Pre-lab Questions What does it mean when an oscillation exhibits simple harmonic motion? It neans The oscillationr force (ond hence tne acceleration is directly proporhional to me dis placement. 2. Define the angular frequency in terms of the period of oscillation for a simple harmonic motion. 3. Explain what the phase is in simple harmonic motion. on in found...
hi is my answer right if not please check it thank you Astrophysicists investigating the solar system find a group of potentially hazardous 'near Earth objects' (NEOs) within the asteroid belt. They find the diameter of these NEOs has a mean of 1.75km and standard deviation 0.5km. Assuming the diameters are Normally distributed, what is the probability that for a randomly selected NEO amongst the group, the diameter is: Note: Only put final answers and all answers must be in...
can you help me figure out the following: part a: Calculate the specific gravity for aluminum and for brass. part b: Calculate the specific gravity for cork. part c: Calculate the specific gravity of the isopropyl alcohol. Experiment 9 Specific Gravity (Archimedes Principle) Read the Theory section on pages 9-2 & 9-3. Specific gravity is defined as the density (mass per unit volume) of a substance relative to the density of (liquid) water: s p/po, where pe is the density...

Hi, please help me check my answers for two physics problems. If they are wrong, please explain it so I could learn and correct the mistake. Thank you. [For the first problem, I got: push= 2598J, normal= 0, weight= 0, friction= -1920J. I calculated net work to be 678J ] [For the second problem, I got push=250J, normal and weight= 0, friction = -200J. I calculated net force to be 50J, which is positive] 3. A dockworker pushes a 50...
Hi can you check/help me with these? And please explain if you can! Thank you! These questions are about Ion-exchange Chromatography 1. The charge on the column is negative a. Would the protein KLGVRQYWRRRRPLYWTV bind to it? 2. Does the buffer action work by a difference in ionic strength? 3. 4. T/F: You will likely get more fractions of DNP-glycine than the other two proteins. True because DNP-glycine goes through very fast because it is small. 5. T/F: Cytochrome c...

Indicate whether each item is true or false. If an item is false, please correct it so that it is true. Speed is a scalar quantity. Work and energy are vector quantities. Objects that are not moving cannot have any work done to them. Pressure is uniform throughout a fluid, regardless of depth Density of a material changes as the temperature of the material changes. Solids are always more dense than liquids. Liquids are always more dense than gases Falling...
