You have two objects made of the same substance. Object 1 is a cube with a mass of 465.5 g. You measure the side of the cube using a ruler and find it to be 3.17 cm. Object 2 is a sphere with a mass of 232.8 g. You find the volume of the sphere using water displacement. The volume of the water in a graduated cylinder initially is 120.0 mL, and when the sphere is added the new volume...

Biochemistry Question
You are studying the enzyme Holidase (53 kDa) and want to measure its kinetics (its reaction rates). Holidase catalyzes the conversion of the substrate SPBRK into the small molecule product VCTN. Neither SPBRK or VCTN are colored, which means you cannot measure those concentrations directly, but you do have a polyclonal Gt anti VCTN antibody as well as a monoclonal Ms anti VCTN antibody which you hope will be useful. What antibody technique that we covered in class...

Suppose have the ability to vary the mass m of the bob and the length ? of the string. You decide to to conduct an experiment and realize you can also easily adjust the Amplitude A of the back and forth motion. Of course, just as any good experimentalist would, you are careful to vary one of these quantities at a time and measure the period of the pendulum, recording the data in the table below Mass (kg)Length (m)Amplitude (m)...

To determine the volume of a sphere, you measure its diameter using a ruler an obtain a value of 15.2 mm for the diameter. Using this diameter, you convert the diameter to units of centimeters by dividing the radius by 10 mm/cm and then you divide the diameter by 2 to obtain the radius (r). You then use the equation V = 4/3rr to obtain the volume of the sphere. To determine the mass, you measure the mass on a...

Problem 1 (Excel You have a need to determine the density of a material you are working with. To do this you take a sample of the material and measure both the mass and volume. In order to determine how accurate your measurements are, you take a series of 100 repeated volume measurements and 50 repeated mass measurements (data below) Use this data to determine the standard deviation in your volume and mass measurements ou want to calculate how precisely...
