Suppose you have a stone statue of mass MM, and you want to measure its volume....
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...
Chemistry problem: Suppose you have an unknown metal cylinder that has length: 52.4 mm, and diameter: 10.4 mm measured by a caliper. And, the mass of the unknown metal cylinder is 39.8380 g. Then suppose it was placed into a 25 mL graduated cylinder filled with 10mL of water where the solid cylinder is completely submerged in the water and the new water level should be < 25mL. What could approximately or possibly be the final volume of water after...
(1) Suppose you lift a stone that has a mass of 5.3 kilograms off the floor onto a shelf that is 2 meters high. How much work have you done? Joules (2) Suppose you lift a laptop that weighs 3.2 pounds off the floor onto a shelf that is 4 feet high. How much work have you done? foot-pounds (3) The force on a particle is described by 9x^3−1 pounds at a point xx feet along the x-axis. Find the...
I) You want to find the volume of a mtal sphare (Note: the formula for the volume of a sphere is V--πr. where r is the radius of the sphere). You measure the radius of the sphere to be r-2.18 cm, with a measurement uncertainty of± 0.02 cm. What is the volume of the sphere as well as the corresponding uncertainty of the calculated volume? 2) You measure the mass of the same sphere used in qesio, and find that...
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...
you want to measure the gravitational acceleration at your location. since g does not vary significantly over the surface of the earth you will have take very precise measurements you make a simple pendulum by typing a 55 g hex nut to a string of length 1.500 m. you pull the mass to the side and release it to let it oscillate observing that it takes 2.454 s for the mass to return to its original position what is the...
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)...
Lab Exercise 3A Discuss why you think cells would evolve to have a certain shape. Think about tf cells that you looked at earlier with shapes other than a sphere or cube. How doy think a shape other than spherical or cuboidal could help speed up difusion acros 2) the plasma membrane? OSMOSIS ANI QUESTION: CAN THE TONICITY DETERMINED EXPERIMENTALL 3) Mature red blood cells (RBCs) do not have a nucleus, which changes its shape from spherica OBJECTIVES I to...
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...
