Help with number 6 please, thank youu
![Part II. HANDWRITTEN. Show your complete solutions and computations. Quantities have
appropriate units in every step of the solution. Solution is presented in a logical/orderly
manner; All working equations are presented and properly written; figures are drawn
properly; and all relevant details are shown. Overall presentation is also given credit.
1. Given the following measurements (in metric and English respectively) of a metal
cylinder: length = 5.640 cm, 2.274 in; diameter= 2.188 cm, 0.878 in. Determine the
experimental value of the conversion factor from cubic centimeters to cubic inches.
[Use three (3) decimal places].
2. Make a sketch of the appropriate scale showing each of the following readings:
A. Vernier Caliper: 1.475 in B. Micrometer: 7.78 mm
3. Complete a table similar to that in Experiment No.3. Let weight of block equal to 5.60
N for the first trial; a mass of 200 g is added in the next trial. Consider the following results:
Trial 1- applied force for constant velocity is 1.58 N, coefficient of static friction is 0.57; Trial
2- applied force to move object is 4.16 N and 1.97 N to move it at constant velocity. [Use
two (2) decimal places].
4. Consider a situation similar to that in Experiment 2. Given the following distances
traveled (measured from starting point) and times taken: 38.0 cm, 5.9 s; 50 cm, 6.7 s; 85
cm, 8.8 s; and,105.0 cm, 9.8 s. a) Complete the table for average velocity. [Use one (1)
decimal place]. b) Graph position vs time.
5. Consider an Atwood machine similar to that used in the experiment: Each pan has a
mass of 65.50 g. The right pan is made 8.00 g heavier than the left pan. It takes the right
pan 2.52 s to descend from the top platform to the bottom platform 1.24 m below.
Compute the % difference between the true value and experimental values of the
acceleration of the pans. The mass of the pulley is 82.20 g. Express the accelerations in
m/s?. [Use two (2) decimal places]
6. An object with a mass of 85.0 g has a specific gravity of 7.5. a) What is the expected
apparent weight when completely submerged in water?
subsequently submerged in a liquid specimen, the apparent weight is 0.747 N. What is
the specific gravity of the liquid specimen? [Use three (3) decimal places].
When the object is
7. Experiment No.5:
a) Were you able to attain the desired results? In one short sentence, explain why or why
not. b) In the second part of the procedure, if a heavier object is to be hung on the
beam, should the object be brought closer to or farther from the fulcrum (or vertical
support) to balance the beam?](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F1d9cf0a1-4cc2-4982-9704-6b8173f46577%2Fdf94e772-f670-43c4-bb30-1a2f59a818b8%2F1g96pio_processed.jpeg&w=3840&q=75)
