Answer:
(1) Use the data in Table R2 and error propagation rule to compute the travel time ratio (with errors) of the other objects to the hollow cylinder ? ℎ? . Fill in Table R5 below. [6] Table R5 Solid cylinder Billiard ball Racquetball ? ? ℎ? ± ± ± (2) Discuss how the ratio of solid cylinder to hollow cylinder have confirmed or contradicted the theoretical ratio in Eq. (8) in Manual . Compute the % error and make discussions. [4] Answer: (3) From the travel time ratio, please determine (i) whether the billiard ball is solid or hollow, and (ii) whether the racquetball is solid or hollow. Write down your reasons. (The answer can be uncertain if your measurements do not show enough information.) [4]

Please discuss the reason for this relatively largeSEOM and how to improveit. [3] (5) Please discuss TWO possible systematic errors in the measurement. [3] Answer: **Attach your calculation details. Use as many paper sheets as you need. Calculations that demonstrate your understandings may gain you partial credit. **Make sure your work-area and equipment are the same as they were before you leave.
Explanation:
The answer for this problem is clarified through this, the
system is absorbing (+). And now see that it uses that the SURROUNDINGS are
doing 84 KJ of work. Any time a system is overshadowing work done on it by the
surroundings the sign will be +. So it's just 12.4 KJ + 4.2 = 16.6 KJ.
C.Earth is the largest and most dense of the terrestrial planets
Newtons first law states an object will only move of something acts on it. his seccond law states that an object will accelerate if an outside force acts on it.
Answer:
1962 W
Explanation:
P = W/t
P = F d cos theta / t
P = (500 kg) (9.81 m/s^2) (10 m) (cos 180) / 25 s <-- the displacement and the force act in opposite directions (but it doesn't matter because direction doesn't matter in this case)
P = 1962 W
